I would like to what else is out there for the after market. I love the bikes but do not like to do business with the dealer and do all the work my self 🤔 love the channel great content 😁
On my 09 FXSTC I did a 103 big bore with new ACR heads and .030 head gasket SE 204 cams with 1.7 rockers. SE cam door and oil pump Changed the final gearing to a 30 tooth front and a 70 rear. Thing runs effin awesome very happy
I have the tire shredder kit and went with the 585 cams…and to be 100% honest…even the guys at the dealership can’t believe how nasty that thing is. Once and a while you just get that perfect combo that makes a monster. Even my wife’s M8 114 stage IV can’t touch it!
I have a 2016 SGS that I bought new, had the Tire shredder kit installed with T-580s and a Screamin Eagle Cam Plate, I raced a guy on a 2021 SGS Arctic Blast M8 with a stage lV, Granted he has around 30 pounds on me, He even went back to HD shop asked them what the hell, they told him that my 2016 is crazy how it runs. I love my bike
Cams are the trick in this kit. Are the 585 the same cam as T-580s ? My kit is due to come in 8/19 after waiting 14 months. My gut says I need to change out cams in the kit. You guys use ThunderMax tuner?
I'm installing the tire shredder kit on my 2015 FLTRXS and having the 585 cams installed instead of the 259 cams. I have the rinehart racing headers, CFR exhaust and have a powervision tune. What were your HP/TQ numbers? I should have my bike back within the week or so.
Man I just bought a 2014 street bob and had no prior experience with Harley motors or Harley bikes.. been watching all you’re videos religiously before I bought the bike and still Watching now and I’ve learn so damn much from you gixxerfoo!!!! Just wanted to say thank you for these videos for us foos that don’t jack shit lol already did my first oil change on the bike and ready to swop out the tranny fluid and primary fluid! Again thank you! Got me wanting to do all my own work on the bike so save on the labor cost.. lol
Hey, may I ask if he made the suggestion on a different video about this exact bike or is it off this video ? I’m on the lookout to buy one and would appreciate it if you can share the suggestion. Thanks
The 103/96 is a rock solid engine despite what you read on the internet 😂 there’s a lot of guys that own shops that want you to think their garbage to sell you parts. Sure the early 88s have some issues but the twin cam 103/96 is pretty bulletproof
They really are solid engines, you hear of a 1,000 failures in a sea of millions of engines that have run for years without issue and the focus is on the failure.
@@GixxerFoo that Baxter guy is the worst, or Tman, they have some good info, but if you listen to them for 10 minutes you’d think every single Harley on the road was an oil leaking crank out of spec piece of crap and they’re really not 😂 the other problem is people run to the forums and make a “has anyone had this issue” post every time a part fails on a bike…Harley’s are very reliable quality motorcycles that are mass produced, anything that’s mass produced has a lemon here and there and has parts failure here and there, it’s nothing new.
I have a 2009 FatBob with 103 Stage 4 Race kit, 259e cams and just SE slip-on mufflers. Dyno at about 112/111. Very reliable, pulls like a beast and so happy.
That's awesome! Those factory headers are pretty dang good, they really don't get the credit they deserve. Some good slip-on exhaust work really well, those are very impressive numbers!
I love this my favorite channel on the entire Internet every time something new comes out. I’m here man. I love this channel. I think you’re a great host. Keep up the great work sincerely Spider HAMC NOMADS DIXIE Chapter////I I have a 110 CVO ULTRA with the stage 3 kit”
4 years ago i purchased a 2014 Road King FLHR 103 HO absolutely love this bike. Since switching over to full synthetic in all 3 holes I’m achieving 46 mph religiously. I used to get 41-42 with detergent oil. I had a 2005 Road King Classic before this one. The rider and performance changes they did to the Rushmore series bikes are outstanding. 2013-2016 bikes were Rushmore. 2017 switched to the M-8.
It's a mean kit, guy that works at my local dealer has one on his Road King. You pulled some damn good numbers with yours, what exhaust are you running?
I got the factory 103 HO on my soft tail, it backfired allot until got the Screaming eagle ignition module and I went to the Cobra Neighbor haters slip ons..Bike sounds amazeballs but I still get some back fires now and again..Its a Gold Hard candy Custom..Love this bike!
I got a 2016 heritage softail with 103HO. It’s got more than enough power for me. I don’t ride a harley to be fast anyway. I just never had a desire to mod engine and compromise the reliability to be faster. That 103HO will do anything I ask it to do whether it’s climbing a mountain or crossing the country. Harley got it right with the 103HO and I’m gonna leave it alone.
It’s all in the heads ! My 2015 RK I used my stock pistons and sent the heads to zippers performance for there mildest CNC port they offer called 1.8 for the slightly larger intake valves 700$. Put it back together with.030 head gasket and heads decked made it 10.25 comp. I already had Andrews 57h cams & powervision with cobra power port headers & SE street cannons. So this is the cheapest big gain set up you can get. & never even had to remove my cylinders. Had it dynoed with the powervision & ended up with 108 hp & 116 TQ & a very happy customer 👍 I did it with 14000 miles on it. Forgot to add I did it all myself including the cams a year earlier so no labor costs
Doing it yourself is the way to go! That's really impressive numbers, the twin cam engines really respond well to compression. You made some big power on the cheap, Zippers does really good work too. What was the turn around time sending your heads out?
www.bigboyzheadporting.com/TwinCamComp.htm Wanted to add this link that helped me figure everything out as for what I wanted to accomplish. That plus a lot of other research on various Harley forums
Very true harleys absolutely make there power in the heads, but those heads need the right supporting parts to be able to make that power. They cant do it alone
If you take it to over 120 + rwhp and torque ..get rid of the compensating sprocket and clutch and replace the compensating sprocket with a solid plain replacement sprocket and a Baker King Kong Clutch or it will all self destruct ..been there and done that twice ...the last time it twisted up the fly wheels .. Was not a pretty site . used the latest screamin' eagle compensating sprocket and screamin' eagle clutch plates that shattered in to gravel of pieces parts and parts pieces
Hello, Had the Woods TW222 cams installed in my 2013 dyna street bob. They made a huge difference. Needed to run the autotune in my fuelpac. Very happy. Thank you for your advice.....Gary
That Wood is just so hard to beat for me, I bet it feels like a new bike now! I am really happy to hear you're enjoying it! Let me know how it runs after you get your auto tune done and get it dialed in some more!
@@GixxerFoo I agree. Mine's a '99 and carburated; Timken is in there. It could stand some more power though. Right now it has a k&n air filter, re-jetted stock CV carb and true duals with some CVO 110 slip-ons. Runs solid with over 50K miles. Subbed..
Old video but...picking the wife up a Softail Tuesday with a 103. 6600 miles on it. How much do I need to worry about the cam chain tensioners? I feel like with the 96 people don't worry about it but with the 103 they do? Did Harley go backwards with this?
Have a 103 Heritage dyna tuned. Appreciate the information of the other options available and estimated cost. My 3rd video watching, 3 is a charm: subscribed. :)
Many thanks! The 103 had all the improvements from over the years, the numbers on paper don't look much different than the 96. But if you ride one you'll feel the difference immediately.
I bought the 2015 Road Glide Special out here in Cali and with the smog is was a DOG! Ran hotter than hell, didn't get 200 miles on a tank and had no throttle in 5th & 6th gears. Purchased the Screaming Eagle race tuner. Installed a Roland Sands intake and Reinhart slip ons'. Took the stock exhaust off, emptied out the catalytic converter chamber and reinstalled it. Had to take it to Arizona to have it dyno tuned. Like a brand new bike. 92 hp with 113 torque. Runs way cooler, 240 degrees when it's 100 degrees outside. I get 230 to 240 miles on a six gallon tank. And of course, it's not the fastest bike but nobody leaves me in the dust. This thing is a rocket ship recliner. These days Harley is begging me to trade this in on the M8. Thing is how do I take the Cali smog off this thing and pump it up like every other Harley I've owned? The stage kits are crap and full of problems. These things eat, breath and fart. You improve this on the Harley it's like you have a brand new bike.
