Very well said Kevin, couldn't have explained it better. Yes, I understood everything you explained - this is why back in the 90's I conquered all other dragbikes! Played with valve overlap (staggered) until it produced the best power for my engine. Ran 8.64's back then. Cheers.
Absolutely a great and direct video. I can't tell you how many customers drop in wanting a cam their buddy has due to a Dyno sheets max numbers at WOT and 6500 RPM. I suggest they ride their buddies bike for 100 miles and be honest about what they feel. They usually come back and tell me their stock bike was actually more enjoyable than the "tricked out" one with the exception of a WOT sprint. I then begin to discuss a realistic cam choice for their engine and bike combination and their realistic riding style.
Thank you Max. People often ask me how they can know if the advice they are getting is good advice. My answer...."you'll know by the quality and number of questions they ask you before they give the advice." Good on you sir!
@@KevinBaxter That is an excellent statement to live by. When I use to manage a fleet if equipment....my superior mentioned to me more than once that some of the operators complained about me asking too many questions....as if they were being interrogated....ha ha. But seriously....I really appreciate your outlook and style. Thank you.
Been building and repairing engines of all kinds for over 20 years and I learned several things about choosing cams my old school teachers may have tried to teach me but didn't sink in. Thanks Kevin I appreciate it very much
great schooling on cams and cam selection.i bought a new roadking in 2002 still have it.it ran like a slug, it always felt like it was chocking. I put an air filter and backing plate, Harley freeflow mufflers all screaming eagle and a dealership download still not as ballsy as my 1977 shovelhead. then on to a stage 2, 95"kit 203 cams, and a download.very disappointed in the performance. years later I put a fueling cam (525) lift, oil pump, cam plate, gear-driven cams, lifters. adjustable pushrods and, and a Daytona twin-tec 2 tuner. now it runs as it should, I downloaded the tune myself. my point here is if I had seen your video 10 years ago I would have saved some $$ and aggravation, never too late to learn even at 65 yr old. thank you, keep the info coming!
2018 FLTRU with 74,000kms. on it. Went with a SE Power Cam. Works great for me as I do 99.9% of my riding on the highway. Also SE 4" slips ons and an upgraded oil pump, after market airflow. It's awesome on the highway, anything above 3000 rpm it takes off like crazy.
Kevin, as a mechanic (autos) for close to 40 years, I love your videos. Always learn something. Always believed in synthetics, after your video switched to Amsoil. This is another good one! Choose the cam for your riding style! Not your buddy’s Dyno printout!
Great video Kevin,, this has to be the best explanation of what a cam is and how it works and why, hands down outstanding work lad. If this is the basics, I've got some studying to do before the intermediate lesson.
This is a dominating topic on so many forums. Most look at peak numbers and how it sounds at idle and end up unhappy with the results. I'll be the first to admit. I almost made the wrong decision when choosing a cam. Thankfully I had someone who asked me all the right questions before I spent hundreds of dollars on the incorrect parts. People, please trust the advice of professionals like Kevin Baxter and get it done right the first time.
My promise to the viewers of the channel has always been to say when something is good...regardless of brand. That includes the folks that work on these things if i can personally vouch for them. I'm not surprised he asked you the right questions..proves what I knew. Rob Swartz at Rob's Dyno in Gardner, MA knows what he's doing. If you're in his area, check him out.
With the almost infinite number of cams available choosing the right one, or two for twin cams can be overwhelming. I usually just ask where do you want your power to kick in and go from there. Fortunately most of the manufacturers are good at giving a fair description of how their different cams perform at different rpm ranges. As for which manufacturer to go with sometimes that just comes down to personal preference and past experience.
I have a '19 ultra and did an SE Torque Cam as soon as i bought it for a 7k mile trip out west. I've been very pleased with it. I've since replaced my oil pump and cam plate (for piece of mind) with an s&s because of the HD oil pump issues but left the SE cam in because honestly its pretty damn good. I know people will have an issue with that but i have TONS of torque with the SE cam and i really dont need any more performance out of my 114 highway cruiser!
I also went with the SE cam, but went with the 462 power cam, max torque is 116.5 at 3500 rpms, power is at 102.5, , the voiding the factory warranty and getting good power n torque, while running a vance n hines power duals and the free Rinehart slip ons, a nice simple stage 2 build on the 114 is all I need n more riding 2 up just swapped to a new road glide limited 2021 from a 2014 ultra classis 103 with just a stage 1 with all vance n hines pipes, had plenty of power n torque with that bike 2 riding 2 up , in rolling hills
The more that I learn the more I know that I don't know. I have a year before I have the bike payed off anyway. Thanks for sharing. I kind of understood.
That was a great refresher. I remember geeking out over stuff like that in Hot Rod, Chevy High Performance, and Car Craft when I was a kid, but I had forgotten some of those details. So this was a good watch, since I've been looking at cams for my old Evo.
Great information Kevin. I am getting a better understanding of the overall importance of the collective relationship between all the other working components along with the cams for my V-Twin. Thanks again. Great content.
Thank you very much Kevin for explaining all this details of Harley Davidson engine and all other (where should you pay attention with the upgrade's). Lucky or unluckly I brought the bike and I've noticed the modifications later. So, I discovered Inside the engine (cvo 110 cui, 2012) some S&S 570 cams. Now I'm riding like the former owner wanted....medium/high rpm range with 30-35 mpg... Keep up the good work! Greetings from Romania!
I told someone once.. If there was a book on all the intricacies of engine theory and assembly, “Camshafts” wouldn’t be a chapter in that book.. it would be the sequel to the book..
Hey man keep your knowledge coming. Next year after this abnormal time in our lives. Going to ride down to Georgia and see if you’re still up and going. Your explanation’s of a working HD Motors’s are very much appreciated.
I love your shows. They have clarified a lot of issues and giving me a good base of knowledge that over the past several years has been an issue. My bike was built at A Harley shop. SE 536 lift cam ( without a map available ). SE 10.50.1 high comp piston. Not sure what compression ratio is. Heads done JPsrcision Racing out of Quebec Canada. So a dyno to get it going and broke in from pro racing tunner . Coil some accell high whatever coil. So anyhow I cannot still believe they said it was tunned 3 Dynos by the end and the last one was like 6 hours using up to 6500 rpm they set no revlimiter .all through 2000 rpm the be tables were over a 100 and like 92 starting at 20 percent throttle , just bogged there explanation was well it's a mid to high rpm cam. I'm saying catalog reads from like 2000 or 2500 rpm. Anyways found the timing was way of in some areas like 1/1 the timing cleaned up the fuel. Now got an aei wide band 02 censor and gauge don't keep it on just for setting to read I don't have faith in the Harley tables. So lots of timing change and some fuel. At this point I'm surprised it is much what I was looking for. Before I had to wring the power out with rpm. And it did not seem to like sitting at any rpm lower timing more accurate fuel by the way 12.7 I figure they run it at 13 from idle all through to 25 percent throttle and then it dropped to 14.7 did not make sense to me so anywhere I'm outside of cruise 12.7 till wide open . Simplified for me and I cannot describe the difference in the ride. Alot of my achievement with this was guided n directed by your. videos.
Thanks for sharing the story Frank. Hate you had to deal with that...often it can be a process. Glad I was able to help you make it good. Excellent job sir.
People get hung up on dyno sheets , who cares if you make 150 HP and 150 TQ at 5000 , if the motor never goes there .. I just put a new cam chest in back in March , I'm the odd ball that doesn't change stuff "just to be changing" , but when I do have to change stuff then I upgrade to better and what I want ... I had my eyes on three cams ( 11 Road Glide ) and it came down to a buddy giving me a set of cams NIB for the cost of shipping .. Works for me .. SE255 , appears the torque curve is fairly flat , but you can tell you have power on tap always , idles much better , I used to be a cruise at 70-75 on the slab , bike breathes much better and actually is happier at 75-85 now .. Course with 72000 miles , the original breathers were shot .. And the primary cam shoe was not far from trashing the motor ..