Thanks GixxerFoo straight up advice I just got a 2015 RG with only 6000 miles on it and I'm looking at giving it some more power trouble being down here in NZ parts are way more expensive. Thanks again from NZ
I appreciate you watching and your support! I bet you got some beautiful riding country around there, does it already have the stage 1 done or is it still stock?
@@GixxerFoo Thanks Brother yes we do have some great ride's down here but usually if you ride far enough there's always somewhere great to ride. My RG has Monster Round slip-ons I'm not sure apart from that it was imported from the States. All the best brother
The 103 is a very nice motor, it performs very well in the Street Bob. I was impressed with the one I rode that had a 103, it was cammed and it pulled hard out of the hole.
Thank you for clearing that up, the most explanatory video on the 103's highly appreciated, On my 2015 Road glide 103 I went to the tire shredder kit the 110 it's like holding onto a bull so impressive so exciting to ride, I don't know I could be wrong but I feel like my bike has more balls than the 114 117 and even some 128 LOL am I wrong, my torque is 123 at the rear utilizing screaming eagle super pro tuner, using Vance & Hines headers and cross pipe.. on the clutch running the scorpion clutch
You are welcome! I wouldn't doubt it pulls harder than bigger inch motors, you've got a the right tuner and a good exhaust setup! That makes a huge difference, the salesman at my local dealer had the tire shredder on his Road King and it hauled ass! He was in his 70's and a real hardcore rider, he went out with a heart attack riding home one day.
@@GixxerFoo wow what a way to go well God bless his family and Godspeed to him!! Really appreciate all your videos. Great information second-to-none thanks!!
I ordered from Harley-Davidson in 2013 the new cases the screaming eagle 4.070 Pistons jugs the CNC heads and the 4 3/8 crankshaft. I added fueling cam plate oil pump and lifters I added Andrews 67g cams I have the crank trued and welded I had the jugs done and my bike makes 126 horsepower at the back wheel and 118 ft lb of torque I changed the primary to the screaming eagle 315 and she'll do 145 comfortably with the original five speed this is the engine I put in my 01 road glide to replace the 88
That's a very nice engine you built! Andrews makes some awesome cams for Harleys, great company and they also grind cams for many others as well. You've got some serious power on that bike, I bet it's a blast to ride!
@@GixxerFoo one of the stupidest engines I've ever built the bike doesn't weigh anything does 10 second quarters I only weigh 160 lb myself total idiocy thanks for noticing.
Still got the 103 stage 4 on the cabinet,,, tuner is vance and hines,, configuration online,,, i ve got the tts but there no dyno program to do the tuner,, but still pulling hard
The only way to know exactly what cam set is in there is to pull the cams out, but if you just want to know if it's stock or not there is a way. You would need a tuner that allows you to view the intake valve open/close value. The open and closing values for the stock 103HO cams are 02 BTDC and 30 ABDC (before top dead center and after bottom dead center) this tells the ECM when to read the MAP sensor. If those values differ than the cams are likely not stock, that's the best way I know give you an idea if they are stock or not without pulling the cams.
@@GixxerFoo you are the official H-D savant!! I appreciate the feedback and the informative videos when making hard cash errand decisions when upgrading my H-D.
I'm confused. Did you buy this used or brand new ? Did they use 2 different cams for that year and model because I have the same bike (bought it brand new)
@@gaknskk I bought mine new as well, the only power upgrade I’ve done so far was have the Sceaming Eagle ventilator elite installed. To compliment my Rhinehart slip on’s.
103 is solid and can make decent power while maintaining longevity I put a 103 kit on my 07 wide glide 54k miles only thing that shit the bed was my fuel pump at 50k not a big deal to replace though
When I bought my 2013 Road King off the showroom floor it had a stage 3 kit and an aftermarket exhaust from the dealership in Victoria, BC. It would snap my head back when I twisted the throttle on the freeway. Does the stage 3 kit mean it has 110" cylinders? I need to buy rings for the rebuild, what size rings would they be? Thanks for the vid!
On the 103 there were so many different variations of the stage 3 kit at that time it would be hard to tell without tearing the bike down measuring the bore. Since it was done by a dealer you can have your Vin number run at a dealer and they will be able to tell you everything done at a dealer on that bike. At that time there were stage 3 110 jug kits but also high compression stage 3 kits with cams too.
@@GixxerFoo thanks, the dealership is out of business. I had a wreck several years ago and it's slow going getting all the parts together that were messed up, I'm still saving up and looking for a frame. I have the engine torn down, ready to put it in S&S cases. What would the bore be for the 103 and 110 respectively? The dealership is elusive about the answers (I think they want me to just buy a bike from them, but I have an '83 sportster that will do for now.)
i enjoy my Twincam 96 the way it is , yes it's a noisy engine but all Harley engines got some noise . You just need to change the oil every 2000 miles and use a good quality oil and filter. Don't be afraid to use a 60 weight full Synthetic oil for extreme hot temperatures.
Great information! I have a 2012 Roadglide with the 103. The kits, like you said unless you go all the way are less than impressive. Currently i have stage 1 with 2 into 1 exhaust and SE street tuner. I’m looking to upgrade with a Thundermax ECM, and a woods Tw-222 cams. This should net me about 97-100 hp right?
@@GixxerFoo i have a slim with the h o 103, stock, and a flht 88, with 95 kit, and a bolt in cam. So thank you for all the twin cam videos. Very helpful
I bought a used 14 SGS 103 and i have Boneshakers/ V&H true dual headers/ SE intake had it dyno and i got 104ft & 84HP. but i’m looking at getting the tire shredder kit installed at dealer over the winter but all in out the door is about 4gs $$$ pretty penny. What’s y’all take on it. Thanks ride safe
I also have a 14 SGS 103 with Stage 1 upgrades. Just paid her off, and have ridden her for 55K miles so far. I am thinking of doing the same kit you are.
What about performance upgrades for cvo 103 like thiner head gasket for higher compression and Cam upgrade .what cams would you recommend not looking to go with se more aftermarket looking for performance and a little chop. Thx. Love your videos
I just bought a 2013 softail slim with a 103.. it has 85k miles on it.. I figured Id do a 110 kit, cams, and cnc'ed heads. I figired a cam plate, true and weld flywheels and timken conversion also. But Im wondering, will it be ok to do this without actually rebuilding the crank ?
If you plan to go that far with the bike and the mileage that it has on the current lower end I would go ahead and do the crank. That's a lot of miles down on the bottom end, planning on a cam plate you'd likely find the run out on the crank is too high. You'll need run out ideally at .003 or less with a billet race cam plate.
In the market for a Harley right now. The 103 is plentiful and at a good price point for me. Specifically in the 14 streetglides and up. However, the M8 bikes are there too.What’s your opinion, I’m currently set on a low mileage 2021 street glide and ultra glide. But I can save a few grand getting a 2015 103 with about 20k on it.
Love your channel and your videos. Looking to upgrade to an Ultra Limited. I’ve noticed that the ‘14 models are quite a bit cheaper than the rest of the Rushmore bikes. Is there a reason and what should I look for?
I know this post is old but here is my question. 2013 Tri Glide. Will be installing woods 222 cam. S&S High volume oil pump and cam plate with S&S lifters with adjustable pushrods. DK customs 606 high flow breather with factory cat deleted headers and gutted VH pipes. What numbers should I expect to see out of this setup? Power vision tuner. Is there a better woods cam for this setup? Trying to stay with drop in cam setup while gaining torque along with some top end speed. Tavel in the mountains and out west pulling a trailer at times. Will be making the Sturgis run next year pulling trailer. Trying to also keep a reasonable fuel milage.
Wood 222 is going to be the best all around bolt in for your setup, that cam really excels in heavy bikes with the torque curve and top end power. With a catless factory head pipe and V&H mufflers and a power vision canned tune for the setup you should land around 90 to 95 horsepower and north of 100 foot pounds of torque.
I have a Two 103 touring bikes..2015 RK, 2016 SG Special....love them. I also have a 2019 RK Special and a 2019 Fat boy with 114 M8s. Yes the M8 have more power but I still love my Twin Cams. Let's face it HD has to make engine mods. Other than paint how can a HD be improved. One of my Twin Cams has 78k miles and she runs like a dream. The M8 blow oil smoke sometimes and you definitely smell oil burning on start up. Most of my family think the engine sucks. Only because HD has not come clean about this engine. First the oil migration to the primary and now HD is on their third oil pump improvement....not to exclude the new M8 oil filter they rolled out....why? My two M8 only have 6300k miles between them so time will tell. They both are getting the new SS came plate and oil pump in Oct 2020 when I have time to replace them.
Have you had your M8's in for all the updates? I saw they started drilling the case on the primary side and putting a vent/return tube in there. Seems like something they would of caught in development. I've talked to several people that came from a TC to an M8 and they said the same thing.
I have a 2014 Electra glide ultra classic with Reinhart exhaust and a screaming eagle high flow air intake, it has the oil cooler and it putting out 91 hp with 111 lb ft of torque is there a way to tell if this is stock with tune only or if the put a cam in it?
The 103 during the 88inch era was only in the Screamin Eagle CVO bikes. The replacement motor for the CVO was the TC 110 when the 103 made it into standard production of all models. But at that time the 103 you're talking about isn't exactly the same as 2009 103. This 2004 103 shares much more with the 88 in that time period.
I’m considering getting a new 1200ns, FXDL with a 103, and a softail S with a 103. What would be your pick? I’m leaning towards the Dyna but the 1200 is new. However for long Texas straightaways the extra power might help.
They are really great bikes in their own respects, I might be a little biased cause I really like the Dyna Low Rider. A Softail Slim is great riding bike but it does sit very low to the ground and doesn't have much cornering clearance. The 1200 is a fun bike, I have a 2016 1200 custom and my wife rides a 2017 Sportster 48. But if you're running down long highways it's gonna get real small after a while, I'd say the Dyna would would be my pick. The Low Rider is like a big Sportster, it has room to stretch out and it's a lighter big twin but it will still ride good down the highway.
I have a 2012 electra glide. All i did was put in a decatted stock header pipe, cobra 909 uppercut slip on mufflers, big sucker air cleaner, dyno tune and andrews 57h cam. Makes 97hp 107tq. Sold
Those factory headers really don't get the credit they deserve, they are really pretty damn good. Once you get that cat out and add a good slip on like you did.
Those are fun bikes to ride! Ducati just has that Italian refinement, they are unique in the feel and ride like the Harley. You ride any Japenese bike and they all feel about the same.
Good information well presented. I’m currently looking to get my first ever Harley and I’m looking at a 2015 ultra limited with the 103 engine only concern the one I seen at a good price had 30,000miles on it, what would your views be on that mileage ? Or should I go newer and get the 107 or 114 m8 Thanks in advance any help would be appreciated
I like the late model twin cams since that's where they got it right in my opinion. Now the early M8's up to 2020 have some issues with oil sumping and piston oil jet coolers coming loose. With that twin cam at 30K I would just have the tensioners checked and make sure they are still in good shape. With they hydraulics they can last up to 50K miles, but better safe than sorry.
@@GixxerFoo thanks for the reply and info much appreciated. Are these 103 Rushmore’s engines good for high miles then? I’m not a fan of the sound on the new m8s plus the stories put me off Aswell on then 107,114’s. It’s more for just long rides and slow riding not for speed at all
@@boylejohnstone1 on a different note my 103 lost a can tensioner and wiped out the motor with 26,000 miles. My 2017 m8 now has 76,400 miles on it with only oil changes and a stator. My 82 shovel swallowed a valve at 29,000 miles......my 98EVO is still running along with 102,000. I work on 5 M8s that i have vented heads to atmosphere like i have done with every Harley from 76 till 2020. M8s we do run 4 dots low on oil stick. And vent crankcase to atmosphere ( 8 bucks to do not 100+) So i think the m8:engineers also run too much oil. Maybe why you dont see many softtails stumpping...🤣🤣🏝
If you are looking to re-build an engine with the goal of power, it'd be better to score a 110 engine and use the 117 'drop-in' cylinders as the heads are a much better casting. Get the heads fitted with bigger valves and port them and your numbers can be over 140 in torque and horsepower. If it is a rubber mount bike though you will have to upgrade the engine mounts in order to stop the dreaded 'death-wobble'.
I've heard of the death wobble and know some guys who had monster S&S Dyna Engine builds that experienced it. There are after market stabilizer links for the engine mounts out there and they do wonders!
@@GixxerFoo Yes, but stabilisers are not enough when you get up to high power levels - you need different mounts. I use ones from Big Bear Performance as they offer a little sideways adjustment on the front mount that enables you to get the wheels aligned properly. My Sporty's mounts were old and buggered so I fitted ones from Drag Spec as they are firmer and the handling on my Sporty is great now. If you were to see my bikes you would be in awe as so much is changed or altered..... my brother in law says it's easier to remember what parts I haven't changed, modified or re-engineered. I have had the bikes 11 years now and it is a constantly evolving situation. My Dyna has had over 3250 spent on it including original purchase price (new) and the Sporty about £10k but that one was second hand.....
I just bought a 2010 Ultra Classic 103 and it's leaking a few drops of oil every day. Oil and trans fluid are fine. It looks like it's coming from where the pan bolts onto the bottom of the motor. This is my first Harley. Any ideas where it's coming from? Do they have a reputation for leaks?
i have a question, i have reaper 574 cams, big bore to 107 10.75/1, 55 hpi tb, ported heads, tmann no loss air filter and two bros 2 into 1 exhaust. it dynode at 106/112. what cam would make this setup better?
You've got a nice setup with some good horsepower and torque, that's about right inline with that cams performance. I would check out Wood Cams, I am not sure what year your bike is or what it is (dyna, softail, tourer). Assuming you have some upgraded valve springs with the head work you can actually go with 555 or 222 from Wood. They work with stock springs but they love some compression. TW-7H is another monster for your bike, depending on where you want the power to come on anything from Wood will crush your current numbers.
I’ve been riding a TC 88 for 19 years. Seems like back in the day when I bought the bike Harley-Davidson offered a kit that could take the TC 88 to 113. Any idea how that measures up?
Brad I bought a new ‘02 ElectraGlide and at that time they only offered a 95 kit, which I had the dealer put on .. the SE models in ‘04 had 103s but I don’t believe that was offered until a few years later
I think that depends on what the motor condition looks like. Ask the seller questions. Test it. If you think its not worth the price, still get it, but only if you are able to get it for what its worth.
Hi, a little off-topic question (but maybe not so much). Based on your I see deep knowledge what do you think about the flywheels scissoring; on the late TC103s it's still an issue to be concerned of? Especially if hopped-up or brought to 110 I tend not to do clutch drops or lug the engine, on the contrary, I like to wind it up when the road is right
It hasn't seemed to be wide spread from what l've seen. When it does happen it's usually someone waaaaay overbuilding an engine and riding it extremely hard. There are a lot of Twin Cams out there with with well over 100 horsepower reliably.
I was worried two months ago when I bought my RK from Harley having 70k on it! But they promised me that this 103 was solid! But the valet train can be noisy
When bigger cylinders and higher compression pistons are added to the 103, would these things effect the dependability of the bottom end. Crank, bearings etc.? Thanks, I enjoy learning any new information you may impart upon me.
It's always a possibility but a lot of that depends on how hard you are on the motor. If you just ride it and not beat on it constantly, take good care of it, it can be quite reliable.