@@jackiehoward3212 I know ewe ..... sup Jackie ?? you know yer woman Marlene is gonna be in Tennessee in a few weeks ?? I seen where you sissied out the other day .. Just take good care of Miss Faye's Roadie , send it to me and I will do the cams shoes this winter , oh send the title too ..
Wait, that was the basic overview? I'll definitely need to watch this a few times to absorb it. Thanks for the great info. I wish I lived closer to your shop.
As usual, Epic information Kevin. So appreciated! I am slowly upgrading my 2011 96 inch. I will finish Stage One, once my D&D 2 into 1 pipes arrive (caught in this Covid supply chain mess). I've already added a ThunderMax tuner to make sure each modification is properly supported. I had my crank runout checked before adding the Dark Horse Motor Sprocket (what a engine changer that was); But I did not check the cam side runout. I will check it before adding cams. I am just starting the cam education process. I can not see myself going any further that cams..... Passed that I would just consider a new bike..... Quite frankly, I don't think I will need more power or torque after cams. My riding style is "ride it like you stole it". I like fast acceleration up to the traffic speed.... But passed that I just cruise. If I tap into your expertise after more education on my part, I will buy the parts from you. Thanks again for this great video.
I got a 2013 FXDB and it has a completely stock 96" TC with just an S&S Stealth intake, Old style Screaming Eagle Tuner, and a set of short shot pipes. Yes I know those pipes are horrible but LOVE the look and sound. Ive dumped a ton of money into bike but now need more power. Problem is it still has less then 6,000 miles on the odometer. I was thinking just a set of cams? I live in North Idaho and only ride 6-8 months a year unfortunately. I dont ride a passenger ever. I like street light to street light and am almost NEVER on the freeways.
Actual info begins at 3:00 and then at least for me, by the end of the video, my brain is like scrambled eggs. I think I will invest in a Zero Electric Motorcycle.
Electric bike would be a good way to go low maintenance if you don't travel that far perfect but you have to work and back for some cruises you can always recharge your batteries while eating a hamburger taking a rest
When I made changes to my 2010 Heritage, I was going for the 103 kit. The dealer told me a larger cam would run best with the tuner (orange one) I had. I also have the SE air box and American Custom Exhaust slip ons that are stock but have been changed inside to almost straight through. I went with the SE 259e cams with a .570 lift over the 103 kit. I am satisfied with the performance.
All your videos are excellent Kevin,I can't wait till the next one 😎, been wanting the Zippers 468, bye the way I think you have cam intake & exhaust open & close wrong on your graph,great content just watched the 107" TC build
Dude can I just get you to sell me the cam I need 🤣 🤣. I know a lot about engines but not gone down the rabbit hole of everything you just said. Made my head hurt. I give you money, you give me cam
From your perspective, what do you love about it? That's kinda the point of the video...what you like specifically, may not be THE PERFECT cam for someone else. Thanks for sharing.
Alot of detail of cam values, but because of all the other factors involved, it really didnt help me decide on the Perfect Cam for my heavy touring M8, 107ci, but pointing to my need to listen to others with experiences with near the same set up.
Amazing video, but some of us have an added layer: Emissions. We can improve the engine to certain extent as emissions and dB on the tail pipe are limited by law. So how can we improve the engine while still be within the allowed limits?
Several exhaust manuf have released CARB and EPA compliant mufflers. The DBX series from Rinehart is just one example. You can run those exhaust, and with a proper tune, still meet your emissions standards.
Hi Kev , buddy you’ve got me hooked with the content you and that little red cup put out. I’d also like to know what cam you run inside that mind of yours because it really seems to crank out shed loads of calmly delivered credible information. Personally I think the Captain Morgan to Coke ratio must be part of the secret. Kev I’m running a 2014 Road King Classic with a full Bassani system. Bassani Header is mandrel bent, equal length, stepped header - 1 3/4 to 1 7/8 true duel system with Bassani DNT cans. Got a really nice deep sound. Heavy breather is the Screamin Eagle with K&N filter. This work was done by my local Harley dealership here on the Sunshine Coast in QLD Australia. Dyno done on completion gives me 103 ft lbs TQ & about 87 hp if I remember correctly. I owned a night road special for nearly ten years prior to this ride with similar mods and it went like greased cat shit and I loved it. Reason for mentioning this is that I ride the RK hard. I don’t burn out or thrash it but I do like to get to and from all the great little country pubs via all the great country back roads in quick time. I’d like to fit cam but their are so many choices I’m getting analysis paralysis. I want more torque because the poor old girl is a bit of a slug but not sure when in the rev range is the question, I agree totally with you that I’m in the group that doesn’t spend much time at the upper speed limits but I seem to keep the engine rpm up around 4 to 5k a lot of the time. I just like lively responsive engine rpm range and that seems to be the sweet spot for this bike. Something tells me that you might be able to suggest you’ve got a skunk works cam under your counter that might fit the bill. Regards Jon
Thanks Jon. Appreciate you watching. Be sure to sub if you havent. Lets see...on the Sunshine Coast...that's near Brisbane. Would your local HD dealer happen to be Morgan and Wacker? If so, next time youre in there, say hello to Malcom Martin for me. Great friend. Know all the guys at Rollies (John, Berto, and others), Adam and Julie at APL Perf, etc. Adam actually took me on a heli ride over Syd Harbor and surrounding. Was a great trip. At any rate...thanks for the kind words. Sounds like you'd really like to have a multi purpose bike there. Plenty up top but still need the low end grunt. One good option would be to swap gearing first and see if that gets you the pull youre after down low. From there, maybe a taller cam...S&S 585, RedShift has a couple of great options similar as well. Just my .02
I see quite a few owners on Harley forums who, after having a Stage II, come back disappointed at their bike's performance compared to before the upgrade. Many feel the performance doesn't equal the money they spent. I know you're in the business, but do you feel the money spent on a Stage II is worth it for the relatively minimal gains in torque and horsepower? Do you feel a Stage III would be a better "value"?
Tough question to answer. Performance, quality parts, and reliability is directly proportional to budget. Once that's determined, next is power expectation for dollar spent. The right cam, exhaust, and a really good tune can be a great value if the proper choices are made. Cams plus displacement increase is that middle road that i dont believe allows enough additional results to justify the additional cost. Now when you jump into headwork and a fully engineered package, that's when the magic really happens...but the budget has to grow. Great question.
I put s&s 583 easy start cam on my 96 dyna. I'm really pleased with the result. At 3000rpm you get a huge kick in the ass so funny. I competed some buddies with 103 dyna stage 1 and was faster one every rpm range. Not crazy faster but faster. For the price I spent (cam+work done by a buddy of mine so less expensive than stealership) i really enjoy it.
I’ve got a 1994 flhtcu with an se-2 cam with a high flow air cleaner and a stock exhaust. It feels like the exhaust is choking it out pretty good, is there a system (preferably on the quieter side) you would recommend? I appreciate your content and the hard work and time you guys put into them. Thanks
Sure...if you buy it from us ;). I'd be glad to help....we offer from all manufacturers because as i said, no one company makes the perfect cam for everyone. email me directly with the info. thanks.
another great video Kevin, what would you look for in a boosted application? how would you correctly choose a Turbo/ Supercharger camshaft? im guessing that intake velocities and filling the cylinders would be less of a thing.. but thats only me guessing. Id love to see some content on boosted applications for example a twin cam 96" ;-) is it ok to go to 107 with boost? safer to leave at 96" as theres more gasket?, many boosted bikes out there nowadays. . anyway thanks again for the great videos and hello from Down under 🙂
I went from se203 to a 21n to do hydraulic cam plate. Didn’t know bike had 203s until I pulled it apart. 21n made the bike slower! Workin on a tw6-6r install now bike ran mint w 203s but tensioners were smoked
Hello, I am a big fan of your work. I have a 2012 Softail with the 103 engine, looking for the best bang for the buck cam upgrade. My riding style is fast and hard but never more than 5000 rpm. Not trying to blow it up lol. I've had it since new and have tried to take my Best to take good care of it. I prefer the look of the Bassani 34" fishtail true dule exhaust, yes I know it is not the best thing for power. I also run the k&n air cleaner with no cover, I spent most of the miles never even getting up to more than 4000 rpm but have recently been trying to get a little higher up there but I am naturally concerned with the health of the engine. I would like it ask you please for a recommendation for the best drop in cam for me. I've never been one to redline or abuse my bike but I do like to get my thrill below 80mph. I know well that you have plenty of paying customers and if you can't answer I would understand. Disabled veteran on a limited income and and although that's not an excuse just the facts of it. This machine is my lifeline and the health benefits are amazing. Thank you in advance either way and I will continue to be a fan even if you can't get back to me, you make more sense than most people I can find and I respect you for what you do. briancolburn@yahoo.com
585 or 551 cam for 2013 - twincam 103 touring if purpose is good low end pull and no targets in the future for any other hot rod upgrades. I couldn't find answer for it in the video.