Excellent information! In my opinion, best knowledge about Harley-Davidson engines in the last three decades. A quick question. I am considering buying a Tri Glide. Choice between a 2017 or newer M8 or going back a few years earlier to a 103. It looks like upgrading a 103 to get some more torque is a great option. Problem is I could get a 2017 used for only $1,000 more. I'm not a speed freak, I'm just concerned about the big three wheeler moving when I need it to. What would you do and why? Thanks for any reply
Thank you! The trikes really needed the extra power of the 107 and 114 M8's, but the 103 does very well and a cam swap will really get the horsepower and torque where it needs to be to really pull a trike. Now the 2017 M8 had oil sumping and oil pump issues, I would take the VIN to a dealer and see if it had any warranty work done. 2017 engines with the original oil pump design had the issues and Harley replaced those with a newer designed unit under warranty. If you are able to verify that I would go with the M8. But the twin cam 103 is tried and true, they got the issues with the twin cam worked out on the 103 and of course they changed over to M8 shortly after. My opinion is the 103 is less likely to have an issue vs. the 2017 M8 which was the first year of that motor, I've had some bad experience with the first years but that's just me.
I have an original 88 2005 RK that was build by the previous owner to a 103 Screaming Eagle(old). He put a Screaming Eagle 6 speed transmission. Cams seem original like on the 88s. He did put a SE intake.I have replaced the cam plate with a Feuling cam plate with hidraulic tensioners and new larger fuel pump. So the engine is far from original. Question is: When I will need to rebuild the top end, with what can I replace it with? I don't want to go back to 88 and I don't want to bore out the cylinders . Can I use something bolt on? Cheers! P.S. I am not a mechanic and english is not my first language :)
I have the 110 kit (still in boxes) you said to stay away from. Can I change any of the components (heads, cams, pistons) to make it work better? Purchased it from a guy that sold his bike before he had it installed. Paid $800 for it and not sure if I should cut my loses or try upgrading the kit.
If I go for the 110 package can the stock crankshaft handle the power? Seams to me I might as well go for the 120 st crate motor??? Love your videos keep them coming!!!
If you keep it mild and don't beat on it the stock crank will be alright, they are pressed cranks so biggest thing is just not lugging the motor. I would get at 120R before the ST, the ST is the same engine as the R but the ST has a milder cam.
A little off topic, but what is your opinion on the stock CVO 110 Twin Cam, not an aftermarket 110 kit? I have been reading horror stories on some online forums about the lifters going out. The one I just bought has 41,000 miles, kind of a lot for a bike and I am hoping that any issues the 110 has have already happened and been corrected. What are your thoughts? Thanks for the great videos.
I heard of that happening but it was kinda like the cam chain tensioner in the 88. It didn't happen to every bike out there and depends who you talk to it was maintenance related. Personally l wouldn't be too worried about myself.
I should have read a LOT more about the 88 because I found a decent LR with the 88 with everything I wanted on it---low mileage, rack/bags/shield/engine guard/back rest/ and good paint and not bad for rust. It has been one problem after another. Over and over , thousands spent just to get it running AND haven't even't replaced the chain tensioners yet. Such a disappointment. SO, spend some extra money and buy a late model 96 or the 103. Even a nice 88 with low mileage COULD be a real POS.
Then 88's were really hit and miss, some were flawless and others had all the known issues. The later year 88's weren't too bad but the 96 had the issues corrected by then.
@GixxerFoo I picked it up with 40k put exhaust on it and updated the timing guides and oil pump along with s&s adjusted push rods. Not sure if someone else did heads or something before I got my hands on it! But trust me I was very surprised to edge him out. He's fatboy is stock though so I sure that's holding it back Maybe?

That Stage 3 setup makes really good power over stock. The stage 4 is a high rpm kit, the stage 3 keeps the power in the middle. Depends what rpm range you're looking to ride in mostly.
If any one is actually serious and can't wait ..I have a complete 110 top end I' all take half price for ..itvhas exactly 30 miles on itvi put on myself ..and pulled the while top endvoff cams and throttle body pistons cylinders and heads injectors the works all you will ever need to uP grade a 103 to the 2017 Dyna S 110 cubic inchthat make 90 HP to the tire and a 100 gt lbs torque
I have a 2010 FLHP with the 103 motor. Had it 18 months now after riding Evos since 1999. I like the ABS, cruise control and the police siren that still has the working "air" horn, but damn do I miss my Evo bikes. So easy to work on and diagnose issues and they have THE best sound. My 2010 has been a pita with it's sensor issues. Been dicking with it for a couple weeks till I gave up. It's at an indy shop now to try to figure out some sensor based issues @ $140 an hour. Woohoo! No AZ bike week for me. Anyone want to trade me for a Road King Evo? :)

Would you choose a high compression kit or go with the 110 big bore kit?
I would like to what else is out there for the after market. I love the bikes but do not like to do business with the dealer and do all the work my self 🤔 love the channel great content 😁
There's a lot of quality after market kits out there for the twin cam.
Thay really seems like the best way to go!

Now we're talking!!
I just 103 2012 9000 miles I love it
Thank you for information very helpful bless you bother👍🏽
On my 09 FXSTC I did a 103 big bore with new ACR heads and .030 head gasket SE 204 cams with 1.7 rockers. SE cam door and oil pump Changed the final gearing to a 30 tooth front and a 70 rear. Thing runs effin awesome very happy
That sounds like an absolute screamer, I bet you surprise some guys with their new M8's!
I have the tire shredder kit and went with the 585 cams…and to be 100% honest…even the guys at the dealership can’t believe how nasty that thing is. Once and a while you just get that perfect combo that makes a monster. Even my wife’s M8 114 stage IV can’t touch it!
I have a 2016 SGS that I bought new, had the Tire shredder kit installed with T-580s and a Screamin Eagle Cam Plate, I raced a guy on a 2021 SGS Arctic Blast M8 with a stage lV, Granted he has around 30 pounds on me, He even went back to HD shop asked them what the hell, they told him that my 2016 is crazy how it runs. I love my bike
Cams are the trick in this kit. Are the 585 the same cam as T-580s ?
My kit is due to come in 8/19 after waiting 14 months. My gut says I need to change out cams in the kit. You guys use ThunderMax tuner?
It’s a big bump stick man
I'm installing the tire shredder kit on my 2015 FLTRXS and having the 585 cams installed instead of the 259 cams.
I have the rinehart racing headers, CFR exhaust and have a powervision tune. What were your HP/TQ numbers? I should have my bike back within the week or so.
Man I just bought a 2014 street bob and had no prior experience with Harley motors or Harley bikes.. been watching all you’re videos religiously before I bought the bike and still Watching now and I’ve learn so damn much from you gixxerfoo!!!! Just wanted to say thank you for these videos for us foos that don’t jack shit lol already did my first oil change on the bike and ready to swop out the tranny fluid and primary fluid! Again thank you! Got me wanting to do all my own work on the bike so save on the labor cost.. lol
Hey,
I bought a 2014 Super Glide today, based upon your suggestion. I love it. Thanks for the tip.
Hey, may I ask if he made the suggestion on a different video about this exact bike or is it off this video ? I’m on the lookout to buy one and would appreciate it if you can share the suggestion. Thanks
The 103/96 is a rock solid engine despite what you read on the internet 😂 there’s a lot of guys that own shops that want you to think their garbage to sell you parts. Sure the early 88s have some issues but the twin cam 103/96 is pretty bulletproof
They really are solid engines, you hear of a 1,000 failures in a sea of millions of engines that have run for years without issue and the focus is on the failure.
@@GixxerFoo that Baxter guy is the worst, or Tman, they have some good info, but if you listen to them for 10 minutes you’d think every single Harley on the road was an oil leaking crank out of spec piece of crap and they’re really not 😂 the other problem is people run to the forums and make a “has anyone had this issue” post every time a part fails on a bike…Harley’s are very reliable quality motorcycles that are mass produced, anything that’s mass produced has a lemon here and there and has parts failure here and there, it’s nothing new.
The 103 is a great engine , just some a few internal upgrades and you’ll be rolling for many a mile
Have a 2012 Super Glide Custom with the 96 cu inch. Gets me everywhere I want to go, who needs the 103.
I have a 2009 FatBob with 103 Stage 4 Race kit, 259e cams and just SE slip-on mufflers. Dyno at about 112/111. Very reliable, pulls like a beast and so happy.
That's awesome! Those factory headers are pretty dang good, they really don't get the credit they deserve. Some good slip-on exhaust work really well, those are very impressive numbers!
I love this my favorite channel on the entire Internet every time something new comes out. I’m here man. I love this channel. I think you’re a great host. Keep up the great work sincerely Spider HAMC NOMADS DIXIE Chapter////I I have a 110 CVO ULTRA with the stage 3 kit”
I'm very happy with my 103 on my 16 Fatboy great torque good performance reliability is solid
Those were some of the best years of the 103!
Damn! That bent shelf is still screaming at me.
Yeah man it’s gonna go!
4 years ago i purchased a 2014 Road King FLHR 103 HO absolutely love this bike. Since switching over to full synthetic in all 3 holes I’m achieving 46 mph religiously. I used to get 41-42 with detergent oil. I had a 2005 Road King Classic before this one. The rider and performance changes they did to the Rushmore series bikes are outstanding. 2013-2016 bikes were Rushmore. 2017 switched to the M-8.
I went with the stage 5 tire shredder kit with the pro tuner 123 hp/ 127tq. I love it it is been on my bike for 3 years works great.
It's a mean kit, guy that works at my local dealer has one on his Road King. You pulled some damn good numbers with yours, what exhaust are you running?
My 2014 Super Glide has the 103. Great and beautiful bike-last year for it.
The Super Glide with the 103 is not a very common item, every single one you find usually has the 96.
I got the factory 103 HO on my soft tail, it backfired allot until got the Screaming eagle ignition module and I went to the Cobra Neighbor haters slip ons..Bike sounds amazeballs but I still get some back fires now and again..Its a Gold Hard candy Custom..Love this bike!
Is the backfire not good I have a 14 SG with ho 103 and I get back fire every so often not much though
I have the 103 from 2015, and I put the tire shredder kit in it. It tops at 117 horsepower and 127 foot pounds of torque.
I gotta say that Tire Shredder Kit is bad ass, it's really impressive with a good exhaust and tune.
I got a 2016 heritage softail with 103HO. It’s got more than enough power for me. I don’t ride a harley to be fast anyway. I just never had a desire to mod engine and compromise the reliability to be faster. That 103HO will do anything I ask it to do whether it’s climbing a mountain or crossing the country. Harley got it right with the 103HO and I’m gonna leave it alone.
It’s all in the heads ! My 2015 RK I used my stock pistons and sent the heads to zippers performance for there mildest CNC port they offer called 1.8 for the slightly larger intake valves 700$. Put it back together with.030 head gasket and heads decked made it 10.25 comp. I already had Andrews 57h cams & powervision with cobra power port headers & SE street cannons. So this is the cheapest big gain set up you can get. & never even had to remove my cylinders. Had it dynoed with the powervision & ended up with 108 hp & 116 TQ & a very happy customer 👍 I did it with 14000 miles on it.
Forgot to add I did it all myself including the cams a year earlier so no labor costs
Doing it yourself is the way to go! That's really impressive numbers, the twin cam engines really respond well to compression. You made some big power on the cheap, Zippers does really good work too. What was the turn around time sending your heads out?
GixxerFoo
10 days in February which is there busiest time
www.bigboyzheadporting.com/TwinCamComp.htm
Wanted to add this link that helped me figure everything out as for what I wanted to accomplish. That plus a lot of other research on various Harley forums
Very true harleys absolutely make there power in the heads, but those heads need the right supporting parts to be able to make that power. They cant do it alone
That's very true, having some compression never hurts either.
My 2017 Dyna Low Rider S is the 110 twin cam. Love it. Last year of the great one
That's already shaping up to be a special bike, they are already highly desired. I would hang onto that one!
If you take it to over 120 + rwhp and torque ..get rid of the compensating sprocket and clutch and replace the compensating sprocket with a solid plain replacement sprocket and a Baker King Kong Clutch or it will all self destruct ..been there and done that twice ...the last time it twisted up the fly wheels .. Was not a pretty site . used the latest screamin' eagle compensating sprocket and screamin' eagle clutch plates that shattered in to gravel of pieces parts and parts pieces
Hello, Had the Woods TW222 cams installed
in my 2013 dyna street bob. They made a huge difference. Needed to run the autotune in my fuelpac. Very happy. Thank you for your advice.....Gary
That Wood is just so hard to beat for me, I bet it feels like a new bike now! I am really happy to hear you're enjoying it! Let me know how it runs after you get your auto tune done and get it dialed in some more!
@@GixxerFoo . I auto tuned the bike and it runs amazing. Very happy. Does feel like a new bike. Thank you for the great advice....Gary
Not a problem, anytime!
Good background info on the 103. I run a TC88 but I like that 103 for sure.
That 88 is a solid motor, it would be nice that 103 bottom end was built like the early 88's with the Timken bearings.
@@GixxerFoo I agree. Mine's a '99 and carburated; Timken is in there. It could stand some more power though. Right now it has a k&n air filter, re-jetted stock CV carb and true duals with some CVO 110 slip-ons. Runs solid with over 50K miles. Subbed..
Sounds like you got the setup going on the bike! I appreciate the sub!
Very informative video 👍👍
Thank you! I appreciate it!
Old video but...picking the wife up a Softail Tuesday with a 103. 6600 miles on it. How much do I need to worry about the cam chain tensioners? I feel like with the 96 people don't worry about it but with the 103 they do? Did Harley go backwards with this?
Have a 103 Heritage dyna tuned. Appreciate the information of the other options available and estimated cost. My 3rd video watching, 3 is a charm: subscribed. :)
Another top class info video.
The 103 is my fav engine.
Many thanks! The 103 had all the improvements from over the years, the numbers on paper don't look much different than the 96. But if you ride one you'll feel the difference immediately.
Look at that bow in that shelf…daaaang.
😆 that shelf l swear made the channel famous. Lol it's been replaced since this video was made.
I bought the 2015 Road Glide Special out here in Cali and with the smog is was a DOG! Ran hotter than hell, didn't get 200 miles on a tank and had no throttle in 5th & 6th gears.
Purchased the Screaming Eagle race tuner. Installed a Roland Sands intake and Reinhart slip ons'. Took the stock exhaust off, emptied out the catalytic converter chamber and reinstalled it. Had to take it to Arizona to have it dyno tuned. Like a brand new bike. 92 hp with 113 torque. Runs way cooler, 240 degrees when it's 100 degrees outside. I get 230 to 240 miles on a six gallon tank. And of course, it's not the fastest bike but nobody leaves me in the dust. This thing is a rocket ship recliner. These days Harley is begging me to trade this in on the M8. Thing is how do I take the Cali smog off this thing and pump it up like every other Harley I've owned? The stage kits are crap and full of problems. These things eat, breath and fart. You improve this on the Harley it's like you have a brand new bike.
Thanks GixxerFoo straight up advice I just got a 2015 RG with only 6000 miles on it and I'm looking at giving it some more power trouble being down here in NZ parts are way more expensive.
Thanks again from NZ
I appreciate you watching and your support! I bet you got some beautiful riding country around there, does it already have the stage 1 done or is it still stock?
@@GixxerFoo Thanks Brother yes we do have some great ride's down here but usually if you ride far enough there's always somewhere great to ride.
My RG has Monster Round slip-ons I'm not sure apart from that it was imported from the States.
All the best brother
My 2014 streetbob came with the 103 I am a big fan of the 103 the last three bikes I have owned had 103
The 103 is a very nice motor, it performs very well in the Street Bob. I was impressed with the one I rode that had a 103, it was cammed and it pulled hard out of the hole.