Amazing video as always Kevin! It´s time for me to mount a new set of bolt in performance cams into my FXSB 103. I´m riding in the higher rev range when I want my power to really be noticeable, so I´m wondering what cam you´d suggest based on this information? I combine this with a TBR Comp-S 2 into 1 exhaust together with a custom map on dyno and an open air filter! Thanks again Kevin!
I put a 131" Stage 4 Kit in my 2019 Ultra with D& D Billet Cat Exhaust. During Daytona Bike week I talked to T-man about his Cams. Hence I replaced my Zippers Redshift 468 Cam with his TMP-2652 cam with 515 lift. Hoping I made the right choice. I ride 2-up a lot. Your thoughts?
Love this channel, I have a 2021 Road Glide, 107 M8, completely stock (for now)....the only mods I plan on doing are full exhaust with air cleaner and a tuner on the dyno. I would like to do a mild cam. I’ve read that the S&S 465 is a good cam, especially for the touring bikes. Do you agree? Would I have to change any other engine components to safely run this cam? What would you recommend for a cam? (Not looking to build a race bike, just something with a little more power. Reliability is my first concern). Also, what is your opinion on the SE torque cam? Vs the S&S 465 cam? Thanks.
Kevin I have a 2014 ultra limited water cooled hats what can I do to get the most power out of that motor I generally run short short shift 25 to 4500 RPM 90% of my time I run solo
a lot of power can be had out of a twin cam....and we have many many options for you...cam, build, etc. Understand we can build you a 300 plus horsepower Twin Cam....but that's more than most need. So when you say the "most", i need to understand more about what you mean by that. Feel free to shoot me an email. If youre interested in a build, or other parts options, wed be happy to help you. tech@protwin.com
I have a stock 2005 88 cubic inch want to put cams and a good head but leave the cylinders along what would be the best cam for that guys are telling me to go with the triple fives or seven wood cans light for the torque range to be maybe $1,500 up to five grand what's your opinion on what can I should run
Kevin is a cam upgrade on a Harley big twin with a stock crank a bad idea? Can the Harley crank take the upgraded power ? In your opinion would a after market crank be a better start before any upgrades on a stock Harley 96” big twin for more power ?
not a problem with that at call. a cam wont cause the issue...but make sure to check runout when you get in there. you dont have to replace the crank. many are good and run for years. check it though before investing bit in HP.
I'm not a professional but I watched a Kevin Baxter video last night. All that being said...can you recommend the best cam for a guy with a stock 107 M8 who likes to get on it every once in awhile? I like the twisties as well as opening up on long stretches. TIA
Kevin, I'm confused regarding your "Lobe Separation Angle" graphic? It shows "Intake Closes" twice and doesn't show "Intake Opens"? I was expecting the intake to open in the upper right-hand quadrant of the graphic? Tom
I am very interested in the S&S 475 cam for my 2017 RG Ultra. My question is do you recommend just changing the cam shaft with push rods and lifters or change the entire cam chest, New cam plate and oil pump. Thank you
depends on your year, condition of your plate and pump, etc. I dont just flat out recommend parts unless they are required or various other reasons. One, is largely based on your peace of mind. If youre interested, shoot us an email to sales@protwin.com and we can reach out to you. Thanks.
Great video and excellent explanation!! I’ve mostly dealt with car cams for 30+ years and still learning things!!! Curious on your opinion, I have a 08 FatBoy 13k miles, Arlen Ness Big Sucker, Bad Dad 2 into 1 exhaust, currently has a DJ PC-V (will be looking to change to a PowerVision) and upgrading the compensator to the DarkHorse Comp. I mostly ride solo (200 lb), we have hills but mostly flatter kind of riding in the southern North East. Also normally ride in the 2500-5000 rpm range with an occasional “let her eat” kind of riding. I have been looking at the Andrews 48H but wasn’t sure. Any sort of guidance would be great, and once I figure this out I’ll be in touch to order some parts, but will have to order parts as money is available for it. (Daughter in college) thanks again. I almost forgot I do have a batwing fairing and hard-bags on the bike.
That is a fantastic cam if your goal is the lowest torque you can get. If you havent, take a look at my latest video on M8 cams. I compare cams to help folks better understand the numbers. When you look at the specs of that cam, you'll understand why it makes torque so low. Look forward to hearing from you when youre ready.
I installed the S&S 510c cam in my 2002 Dyna, along with the S&S 97ci kit and had my heads ported, polished and decked and it’s a fun bike to ride. I’m thinking of using the S&S 509c cam in a stock 2005 Heritage softail. How will this cam compare? I has a softail with an Andrews 44 cam in the past but it felt more like a higher revving cam.
Depends largely on how the cam responds to the heads. Its a system. But...if you take the specs and compare them, along with the overview I gave, you will understand how the change in specs will affect what you have now, in general.
Excellent video Kevin! Question, how much does having the heads flowed effect cam choice? I think they go hand in hand as in you should do one with the other. I have a 2019 Limited, a 1000llb bike and think I should concentrate on the lower rpm range. Whats the best cam choice for my bike if i have the heads flowed? Thanks man! You do an awesome job, keem'em coming!
Tremendously. Heads and cam need to work together and should be chosen together. There is no best...and there are many ways heads can be done. Whoever you choose to do your heads, us or others, should be the one to recommend the cam. Low to mid range torque for touring. Thanks!
I've got a 2020 Breakout 114 with a Wood 22x cam. Torque isn't the word. It raises and evens out the idle somewhat and is a torque monster. It's just fine to cruise on the highway or putt around town and has instant power when you need it.
Hey, I just caught your video explaining cams. I have a stock 2003 TC88 FLHRCI 31k. Chain tensioner pads caught just in time. Not doing the up grade just yet. Want to go with Zipper's in the future but for now replacing tensioners, S&S quickies, HLJ 2313SE lifters, DS "Daytona" performance oil pump, new analog oil PSI gauge. and trying to decide Cams or no cams. I know there are limitations for my stock bike and found the "night train" site with a dizzing awray of cams to review. it has highly suggested to run no more than .250 duration and .510 lift cam in my stock set up. trying to narrow down and am in the range of Andrews TW37, or 37B, I ride the mountains of NC. Not going to the strip any time soon wanted to know if that cam would be a good bolt in fit for my bike with just a bit more pep. Thanks for any in put.
Stock 2015 FLHXS 103 with SE super tuner Pro , SE heavy breather and 4" Rineharts with decatted head pipe....your thoughts on the T Man 555 torqster cam I ride mostly solo and like the feel of mid range power not so much off the clutch .
Hey Kevin, great video as always. I have a 2020 Street Glide Special 114ci. with S&S Power Tune Dual Header, SVT boneshakers slip-ons, Arlen Ness Big mouth Air Cleaner, S&S 475c Cam, oil pump, plate, inner bearing, pushrods, lifters, and Thundermax tuner. This week I upgraded my primary with a Darkhorse compensator sprocket, Trask clutch basket, Hayden M6 tensioner, and Rekluse TorqueDrive clutch. Everything is running great, however I can't go to neutral. She is up and down shifting fine to every except for neutral. The Rekluse tech said to run she for 500 miles to break-in the new clutch, and it should fine neutral when it break-in. 1. What is your advice on this? 2. Will the Darkhorse compensator sprocket tear up my stock crankshaft, since it doesn't have a spring? Thanks!! Rube
You have a very good list of parts there. Im assuming you have a hydro clutch...which doesnt allow adjustment. That is one reason i run the clutches i do...and i'll explain. First take a look at this video th-cam.com/video/EHSiTmTVnu8/w-d-xo.html In short, it comes down to maximum pressure plate travel, and stack height of the clutch. You must have .060 pressure plate travel on a cruise drive to fully release the clutch. Stock...it's right at that already. If the stack height of the clutch pack is even slightly too thick, that travel, or clearance, is reduced, which will cause your clutch plates to drag making it hard to find N. This is why im not a fan of clutch packs that add plates. One other thing to look at...if you are running fat grips, or and adjustable lever, or covers over your lever, this will reduce clutch travel as well. Hope this helps.
@@KevinBaxter Alright brother!!!! So I have Arlen Ness grips and Arlen Ness levers, and I looked at my clutch lever and grip, and it turned out that lever at the side closed to the controls was hitting the grip 3/16 of an inch too early. So I took my grinder to it, and shaved off enough to get the entire clutch lever travel. THANKS A LOT!!!!! PROBLEM FIXED, Now I find neutral with ease. THANKS!!!!
Glad I found your channel tons of great info. I have a 09 night train what cam would you recommend for street / touring I'm in new Mexico we have mountains all over my bike has stock throttle body a Arlen Ness velocity intake, V&H pipes, stock heads, cobra auto tune. Down the road I may put a 110 kit in so possiblity a cam that could work well with both. Not looking to race just a improvement over stock for some good street torque. In the past I installed Andrews 54H cames in my Electra glide pretty much same set up and they were fantastic in that heavy touring bike and how I rode not are if they would also be a good choice for a Softail. I was interested in the easy start cams from s&s as they sell complete install kits with plates and pump as well. Any infor would be great since like you said there are so many options it can get confusing. Thanks
I’m waiting on my S&S 509c cam chest kit to be delivered now. After my new cams are installed what do I have to do in the way of tuning the bike before it can be ridden regularly? I already have the stage 1 intake and the EFI upload that Harley recommended. Time, money and location will be a factor in getting a full professional tune.
What do you recommend for a 2018 road glide only modification done was a Trask nasty bastard 2-1 exhaust Would you say : 465 s&s Fueling or Something els ?
I have a stock 99 road king 88 ci. Carbie. I’ve chose a S&S 509 only goi to have slip ons and maybe air filter .. was this a good choice for around town and some highway riding. I just thought a s&s 510 was to hot for me. Thanks. From Australia
New Subscriber here. Your videos have so much information, I had to get in on it. I've read that the TTS 100 cam can give some instant grunt in a M8. Have you had any experience with that cam?
I went with the screaming eagle 462 power cam, on my 2o21 new road glide limited and its putting out great Torque at 116.5 at 3500 rpms and getting 102.5 power, se tuner, and vance n hines power duals, with rinehart slip ons that was free, my goal was to bring up the horsepower on a stage 2 build, as a bonus I'm getting great early on torque, seen many posting to get the torque cam, so I went with power cam, and completely no regrets, and the sound is amazing too
Still confused 🤔😆 . Built an engine for my 2010 RK ,my first one. Standard 103 with auto decompression releases. 103 heads plunge cut and port matched S&S 650” springs 58mm CVO throttle body 5.3 g/s screaming eagle injectors 103 factory barrels bored to 107 Wiseco Trekker pistons and rings 10.5-1 compression Andrews 54H cams S&S crank and flywheels Fueling cam plate and HV oil pump Fueling HV lifters Fueling hydraulic tensioners S&S adjustable pushrods Vance & Hines true duels exhaust . Got good torque from 1800rpm up to 113ftlb at about 3500. Horsepower around 103. Can I get better torque by changing my cam? Recommendation on better torque cam for my build ? Most of my riding is corners , hills or 2up. Thanks
I actually have v&h power duels with screaming eagle slip on’s , sorry . Was recommended tw555 woods cams . My aim is low end torque and reliability. The wife and I often take off on long weekend trips and have a 15 day trip coming up in a few months down to Tasmania from QLD . A few thousand ks.
Kevin, I had a Zippers 468 RS cam installed on my 107 Heritage. It’s tuned with a Powervision Tuner from a very reputable guy tuning at the HD dealership. Stock I was getting around 42mpg and now I’m barely getting 32mpg. Is this normal for a Zippers cam?

My favorite term I use in engine building is " just because you can doesn't mean you should"
My other favorite is "sometimes less is more".
Very well said Kevin, couldn't have explained it better. Yes, I understood everything you explained - this is why back in the 90's I conquered all other dragbikes! Played with valve overlap (staggered) until it produced the best power for my engine. Ran 8.64's back then. Cheers.
Absolutely a great and direct video. I can't tell you how many customers drop in wanting a cam their buddy has due to a Dyno sheets max numbers at WOT and 6500 RPM. I suggest they ride their buddies bike for 100 miles and be honest about what they feel. They usually come back and tell me their stock bike was actually more enjoyable than the "tricked out" one with the exception of a WOT sprint. I then begin to discuss a realistic cam choice for their engine and bike combination and their realistic riding style.
Thank you Max. People often ask me how they can know if the advice they are getting is good advice. My answer...."you'll know by the quality and number of questions they ask you before they give the advice." Good on you sir!
@@KevinBaxter That is an excellent statement to live by. When I use to manage a fleet if equipment....my superior mentioned to me more than once that some of the operators complained about me asking too many questions....as if they were being interrogated....ha ha. But seriously....I really appreciate your outlook and style. Thank you.
@@KevinBaxter Oh..BTW.....I truly hope the questions I have asked you have been of quality!!!!
Always sir. Great questions that show genuine concern for your customers. That's classy.
Use general motors newer V8 logic small cam massive cylinder heads. Then you can cam accordingly to suit where you need it! Never chase chop chop chop
Been building and repairing engines of all kinds for over 20 years and I learned several things about choosing cams my old school teachers may have tried to teach me but didn't sink in. Thanks Kevin I appreciate it very much
And those things are.......?
great schooling on cams and cam selection.i bought a new roadking in 2002 still have it.it ran like a slug, it always felt like it was chocking. I put an air filter and backing plate, Harley freeflow mufflers all screaming eagle and a dealership download still not as ballsy as my 1977 shovelhead. then on to a stage 2, 95"kit 203 cams, and a download.very disappointed in the performance. years later I put a fueling cam (525) lift, oil pump, cam plate, gear-driven cams, lifters. adjustable pushrods and, and a Daytona twin-tec 2 tuner. now it runs as it should, I downloaded the tune myself. my point here is if I had seen your video 10 years ago I would have saved some $$ and aggravation, never too late to learn even at 65 yr old. thank you, keep the info coming!
thank you Martin.
The magical world of bump sticks. Excellent video.
Thank you my friend.
2018 FLTRU with 74,000kms. on it. Went with a SE Power Cam. Works great for me as I do 99.9% of my riding on the highway. Also SE 4" slips ons and an upgraded oil pump, after market airflow. It's awesome on the highway, anything above 3000 rpm it takes off like crazy.
Kevin, as a mechanic (autos) for close to 40 years, I love your videos. Always learn something. Always believed in synthetics, after your video switched to Amsoil. This is another good one! Choose the cam for your riding style! Not your buddy’s Dyno printout!
Thank you so much Joe. I appreciate your kind words. Great statement!