I put a woods 222 cam and a tune and it runs great! Dark Horse compensator is a must
That Dark Horse makes a huge difference!
Another great video, looks like stage IV tier shredder kit for me, now to get the labor $$ cost from my dealer, thank again, subscribed
Thank you for the sub! You'll love that kit, the salesman at my.local dealer has one installed on Road King and it hauls.
First modern twin cam 103 with the cruisedrive 6 speed transmition was first introduced in 2007 police engine.
That's true, it wasn't widely available to the public until 2010.
Nice informative class on the 103!
Thank you for clearing that up, the most explanatory video on the 103's highly appreciated,
On my 2015 Road glide 103 I went to the tire shredder kit the 110 it's like holding onto a bull so impressive so exciting to ride, I don't know I could be wrong but I feel like my bike has more balls than the 114 117 and even some 128 LOL am I wrong, my torque is 123 at the rear utilizing screaming eagle super pro tuner, using Vance & Hines headers and cross pipe.. on the clutch running the scorpion clutch
You are welcome! I wouldn't doubt it pulls harder than bigger inch motors, you've got a the right tuner and a good exhaust setup! That makes a huge difference, the salesman at my local dealer had the tire shredder on his Road King and it hauled ass! He was in his 70's and a real hardcore rider, he went out with a heart attack riding home one day.
@@GixxerFoo wow what a way to go well God bless his family and Godspeed to him!! Really appreciate all your videos. Great information second-to-none thanks!!
Hell ya! Now we're talking 103!
The 103 is an awesome motor, it's really impressive what just a cam swap can do for those bikes too!
I ordered from Harley-Davidson in 2013 the new cases the screaming eagle 4.070 Pistons jugs the CNC heads and the 4 3/8 crankshaft. I added fueling cam plate oil pump and lifters I added Andrews 67g cams I have the crank trued and welded I had the jugs done and my bike makes 126 horsepower at the back wheel and 118 ft lb of torque I changed the primary to the screaming eagle 315 and she'll do 145 comfortably with the original five speed this is the engine I put in my 01 road glide to replace the 88
That's a very nice engine you built! Andrews makes some awesome cams for Harleys, great company and they also grind cams for many others as well. You've got some serious power on that bike, I bet it's a blast to ride!
@@GixxerFoo one of the stupidest engines I've ever built the bike doesn't weigh anything does 10 second quarters I only weigh 160 lb myself total idiocy thanks for noticing.
@@randylucas2458 Sounds like my kinda engine! 10 second quarters on a Harley is a hell of a ride, hope it's not too squirly out of the hole!

Cheers mate🍻
My question is how do I find out if my 2016 Street Glide Special 103 has H.O stock cams? Thanks for all the informative information and videos
The only way to know exactly what cam set is in there is to pull the cams out, but if you just want to know if it's stock or not there is a way. You would need a tuner that allows you to view the intake valve open/close value. The open and closing values for the stock 103HO cams are 02 BTDC and 30 ABDC (before top dead center and after bottom dead center) this tells the ECM when to read the MAP sensor. If those values differ than the cams are likely not stock, that's the best way I know give you an idea if they are stock or not without pulling the cams.
@@GixxerFoo you are the official H-D savant!! I appreciate the feedback and the informative videos when making hard cash errand decisions when upgrading my H-D.
I'm confused. Did you buy this used or brand new ? Did they use 2 different cams for that year and model because I have the same bike (bought it brand new)
@@gaknskk I bought mine new as well, the only power upgrade I’ve done so far was have the Sceaming Eagle ventilator elite installed. To compliment my Rhinehart slip on’s.
Love my 103 ,my uncle wanted to borrow my wide glide , told him he would have more chance getting Christina agrulra in bed than borrowing my bike
Any luck with that Christina thing?
Just say it in English Christina Eagles . Lol Aguilera 🦅
103 is solid and can make decent power while maintaining longevity I put a 103 kit on my 07 wide glide 54k miles only thing that shit the bed was my fuel pump at 50k not a big deal to replace though
103's make a great power stock, even when you convert a 96 over with the stock cams the displacement makes a difference.
When I bought my 2013 Road King off the showroom floor it had a stage 3 kit and an aftermarket exhaust from the dealership in Victoria, BC. It would snap my head back when I twisted the throttle on the freeway. Does the stage 3 kit mean it has 110" cylinders? I need to buy rings for the rebuild, what size rings would they be? Thanks for the vid!
On the 103 there were so many different variations of the stage 3 kit at that time it would be hard to tell without tearing the bike down measuring the bore. Since it was done by a dealer you can have your Vin number run at a dealer and they will be able to tell you everything done at a dealer on that bike. At that time there were stage 3 110 jug kits but also high compression stage 3 kits with cams too.
@@GixxerFoo thanks, the dealership is out of business. I had a wreck several years ago and it's slow going getting all the parts together that were messed up, I'm still saving up and looking for a frame. I have the engine torn down, ready to put it in S&S cases. What would the bore be for the 103 and 110 respectively? The dealership is elusive about the answers (I think they want me to just buy a bike from them, but I have an '83 sportster that will do for now.)
I just upgraded my 96 to a 103 and did a stage 4 with perf8ct fit cams and lifters
i enjoy my Twincam 96 the way it is , yes it's a noisy engine but all Harley engines got some noise . You just need to change the oil every 2000 miles and use a good quality oil and filter. Don't be afraid to use a 60 weight full Synthetic oil for extreme hot temperatures.
Nice work Gix!
Great information! I have a 2012 Roadglide with the 103. The kits, like you said unless you go all the way are less than impressive. Currently i have stage 1 with 2 into 1 exhaust and SE street tuner. I’m looking to upgrade with a Thundermax ECM, and a woods Tw-222 cams. This should net me about 97-100 hp right?

@@tonyc2912 Ok i’m just wondering if 4grand is the going price for out the install. , I’m in Boston so shit $$$$$$$$ lol.
A that works at my local dealer has a Road King with tire shredder. It's worth the money, his bike is fast and it runs hard.
What about performance upgrades for cvo 103 like thiner head gasket for higher compression and Cam upgrade .what cams would you recommend not looking to go with se more aftermarket looking for performance and a little chop.
Thx. Love your videos
The CVO 103 is a very interesting engine, it's basically a stroked 88. Here's a video on the SE 103 th-cam.com/video/xQbzkJawKvM/w-d-xo.html
I just bought a 2013 softail slim with a 103.. it has 85k miles on it.. I figured Id do a 110 kit, cams, and cnc'ed heads. I figired a cam plate, true and weld flywheels and timken conversion also. But Im wondering, will it be ok to do this without actually rebuilding the crank ?
If you plan to go that far with the bike and the mileage that it has on the current lower end I would go ahead and do the crank. That's a lot of miles down on the bottom end, planning on a cam plate you'd likely find the run out on the crank is too high. You'll need run out ideally at .003 or less with a billet race cam plate.
In the market for a Harley right now. The 103 is plentiful and at a good price point for me. Specifically in the 14 streetglides and up. However, the M8 bikes are there too.What’s your opinion, I’m currently set on a low mileage 2021 street glide and ultra glide. But I can save a few grand getting a 2015 103 with about 20k on it.
Love your channel and your videos. Looking to upgrade to an Ultra Limited. I’ve noticed that the ‘14 models are quite a bit cheaper than the rest of the Rushmore bikes. Is there a reason and what should I look for?
Thanks for the information. I’ve really learned a lot watching your videos!!! What’s your thoughts on a S&S 124 upgrade from a stock 103???