Great video Kevin,, this has to be the best explanation of what a cam is and how it works and why, hands down outstanding work lad. If this is the basics, I've got some studying to do before the intermediate lesson.
This is a dominating topic on so many forums. Most look at peak numbers and how it sounds at idle and end up unhappy with the results. I'll be the first to admit. I almost made the wrong decision when choosing a cam. Thankfully I had someone who asked me all the right questions before I spent hundreds of dollars on the incorrect parts. People, please trust the advice of professionals like Kevin Baxter and get it done right the first time.
Thanks for the kind words Kerry. Glad you had that available to you. Do i know the fella who asked you those questions? ;)
@@KevinBaxter You sure do...
My promise to the viewers of the channel has always been to say when something is good...regardless of brand. That includes the folks that work on these things if i can personally vouch for them. I'm not surprised he asked you the right questions..proves what I knew. Rob Swartz at Rob's Dyno in Gardner, MA knows what he's doing. If you're in his area, check him out.
With the almost infinite number of cams available choosing the right one, or two for twin cams can be overwhelming. I usually just ask where do you want your power to kick in and go from there. Fortunately most of the manufacturers are good at giving a fair description of how their different cams perform at different rpm ranges. As for which manufacturer to go with sometimes that just comes down to personal preference and past experience.
I have a '19 ultra and did an SE Torque Cam as soon as i bought it for a 7k mile trip out west. I've been very pleased with it. I've since replaced my oil pump and cam plate (for piece of mind) with an s&s because of the HD oil pump issues but left the SE cam in because honestly its pretty damn good. I know people will have an issue with that but i have TONS of torque with the SE cam and i really dont need any more performance out of my 114 highway cruiser!
I also went with the SE cam, but went with the 462 power cam, max torque is 116.5 at 3500 rpms, power is at 102.5, , the voiding the factory warranty and getting good power n torque, while running a vance n hines power duals and the free Rinehart slip ons, a nice simple stage 2 build on the 114 is all I need n more riding 2 up just swapped to a new road glide limited 2021 from a 2014 ultra classis 103 with just a stage 1 with all vance n hines pipes, had plenty of power n torque with that bike 2 riding 2 up , in rolling hills
The more that I learn the more I know that I don't know. I have a year before I have the bike payed off anyway. Thanks for sharing. I kind of understood.
That was a great refresher. I remember geeking out over stuff like that in Hot Rod, Chevy High Performance, and Car Craft when I was a kid, but I had forgotten some of those details. So this was a good watch, since I've been looking at cams for my old Evo.
Glad you enjoyed it. thanks.
This is the very best explanation of how cam shafts work. The diagram really helped explain a lot to.
Great video mate.
Thank you. 👌
Great video Kevin, lots of great info. Thanks for taking the time to share. Cheers
Glad it was helpful! Thanks for following along and for the kind words.
Great information Kevin. I am getting a better understanding of the overall importance of the collective relationship between all the other working components along with the cams for my V-Twin. Thanks again. Great content.
Thank you very much Kevin for explaining all this details of Harley Davidson engine and all other (where should you pay attention with the upgrade's). Lucky or unluckly I brought the bike and I've noticed the modifications later. So, I discovered Inside the engine (cvo 110 cui, 2012) some S&S 570 cams. Now I'm riding like the former owner wanted....medium/high rpm range with 30-35 mpg...
Keep up the good work! Greetings from Romania!
thanks for the comment and for following along. sounds like a great bike. Never been to Romania...but would love to. Cheers!!
I told someone once.. If there was a book on all the intricacies of engine theory and assembly, “Camshafts” wouldn’t be a chapter in that book.. it would be the sequel to the book..
My head is spinning, but this was a very informative video. Thanks.
Hey man keep your knowledge coming. Next year after this abnormal time in our lives. Going to ride down to Georgia and see if you’re still up and going. Your explanation’s of a working HD Motors’s are very much appreciated.
I hope to be...don't plan on going anywhere. Thanks for the kind words.
I'm more confused, then before I watched your video.
I love your shows.
They have clarified a lot of issues and giving me a good base of knowledge that over the past several years has been an issue.
My bike was built at A Harley shop. SE 536 lift cam ( without a map available ).
SE 10.50.1 high comp piston. Not sure what compression ratio is.
Heads done JPsrcision Racing out of Quebec Canada.
So a dyno to get it going and broke in from pro racing tunner .
Coil some accell high whatever coil.
So anyhow I cannot still believe they said it was tunned 3 Dynos by the end and the last one was like 6 hours using up to 6500 rpm they set no revlimiter .all through 2000 rpm the be tables were over a 100 and like 92 starting at 20 percent throttle , just bogged there explanation was well it's a mid to high rpm cam. I'm saying catalog reads from like 2000 or 2500 rpm.
Anyways found the timing was way of in some areas like 1/1 the timing cleaned up the fuel.
Now got an aei wide band 02 censor and gauge don't keep it on just for setting to read I don't have faith in the Harley tables.
So lots of timing change and some fuel. At this point I'm surprised it is much what I was looking for. Before I had to wring the power out with rpm. And it did not seem to like sitting at any rpm lower timing more accurate fuel by the way 12.7 I figure they run it at 13 from idle all through to 25 percent throttle and then it dropped to 14.7 did not make sense to me so anywhere I'm outside of cruise 12.7 till wide open .
Simplified for me and I cannot describe the difference in the ride.
Alot of my achievement with this was guided n directed by your. videos.
Thanks for sharing the story Frank. Hate you had to deal with that...often it can be a process. Glad I was able to help you make it good. Excellent job sir.
I just got a 2020 Road King Special and am sold on the S&S 475C. Appreciated your in depth wisdom on this video. Subbed :)
Awesome! Thank you!
People get hung up on dyno sheets , who cares if you make 150 HP and 150 TQ at 5000 , if the motor never goes there .. I just put a new cam chest in back in March , I'm the odd ball that doesn't change stuff "just to be changing" , but when I do have to change stuff then I upgrade to better and what I want ... I had my eyes on three cams ( 11 Road Glide ) and it came down to a buddy giving me a set of cams NIB for the cost of shipping .. Works for me .. SE255 , appears the torque curve is fairly flat , but you can tell you have power on tap always , idles much better , I used to be a cruise at 70-75 on the slab , bike breathes much better and actually is happier at 75-85 now .. Course with 72000 miles , the original breathers were shot .. And the primary cam shoe was not far from trashing the motor ..
All too correct Jack. Thanks for the comment. Glad they worked out for you sir!
JtB ; you purdy dern smart for an Bama boy!!!! LOL :-) Your Yankee friend Jacksprat haha
@@jackiehoward3212 I know ewe ..... sup Jackie ?? you know yer woman Marlene is gonna be in Tennessee in a few weeks ?? I seen where you sissied out the other day .. Just take good care of Miss Faye's Roadie , send it to me and I will do the cams shoes this winter , oh send the title too ..
Wait, that was the basic overview? I'll definitely need to watch this a few times to absorb it. Thanks for the great info. I wish I lived closer to your shop.
At a suggestion from a knowledgeable individual I met in Laughlin I bought and put in Crusher 375’s. They’re in a 2016 Wethead,
As usual, Epic information Kevin. So appreciated! I am slowly upgrading my 2011 96 inch. I will finish Stage One, once my D&D 2 into 1 pipes arrive (caught in this Covid supply chain mess). I've already added a ThunderMax tuner to make sure each modification is properly supported. I had my crank runout checked before adding the Dark Horse Motor Sprocket (what a engine changer that was); But I did not check the cam side runout. I will check it before adding cams. I am just starting the cam education process. I can not see myself going any further that cams..... Passed that I would just consider a new bike..... Quite frankly, I don't think I will need more power or torque after cams. My riding style is "ride it like you stole it". I like fast acceleration up to the traffic speed.... But passed that I just cruise. If I tap into your expertise after more education on my part, I will buy the parts from you. Thanks again for this great video.
Great video, S&S 475G helps power my 2018 streetglide 114 big bore stage 4
That's a great choice if it works for you! Thank you sir.
I got a 2013 FXDB and it has a completely stock 96" TC with just an S&S Stealth intake, Old style Screaming Eagle Tuner, and a set of short shot pipes. Yes I know those pipes are horrible but LOVE the look and sound. Ive dumped a ton of money into bike but now need more power. Problem is it still has less then 6,000 miles on the odometer. I was thinking just a set of cams? I live in North Idaho and only ride 6-8 months a year unfortunately. I dont ride a passenger ever. I like street light to street light and am almost NEVER on the freeways.
I'll be glad to help you John. If youll shoot me an email, kevin@protwin.com, i can help you get set up for the next stage. Thanks.
@@KevinBaxter THANK YOU! I Will!
Actual info begins at 3:00 and then at least for me, by the end of the video, my brain is like scrambled eggs. I think I will invest in a Zero Electric Motorcycle.
Electric bike would be a good way to go low maintenance if you don't travel that far perfect but you have to work and back for some cruises you can always recharge your batteries while eating a hamburger taking a rest
Awesome job explaining this really helpful
Glad you think so! Thanks.
When I made changes to my 2010 Heritage, I was going for the 103 kit. The dealer told me a larger cam would run best with the tuner (orange one) I had. I also have the SE air box and American Custom Exhaust slip ons that are stock but have been changed inside to almost straight through. I went with the SE 259e cams with a .570 lift over the 103 kit. I am satisfied with the performance.
What is the best cam for an 88 cubic inch Harley Davidson motor with 19,000 mi on it to get the best performance possible
All your videos are excellent Kevin,I can't wait till the next one 😎, been wanting the Zippers 468, bye the way I think you have cam intake & exhaust open & close wrong on your graph,great content just watched the 107" TC build
I'll have a look at that...thank you. Appreciate you watching!
Dude can I just get you to sell me the cam I need 🤣 🤣. I know a lot about engines but not gone down the rabbit hole of everything you just said. Made my head hurt. I give you money, you give me cam
sure. shoot us an email and we can get you in the right one. jason@protwin.com
For these M8 Harley’s the new June 2020 Wood performance 22-xe cam is unreal!
From your perspective, what do you love about it? That's kinda the point of the video...what you like specifically, may not be THE PERFECT cam for someone else. Thanks for sharing.
Alot of detail of cam values, but because of all the other factors involved, it really didnt help me decide on the Perfect Cam for my heavy touring M8, 107ci, but pointing to my need to listen to others with experiences with near the same set up.
Amazing video, but some of us have an added layer: Emissions. We can improve the engine to certain extent as emissions and dB on the tail pipe are limited by law. So how can we improve the engine while still be within the allowed limits?
Several exhaust manuf have released CARB and EPA compliant mufflers. The DBX series from Rinehart is just one example. You can run those exhaust, and with a proper tune, still meet your emissions standards.
Hi Kev , buddy you’ve got me hooked with the content you and that little red cup put out. I’d also like to know what cam you run inside that mind of yours because it really seems to crank out shed loads of calmly delivered credible information. Personally I think the Captain Morgan to Coke ratio must be part of the secret. Kev I’m running a 2014 Road King Classic with a full Bassani system. Bassani Header is mandrel bent, equal length, stepped header - 1 3/4 to 1 7/8 true duel system with Bassani DNT cans. Got a really nice deep sound. Heavy breather is the Screamin Eagle with K&N filter. This work was done by my local Harley dealership here on the Sunshine Coast in QLD Australia. Dyno done on completion gives me 103 ft lbs TQ & about 87 hp if I remember correctly. I owned a night road special for nearly ten years prior to this ride with similar mods and it went like greased cat shit and I loved it. Reason for mentioning this is that I ride the RK hard. I don’t burn out or thrash it but I do like to get to and from all the great little country pubs via all the great country back roads in quick time. I’d like to fit cam but their are so many choices I’m getting analysis paralysis. I want more torque because the poor old girl is a bit of a slug but not sure when in the rev range is the question, I agree totally with you that I’m in the group that doesn’t spend much time at the upper speed limits but I seem to keep the engine rpm up around 4 to 5k a lot of the time. I just like lively responsive engine rpm range and that seems to be the sweet spot for this bike. Something tells me that you might be able to suggest you’ve got a skunk works cam under your counter that might fit the bill. Regards Jon
Thanks Jon. Appreciate you watching. Be sure to sub if you havent. Lets see...on the Sunshine Coast...that's near Brisbane. Would your local HD dealer happen to be Morgan and Wacker? If so, next time youre in there, say hello to Malcom Martin for me. Great friend. Know all the guys at Rollies (John, Berto, and others), Adam and Julie at APL Perf, etc. Adam actually took me on a heli ride over Syd Harbor and surrounding. Was a great trip. At any rate...thanks for the kind words. Sounds like you'd really like to have a multi purpose bike there. Plenty up top but still need the low end grunt. One good option would be to swap gearing first and see if that gets you the pull youre after down low. From there, maybe a taller cam...S&S 585, RedShift has a couple of great options similar as well. Just my .02
I see quite a few owners on Harley forums who, after having a Stage II, come back disappointed at their bike's performance compared to before the upgrade. Many feel the performance doesn't equal the money they spent. I know you're in the business, but do you feel the money spent on a Stage II is worth it for the relatively minimal gains in torque and horsepower? Do you feel a Stage III would be a better "value"?
Tough question to answer. Performance, quality parts, and reliability is directly proportional to budget. Once that's determined, next is power expectation for dollar spent. The right cam, exhaust, and a really good tune can be a great value if the proper choices are made. Cams plus displacement increase is that middle road that i dont believe allows enough additional results to justify the additional cost. Now when you jump into headwork and a fully engineered package, that's when the magic really happens...but the budget has to grow. Great question.
I put s&s 583 easy start cam on my 96 dyna. I'm really pleased with the result. At 3000rpm you get a huge kick in the ass so funny. I competed some buddies with 103 dyna stage 1 and was faster one every rpm range. Not crazy faster but faster. For the price I spent (cam+work done by a buddy of mine so less expensive than stealership) i really enjoy it.
“How to choose the right cam….”
“Decide for yourself”
Thanks man lol
My head just exploded! 🤯
Cam examples would of been nice. Great info as always
Here for the algorithm!! Thanks a lot Kev
That intro music is what scotty kilmer uses.
I’ve got a 1994 flhtcu with an se-2 cam with a high flow air cleaner and a stock exhaust. It feels like the exhaust is choking it out pretty good, is there a system (preferably on the quieter side) you would recommend? I appreciate your content and the hard work and time you guys put into them. Thanks
I'm gonna throw this out there Kevin. If I gave all my bikes present specs and what I expected from it, would you recommend a cam?
Sure...if you buy it from us ;). I'd be glad to help....we offer from all manufacturers because as i said, no one company makes the perfect cam for everyone. email me directly with the info. thanks.
2001 Duce 1450cc I have good air box and muffler ,I'm looking for low rpm thump-er my bike runs ok but idle is weak top end is good.
If youre interested in a cam, shoot me an email at kevin@protwin.com or go here and I can see what we come up with protwin.com/camselector.aspx
another great video Kevin, what would you look for in a boosted application? how would you correctly choose a Turbo/ Supercharger camshaft? im guessing that intake velocities and filling the cylinders would be less of a thing.. but thats only me guessing. Id love to see some content on boosted applications for example a twin cam 96" ;-) is it ok to go to 107 with boost? safer to leave at 96" as theres more gasket?, many boosted bikes out there nowadays. . anyway thanks again for the great videos and hello from Down under 🙂
I run Andrews tw21 in my stock ultra twin cam 88 It’s one cam above stock and will really wake up that stock motor
That's a good choice.