I know this post is old but here is my question. 2013 Tri Glide. Will be installing woods 222 cam. S&S High volume oil pump and cam plate with S&S lifters with adjustable pushrods. DK customs 606 high flow breather with factory cat deleted headers and gutted VH pipes. What numbers should I expect to see out of this setup? Power vision tuner. Is there a better woods cam for this setup? Trying to stay with drop in cam setup while gaining torque along with some top end speed. Tavel in the mountains and out west pulling a trailer at times. Will be making the Sturgis run next year pulling trailer. Trying to also keep a reasonable fuel milage.
Wood 222 is going to be the best all around bolt in for your setup, that cam really excels in heavy bikes with the torque curve and top end power. With a catless factory head pipe and V&H mufflers and a power vision canned tune for the setup you should land around 90 to 95 horsepower and north of 100 foot pounds of torque.
@@GixxerFoo Thank you brother, your channel is a wealth of knowledge. It is great to see someone with the passion you have for what you do.
I have a Two 103 touring bikes..2015 RK, 2016 SG Special....love them. I also have a 2019 RK Special and a 2019 Fat boy with 114 M8s. Yes the M8 have more power but I still love my Twin Cams. Let's face it HD has to make engine mods. Other than paint how can a HD be improved. One of my Twin Cams has 78k miles and she runs like a dream. The M8 blow oil smoke sometimes and you definitely smell oil burning on start up. Most of my family think the engine sucks. Only because HD has not come clean about this engine. First the oil migration to the primary and now HD is on their third oil pump improvement....not to exclude the new M8 oil filter they rolled out....why? My two M8 only have 6300k miles between them so time will tell. They both are getting the new SS came plate and oil pump in Oct 2020 when I have time to replace them.
Have you had your M8's in for all the updates? I saw they started drilling the case on the primary side and putting a vent/return tube in there. Seems like something they would of caught in development. I've talked to several people that came from a TC to an M8 and they said the same thing.
I have a 2014 Electra glide ultra classic with Reinhart exhaust and a screaming eagle high flow air intake, it has the oil cooler and it putting out 91 hp with 111 lb ft of torque is there a way to tell if this is stock with tune only or if the put a cam in it?
I also have been told my bike is quick having the 2 into 2 exhaust and louder than the stock harleys coming from the show room floor
103 was not released in 09 because my Electra glide CVO came with A screaming eagle 103 in 2004 this is the grandfather of the now street glide
The 103 during the 88inch era was only in the Screamin Eagle CVO bikes. The replacement motor for the CVO was the TC 110 when the 103 made it into standard production of all models. But at that time the 103 you're talking about isn't exactly the same as 2009 103. This 2004 103 shares much more with the 88 in that time period.
Michael Crowley you're right I also have a 2004 Screamin Eagle Electra Glide he was wrong on his dates
I’m considering getting a new 1200ns, FXDL with a 103, and a softail S with a 103. What would be your pick? I’m leaning towards the Dyna but the 1200 is new. However for long Texas straightaways the extra power might help.
They are really great bikes in their own respects, I might be a little biased cause I really like the Dyna Low Rider. A Softail Slim is great riding bike but it does sit very low to the ground and doesn't have much cornering clearance. The 1200 is a fun bike, I have a 2016 1200 custom and my wife rides a 2017 Sportster 48. But if you're running down long highways it's gonna get real small after a while, I'd say the Dyna would would be my pick. The Low Rider is like a big Sportster, it has room to stretch out and it's a lighter big twin but it will still ride good down the highway.
I have a 2012 electra glide. All i did was put in a decatted stock header pipe, cobra 909 uppercut slip on mufflers, big sucker air cleaner, dyno tune and andrews 57h cam. Makes 97hp 107tq. Sold
Those factory headers really don't get the credit they deserve, they are really pretty damn good. Once you get that cat out and add a good slip on like you did.
My ducati multistrada has 150 HP ONLY weighs 480 pounds and all I do is push the button !!!!😄😄😄😄😄😎😎😎😎🍺🍺🍺
Those are fun bikes to ride! Ducati just has that Italian refinement, they are unique in the feel and ride like the Harley. You ride any Japenese bike and they all feel about the same.
@@GixxerFoo the first 92.000 miles have been good , I think I will keep it !!!!😎😎😎😎😎😎😄😄🍺🍺🍺🍺
Wow, dang you ride the crap out of that bike. I haven't heard of a Ducati with that kinda mileage before, never doubted they could do it either.
Good information well presented. I’m currently looking to get my first ever Harley and I’m looking at a 2015 ultra limited with the 103 engine only concern the one I seen at a good price had 30,000miles on it, what would your views be on that mileage ? Or should I go newer and get the 107 or 114 m8
Thanks in advance any help would be appreciated
I like the late model twin cams since that's where they got it right in my opinion. Now the early M8's up to 2020 have some issues with oil sumping and piston oil jet coolers coming loose. With that twin cam at 30K I would just have the tensioners checked and make sure they are still in good shape. With they hydraulics they can last up to 50K miles, but better safe than sorry.
@@GixxerFoo thanks for the reply and info much appreciated. Are these 103 Rushmore’s engines good for high miles then? I’m not a fan of the sound on the new m8s plus the stories put me off Aswell on then 107,114’s.
It’s more for just long rides and slow riding not for speed at all
@@boylejohnstone1 on a different note my 103 lost a can tensioner and wiped out the motor with 26,000 miles. My 2017 m8 now has 76,400 miles on it with only oil changes and a stator. My 82 shovel swallowed a valve at 29,000 miles......my 98EVO is still running along with 102,000. I work on 5 M8s that i have vented heads to atmosphere like i have done with every Harley from 76 till 2020. M8s we do run 4 dots low on oil stick. And vent crankcase to atmosphere ( 8 bucks to do not 100+) So i think the m8:engineers also run too much oil. Maybe why you dont see many softtails stumpping...🤣🤣🏝
If you are looking to re-build an engine with the goal of power, it'd be better to score a 110 engine and use the 117 'drop-in' cylinders as the heads are a much better casting. Get the heads fitted with bigger valves and port them and your numbers can be over 140 in torque and horsepower. If it is a rubber mount bike though you will have to upgrade the engine mounts in order to stop the dreaded 'death-wobble'.
I've heard of the death wobble and know some guys who had monster S&S Dyna Engine builds that experienced it. There are after market stabilizer links for the engine mounts out there and they do wonders!
@@GixxerFoo Yes, but stabilisers are not enough when you get up to high power levels - you need different mounts. I use ones from Big Bear Performance as they offer a little sideways adjustment on the front mount that enables you to get the wheels aligned properly.
My Sporty's mounts were old and buggered so I fitted ones from Drag Spec as they are firmer and the handling on my Sporty is great now. If you were to see my bikes you would be in awe as so much is changed or altered..... my brother in law says it's easier to remember what parts I haven't changed, modified or re-engineered. I have had the bikes 11 years now and it is a constantly evolving situation. My Dyna has had over 3250 spent on it including original purchase price (new) and the Sporty about £10k but that one was second hand.....
I just bought a 2010 Ultra Classic 103 and it's leaking a few drops of oil every day. Oil and trans fluid are fine. It looks like it's coming from where the pan bolts onto the bottom of the motor. This is my first Harley. Any ideas where it's coming from? Do they have a reputation for leaks?
would it be feasible to replace the EFS with a carb on a stage 4?
Quick question, are the 103 heads a direct bolt on to the twin Cam 88
They actually will bolt on and they are much more efficient. You will however have to use the late model intake flanges.
@@GixxerFoo do you think it would be worth the expense ?
(Slowly learning)
And would it Better the motor as far as longevity ?
If a cylinder kit from 103 to 110 is chosen, does it not also require a change of cylinder heads, for larger ones?
i have a question, i have reaper 574 cams, big bore to 107 10.75/1, 55 hpi tb, ported heads, tmann no loss air filter and two bros 2 into 1 exhaust. it dynode at 106/112. what cam would make this setup better?