I went from se203 to a 21n to do hydraulic cam plate. Didn’t know bike had 203s until I pulled it apart. 21n made the bike slower! Workin on a tw6-6r install now bike ran mint w 203s but tensioners were smoked
Hey Kevin. I got a 20 rg with 107. I’m a big guy and ride 2 up fairly often I’d love to find a fun torque cam
shoot me an email kevin@protwin.com We can toss around a few specs and get you in the right one for you.
Hello, I am a big fan of your work.
I have a 2012 Softail with the 103 engine, looking for the best bang for the buck cam upgrade.
My riding style is fast and hard but never more than 5000 rpm. Not trying to blow it up lol.
I've had it since new and have tried to take my Best to take good care of it.
I prefer the look of the Bassani 34" fishtail true dule exhaust, yes I know it is not the best thing for power.
I also run the k&n air cleaner with no cover, I spent most of the miles never even getting up to more than 4000 rpm but have recently been trying to get a little higher up there but I am naturally concerned with the health of the engine.
I would like it ask you please for a recommendation for the best drop in cam for me. I've never been one to redline or abuse my bike but I do like to get my thrill below 80mph.
I know well that you have plenty of paying customers and if you can't answer I would understand.
Disabled veteran on a limited income and and although that's not an excuse just the facts of it.
This machine is my lifeline and the health benefits are amazing.
Thank you in advance either way and I will continue to be a fan even if you can't get back to me, you make more sense than most people I can find and I respect you for what you do.

585 or 551 cam for 2013 - twincam 103 touring if purpose is good low end pull and no targets in the future for any other hot rod upgrades. I couldn't find answer for it in the video.
Amazing video as always Kevin! It´s time for me to mount a new set of bolt in performance cams into my FXSB 103. I´m riding in the higher rev range when I want my power to really be noticeable, so I´m wondering what cam you´d suggest based on this information? I combine this with a TBR Comp-S 2 into 1 exhaust together with a custom map on dyno and an open air filter! Thanks again Kevin!
Fantastic vid. 👍🏽
I put a 131" Stage 4 Kit in my 2019 Ultra with D& D Billet Cat Exhaust. During Daytona Bike week I talked to T-man about his Cams. Hence I replaced my Zippers Redshift 468 Cam with his TMP-2652 cam with 515 lift. Hoping I made the right choice. I ride 2-up a lot. Your thoughts?
John...this is a great question. One I'll use to do a follow up video later this week. Thanks for the post!
I cant find that cam anywhere on Tmans website. Can you send me the link or the specs?
I put in my 95 cu in a HQ-0034G when everyone else was putting in really big cams around me. They all had problems with idle. Go figure.
Go figure is right. That's a good cam. I know it very well.
Love this channel, I have a 2021 Road Glide, 107 M8, completely stock (for now)....the only mods I plan on doing are full exhaust with air cleaner and a tuner on the dyno. I would like to do a mild cam. I’ve read that the S&S 465 is a good cam, especially for the touring bikes. Do you agree? Would I have to change any other engine components to safely run this cam? What would you recommend for a cam? (Not looking to build a race bike, just something with a little more power. Reliability is my first concern). Also, what is your opinion on the SE torque cam? Vs the S&S 465 cam? Thanks.
S&S is the way to go over se cams.

Kevin I have a 2014 ultra limited water cooled hats what can I do to get the most power out of that motor I generally run short short shift 25 to 4500 RPM 90% of my time I run solo
a lot of power can be had out of a twin cam....and we have many many options for you...cam, build, etc. Understand we can build you a 300 plus horsepower Twin Cam....but that's more than most need. So when you say the "most", i need to understand more about what you mean by that. Feel free to shoot me an email. If youre interested in a build, or other parts options, wed be happy to help you. tech@protwin.com
Well said Kev... 👍🏻👍🏻👍🏻🤔
I have a stock 2005 88 cubic inch want to put cams and a good head but leave the cylinders along what would be the best cam for that guys are telling me to go with the triple fives or seven wood cans light for the torque range to be maybe $1,500 up to five grand what's your opinion on what can I should run
Great video!!
Kevin is a cam upgrade on a Harley big twin with a stock crank a bad idea? Can the Harley crank take the upgraded power ? In your opinion would a after market crank be a better start before any upgrades on a stock Harley 96” big twin for more power ?
not a problem with that at call. a cam wont cause the issue...but make sure to check runout when you get in there. you dont have to replace the crank. many are good and run for years. check it though before investing bit in HP.
Greetings from Brazil! Don't tread on me!
I'm not a professional but I watched a Kevin Baxter video last night. All that being said...can you recommend the best cam for a guy with a stock 107 M8 who likes to get on it every once in awhile? I like the twisties as well as opening up on long stretches. TIA
Great information......Thanks.
Kevin, I'm confused regarding your "Lobe Separation Angle" graphic? It shows "Intake Closes" twice and doesn't show "Intake Opens"? I was expecting the intake to open in the upper right-hand quadrant of the graphic? Tom
Thanks Kevin
Youre welcome! Thank you.
sounds like to me, just leave it stock sometimes that's the best way to go
How about just buy a bike from a manufacturer that engineers it properly from the factory?
Yeah I'm going to have to call you Kevin. Because you just gave me too much information and I'm confused lol
best way to reach me is thru email. kevin@protwin.com and please be patient. i get a lot of them.
Nice upload!!
Thank you! Cheers!
Good tips and info.
I am very interested in the S&S 475 cam for my 2017 RG Ultra. My question is do you recommend just changing the cam shaft with push rods and lifters or change the entire cam chest, New cam plate and oil pump. Thank you
depends on your year, condition of your plate and pump, etc. I dont just flat out recommend parts unless they are required or various other reasons. One, is largely based on your peace of mind. If youre interested, shoot us an email to sales@protwin.com and we can reach out to you. Thanks.
Very interesting! Thanks.👍
Glad you enjoyed it. THank you.
My question is what's a good cam operating in the 1500-3000 rpm range for more torque v-twin
So many choices out there....look for lower duration, lift, and early intake close times.
Lopey or hitting cam for a m8 107? I dont run hard above 4500 rpm. Thanks kevin, great video sir 👌
I ran a andrews 26h in my 16 streetbob and loved it
Thank you Jimbo. There are many options out there. Sometimes a hard lope setup doesnt provide the best low end torque. What bike are you riding?
17roadglide special m8 107
Where do you live? Passenger? Combined weight? Pipes? etc...all that matters.
I get that brother, i did the 26s in the bob, running a decatted stock header with mutazu 4in megaphones and a dynojet powervision currently.
Great video and excellent explanation!! I’ve mostly dealt with car cams for 30+ years and still learning things!!! Curious on your opinion, I have a 08 FatBoy 13k miles, Arlen Ness Big Sucker, Bad Dad 2 into 1 exhaust, currently has a DJ PC-V (will be looking to change to a PowerVision) and upgrading the compensator to the DarkHorse Comp. I mostly ride solo (200 lb), we have hills but mostly flatter kind of riding in the southern North East. Also normally ride in the 2500-5000 rpm range with an occasional “let her eat” kind of riding. I have been looking at the Andrews 48H but wasn’t sure. Any sort of guidance would be great, and once I figure this out I’ll be in touch to order some parts, but will have to order parts as money is available for it. (Daughter in college) thanks again. I almost forgot I do have a batwing fairing and hard-bags on the bike.
That is a fantastic cam if your goal is the lowest torque you can get. If you havent, take a look at my latest video on M8 cams. I compare cams to help folks better understand the numbers. When you look at the specs of that cam, you'll understand why it makes torque so low. Look forward to hearing from you when youre ready.
I'm still trying to figure out what cam I want. So many choices
I installed the S&S 510c cam in my 2002 Dyna, along with the S&S 97ci kit and had my heads ported, polished and decked and it’s a fun bike to ride. I’m thinking of using the S&S 509c cam in a stock 2005 Heritage softail. How will this cam compare? I has a softail with an Andrews 44 cam in the past but it felt more like a higher revving cam.
Depends largely on how the cam responds to the heads. Its a system. But...if you take the specs and compare them, along with the overview I gave, you will understand how the change in specs will affect what you have now, in general.
I'm only starting understand the cam language.
Excellent video Kevin! Question, how much does having the heads flowed effect cam choice? I think they go hand in hand as in you should do one with the other. I have a 2019 Limited, a 1000llb bike and think I should concentrate on the lower rpm range. Whats the best cam choice for my bike if i have the heads flowed? Thanks man! You do an awesome job, keem'em coming!
Tremendously. Heads and cam need to work together and should be chosen together. There is no best...and there are many ways heads can be done. Whoever you choose to do your heads, us or others, should be the one to recommend the cam. Low to mid range torque for touring. Thanks!
I've got a 2020 Breakout 114 with a Wood 22x cam. Torque isn't the word. It raises and evens out the idle somewhat and is a torque monster. It's just fine to cruise on the highway or putt around town and has instant power when you need it.
Hey, I just caught your video explaining cams. I have a stock 2003 TC88 FLHRCI 31k. Chain tensioner pads caught just in time. Not doing the up grade just yet. Want to go with Zipper's in the future but for now replacing tensioners, S&S quickies, HLJ 2313SE lifters, DS "Daytona" performance oil pump, new analog oil PSI gauge. and trying to decide Cams or no cams. I know there are limitations for my stock bike and found the "night train" site with a dizzing awray of cams to review. it has highly suggested to run no more than .250 duration and .510 lift cam in my stock set up. trying to narrow down and am in the range of Andrews TW37, or 37B, I ride the mountains of NC. Not going to the strip any time soon wanted to know if that cam would be a good bolt in fit for my bike with just a bit more pep. Thanks for any in put.
Stock 2015 FLHXS 103 with SE super tuner Pro , SE heavy breather and 4" Rineharts with decatted head pipe....your thoughts on the T Man 555 torqster cam I ride mostly solo and like the feel of mid range power not so much off the clutch .
Hey Kevin, great video as always. I have a 2020 Street Glide Special 114ci. with S&S Power Tune Dual Header, SVT boneshakers slip-ons, Arlen Ness Big mouth Air Cleaner, S&S 475c Cam, oil pump, plate, inner bearing, pushrods, lifters, and Thundermax tuner.
This week I upgraded my primary with a Darkhorse compensator sprocket, Trask clutch basket, Hayden M6 tensioner, and Rekluse TorqueDrive clutch.
Everything is running great, however I can't go to neutral. She is up and down shifting fine to every except for neutral. The Rekluse tech said to run she for 500 miles to break-in the new clutch, and it should fine neutral when it break-in.
1. What is your advice on this?
2. Will the Darkhorse compensator sprocket tear up my stock crankshaft, since it doesn't have a spring?
Thanks!!

You have a very good list of parts there. Im assuming you have a hydro clutch...which doesnt allow adjustment. That is one reason i run the clutches i do...and i'll explain. First take a look at this video th-cam.com/video/EHSiTmTVnu8/w-d-xo.html In short, it comes down to maximum pressure plate travel, and stack height of the clutch. You must have .060 pressure plate travel on a cruise drive to fully release the clutch. Stock...it's right at that already. If the stack height of the clutch pack is even slightly too thick, that travel, or clearance, is reduced, which will cause your clutch plates to drag making it hard to find N. This is why im not a fan of clutch packs that add plates. One other thing to look at...if you are running fat grips, or and adjustable lever, or covers over your lever, this will reduce clutch travel as well. Hope this helps.
@@KevinBaxter Alright, thanks!!! I'll look into it.
@@KevinBaxter Alright brother!!!! So I have Arlen Ness grips and Arlen Ness levers, and I looked at my clutch lever and grip, and it turned out that lever at the side closed to the controls was hitting the grip 3/16 of an inch too early. So I took my grinder to it, and shaved off enough to get the entire clutch lever travel. THANKS A LOT!!!!! PROBLEM FIXED, Now I find neutral with ease. THANKS!!!!
excellent...sometimes the biggest problems have the easiest solutions. glad i could help.
Glad I found your channel tons of great info. I have a 09 night train what cam would you recommend for street / touring I'm in new Mexico we have mountains all over my bike has stock throttle body a Arlen Ness velocity intake, V&H pipes, stock heads, cobra auto tune. Down the road I may put a 110 kit in so possiblity a cam that could work well with both. Not looking to race just a improvement over stock for some good street torque. In the past I installed Andrews 54H cames in my Electra glide pretty much same set up and they were fantastic in that heavy touring bike and how I rode not are if they would also be a good choice for a Softail. I was interested in the easy start cams from s&s as they sell complete install kits with plates and pump as well. Any infor would be great since like you said there are so many options it can get confusing. Thanks
I’m waiting on my S&S 509c cam chest kit to be delivered now. After my new cams are installed what do I have to do in the way of tuning the bike before it can be ridden regularly? I already have the stage 1 intake and the EFI upload that Harley recommended. Time, money and location will be a factor in getting a full professional tune.
What do you recommend for a 2018 road glide only modification done was a Trask nasty bastard 2-1 exhaust
Would you say :
465 s&s
Fueling or
Something els ?
Thank you
You're welcome
I have a stock 99 road king 88 ci. Carbie. I’ve chose a S&S 509 only goi to have slip ons and maybe air filter .. was this a good choice for around town and some highway riding. I just thought a s&s 510 was to hot for me. Thanks. From Australia
I'm sorry but that is all very confusing. I was thinking about putting a cam in my 97 dyna. but think I will keep it as it is, after watching this.
guy is super intellegent ,i dont understand what ya said,imma just drop my evo off and say do what you do best and call me when ya done lol
I presently run a 475 cam but want to tame the engine down is the 465 a better choice thanks
Woods or Red Shift
New Subscriber here. Your videos have so much information, I had to get in on it. I've read that the TTS 100 cam can give some instant grunt in a M8. Have you had any experience with that cam?
No I have not. Not familiar with it.
I went with the screaming eagle 462 power cam, on my 2o21 new road glide limited and its putting out great Torque at 116.5 at 3500 rpms and getting 102.5 power, se tuner, and vance n hines power duals, with rinehart slip ons that was free, my goal was to bring up the horsepower on a stage 2 build, as a bonus I'm getting great early on torque, seen many posting to get the torque cam, so I went with power cam, and completely no regrets, and the sound is amazing too
Thanks!
Youre welcome sir. Thank you.
Hey Kevin I have a 2013 Road King with 103 motor and I’m thinking of replacing my oil pump and cam. Do I need lifters as well and new push rods???
Still confused 🤔😆 . Built an engine for my 2010 RK ,my first one. Standard 103 with auto decompression releases.
103 heads plunge cut and port matched
S&S 650” springs
58mm CVO throttle body
5.3 g/s screaming eagle injectors
103 factory barrels bored to 107
Wiseco Trekker pistons and rings 10.5-1 compression
Andrews 54H cams
S&S crank and flywheels
Fueling cam plate and HV oil pump
Fueling HV lifters
Fueling hydraulic tensioners
S&S adjustable pushrods
Vance & Hines true duels exhaust .
Got good torque from 1800rpm up to 113ftlb at about 3500. Horsepower around 103. Can I get better torque by changing my cam? Recommendation on better torque cam for my build ? Most of my riding is corners , hills or 2up. Thanks
I actually have v&h power duels with screaming eagle slip on’s , sorry . Was recommended tw555 woods cams . My aim is low end torque and reliability. The wife and I often take off on long weekend trips and have a 15 day trip coming up in a few months down to Tasmania from QLD . A few thousand ks.
Kevin, I had a Zippers 468 RS cam installed on my 107 Heritage. It’s tuned with a Powervision Tuner from a very reputable guy tuning at the HD dealership. Stock I was getting around 42mpg and now I’m barely getting 32mpg. Is this normal for a Zippers cam?
Kevin, is there a typo in your pictogram at 5:06? Your intake never opens!!!