You've got a nice setup with some good horsepower and torque, that's about right inline with that cams performance. I would check out Wood Cams, I am not sure what year your bike is or what it is (dyna, softail, tourer). Assuming you have some upgraded valve springs with the head work you can actually go with 555 or 222 from Wood. They work with stock springs but they love some compression. TW-7H is another monster for your bike, depending on where you want the power to come on anything from Wood will crush your current numbers.
@@GixxerFoo its a 2016 sg, yes it has s&s valve springs, s&s cam plate and pump. i was thinking about tw999 or tw999-6a.
thank you
@@GixxerFoo what do you think about this cam for my bike Wood TW-999-6a
I’ve been riding a TC 88 for 19 years. Seems like back in the day when I bought the bike Harley-Davidson offered a kit that could take the TC 88 to 113. Any idea how that measures up?
Brad I bought a new ‘02 ElectraGlide and at that time they only offered a 95 kit, which I had the dealer put on .. the SE models in ‘04 had 103s but I don’t believe that was offered until a few years later
Have a 13 hertiage with the 103 love it
Very nice high torque motor, the displacement really improved those motors over the 96.
I wanted to know would it be a good buy for 2014 street glide 103 with 64K miles on it? All I know is that it has a d&d 2 into 1 exhaust.
I think that depends on what the motor condition looks like. Ask the seller questions. Test it. If you think its not worth the price, still get it, but only if you are able to get it for what its worth.
Did the 2008 police bikes have a 103?
Yes the police bikes had the 103 in 2008, the police bikes got that 103 years before it was even an option on production bikes.
Hi, a little off-topic question (but maybe not so much).
Based on your I see deep knowledge what do you think about the flywheels scissoring; on the late TC103s it's still an issue to be concerned of?
Especially if hopped-up or brought to 110
I tend not to do clutch drops or lug the engine, on the contrary, I like to wind it up when the road is right
It hasn't seemed to be wide spread from what l've seen. When it does happen it's usually someone waaaaay overbuilding an engine and riding it extremely hard. There are a lot of Twin Cams out there with with well over 100 horsepower reliably.
@@GixxerFoo Thank you very much! Great channel you have and you are very interactive
Not a problem at all! We definitely appreciate your support over here!
I was worried two months ago when I bought my RK from Harley having 70k on it! But they promised me that this 103 was solid! But the valet train can be noisy
103's are really good motors, they got the 103 right and then went to the M8.
When bigger cylinders and higher compression pistons are added to the 103, would these things effect the dependability of the bottom end. Crank, bearings etc.? Thanks, I enjoy learning any new information you may impart upon me.
It's always a possibility but a lot of that depends on how hard you are on the motor. If you just ride it and not beat on it constantly, take good care of it, it can be quite reliable.
Excellent information! In my opinion, best knowledge about Harley-Davidson engines in the last three decades. A quick question. I am considering buying a Tri Glide. Choice between a 2017 or newer M8 or going back a few years earlier to a 103. It looks like upgrading a 103 to get some more torque is a great option. Problem is I could get a 2017 used for only $1,000 more. I'm not a speed freak, I'm just concerned about the big three wheeler moving when I need it to. What would you do and why? Thanks for any reply
Thank you! The trikes really needed the extra power of the 107 and 114 M8's, but the 103 does very well and a cam swap will really get the horsepower and torque where it needs to be to really pull a trike. Now the 2017 M8 had oil sumping and oil pump issues, I would take the VIN to a dealer and see if it had any warranty work done. 2017 engines with the original oil pump design had the issues and Harley replaced those with a newer designed unit under warranty. If you are able to verify that I would go with the M8. But the twin cam 103 is tried and true, they got the issues with the twin cam worked out on the 103 and of course they changed over to M8 shortly after. My opinion is the 103 is less likely to have an issue vs. the 2017 M8 which was the first year of that motor, I've had some bad experience with the first years but that's just me.
2014 street bob has a 103 as well.
What cam would you suggest if I was gonna change out my 255 e in my 2007 cvo screaming eagle 110
I have an original 88 2005 RK that was build by the previous owner to a 103 Screaming Eagle(old). He put a Screaming Eagle 6 speed transmission. Cams seem original like on the 88s. He did put a SE intake.I have replaced the cam plate with a Feuling cam plate with hidraulic tensioners and new larger fuel pump. So the engine is far from original. Question is: When I will need to rebuild the top end, with what can I replace it with? I don't want to go back to 88 and I don't want to bore out the cylinders . Can I use something bolt on? Cheers! P.S. I am not a mechanic and english is not my first language :)
If it's a 103 it's likely got the stroker crank, so a new 95 inch top end kit to freshen it up would work great.
@@GixxerFoo thank you so much!
Hey anytime!
2014 FXDB w/ 103
Can anything be done to save the 110 kit with the CVO heads?
I'm not sure what you mean?
I have the 110 kit (still in boxes) you said to stay away from. Can I change any of the components (heads, cams, pistons) to make it work better? Purchased it from a guy that sold his bike before he had it installed. Paid $800 for it and not sure if I should cut my loses or try upgrading the kit.
I guess it was a wasted $800.
If I go for the 110 package can the stock crankshaft handle the power? Seams to me I might as well go for the 120 st crate motor??? Love your videos keep them coming!!!
If you keep it mild and don't beat on it the stock crank will be alright, they are pressed cranks so biggest thing is just not lugging the motor. I would get at 120R before the ST, the ST is the same engine as the R but the ST has a milder cam.
A little off topic, but what is your opinion on the stock CVO 110 Twin Cam, not an aftermarket 110 kit? I have been reading horror stories on some online forums about the lifters going out. The one I just bought has 41,000 miles, kind of a lot for a bike and I am hoping that any issues the 110 has have already happened and been corrected. What are your thoughts? Thanks for the great videos.
I heard of that happening but it was kinda like the cam chain tensioner in the 88. It didn't happen to every bike out there and depends who you talk to it was maintenance related. Personally l wouldn't be too worried about myself.
I should have read a LOT more about the 88 because I found a decent LR with the 88 with everything I wanted on it---low mileage, rack/bags/shield/engine guard/back rest/ and good paint and not bad for rust. It has been one problem after another. Over and over , thousands spent just to get it running AND haven't even't replaced the chain tensioners yet. Such a disappointment. SO, spend some extra money and buy a late model 96 or the 103. Even a nice 88 with low mileage COULD be a real POS.
Then 88's were really hit and miss, some were flawless and others had all the known issues. The later year 88's weren't too bad but the 96 had the issues corrected by then.
Cual es mejor el antiguo 103 cvo o el moderno 103 ?
Been waiting 12 months for the 110 tire shredder kit. Undisclosed Parts are missing.
How about video on how to swap out our twin cam for M8 say 135cid
Will tire shredder 110 kit fit my 96
Technically yes, but Harley will only warranty it installed on a 103 🤦♂️.
What's your Honest Opinion on the Hammer Kits for the Sportster?
They are absolutely second to none, those are some of best power you can buy out there for a Sportster.
I have a twin cam 88 softtail deuce.And I raced my buddies 114 fat boy and surprisingly he did not win
What do you have done to that 88? I love the 88's but just pipes and air cleaner won't hold a candle to 114 M8.
@GixxerFoo I picked it up with 40k put exhaust on it and updated the timing guides and oil pump along with s&s adjusted push rods. Not sure if someone else did heads or something before I got my hands on it! But trust me I was very surprised to edge him out. He's fatboy is stock though so I sure that's holding it back Maybe?

If you get rid of the screaming eagle cam and get a Andrews cam and a better tuner you can slay those numbers
That's the key to it right there! Screamin Eagle cams have nothing on Andrews.

@@GixxerFoo yes 103 to a 110
That Stage 3 setup makes really good power over stock. The stage 4 is a high rpm kit, the stage 3 keeps the power in the middle. Depends what rpm range you're looking to ride in mostly.

My 2010 has been a pita with it's sensor issues. Been dicking with it for a couple weeks till I gave up. It's at an indy shop now to try to figure out some sensor based issues @ $140 an hour. Woohoo!
