Mikuni Carbuertor SUCKS gas / Carburetor Swap To CV Carb

- When I got this bike, it had a Mikuni flat slide carburetor on it. While a Mikuni can be a lot of fun with it's peppy performance, you certainly sacrifice a lot in fuel mileage. Well... I'm not much into being the fastest one out there... I'd rather just get to where I'm going while just enjoying the sights. But not for 30 mpg or less.

im just a backyard do it yourself guy. No official training. I went to the local expert in town when i went to swap carbs out. Good ole boy, been working on bikes for longer then ive been alive. Has a repair shop and his own parts shop. He helped me select the mikuni carb you are talking about. I experienced a loss in fuel mileage and a terrible noise. He explained how a flat side carb works, then pressed in on the slide and the noise disappeared as promised. Then he took and adjusted what i believe is called the accelerator pump rode so there was a space the width of a nickle between it and the throttle lever. He explained that from the factory the rode rides on the throttle lever, so every bump that may make your had twist even the smallest amount it dumping a bit more fuel in which is just going to be wasted. Since my bike is a hard tail, every bump in the rode had this effect on my bike without me even realizing it. After that, he took my pilot jet from a 25 to a 22.5 and took needle adjustment shim up a notch allowing my need to go further down. Now my fuel mileage is about back to normal and i still seen 6 hp and 8tq gain on the dyno. This is just my experience, may be something to play with yourself.
well that and throttle control, just a mikuni carb added onto your bike wont make it burn the wheel. staying out of the power band when im just putting around helped me out too
sorry to be so off topic but does someone know a trick to get back into an Instagram account??
I somehow forgot my password. I love any help you can offer me
@Carmelo Bruce Instablaster ;)
@Jonathan Miller thanks so much for your reply. I got to the site through google and im in the hacking process atm.
I see it takes a while so I will reply here later when my account password hopefully is recovered.
@Jonathan Miller it did the trick and I now got access to my account again. I'm so happy!
Thank you so much, you really help me out!
There’s a fine line between performance and fuel mileage. If you dump too much fuel you’ll take the engine out. Too little fuel you will over heat the engine and take it out. My 2003 sportster 1200 has a CV carb on it. Was always just slightly a little bit lean from new. If you left the choke out 1/8” it ran perfect. So this year I finally took the top off the carb pull the needle out of the slide and install a .025 thick washer on needle and reinstalled. So now engine gets slightly more fuel. I adjusted the idle mixture screw to about 2 1/4 turns out and set the idle at 1000 rpm. Runs great. Oil temp in tank was 195*F at 90*F air temp. Now it runs 10*F cooler at 90*F/185*F. I also use 20W50 Amsoil. Mileage stayed the same and the mid range performance is better more responsive. Fuel mileage is about 60 mpg (Canadian mpg) US probably about 50. Pipes and air cleaner are stock from factory. Scooter tramp Scotty had a video on the carb. I followed his advice worked out great
I had a '00 1200C , stock except for mufflers and a/c and eventually, Screaming Eagle hi compression pistons. Ran great , but not til I gave it a valve job and upped the jets in the carb... she loved the fuel... still got about 50mpg US. My 88 1200 had a mikuni, cams, head work, Supertrapp, fast bike but 30ish mpg.
You mentioned Tatro Machine a couple times. In the last couple years Tatro Machine has become a popular TH-cam hangout for bikers.
Nice video. I've got a hsr42 mikuni on my 1974 rigid shovel and I'm very happy with it. Super response, run fast and at normal rides it doesn't use much fuel. I will not swap! Cheers from France!
Check the jets on that CV, should be 42 pilot-175 main. Change the needle to H-D Part No. 27094-88 (Old sportster needle) to get rid of the off idle lean condition. If not already done pull the idle mixture cap and adjust for best idle (start at ~ 1 1/2 turns out from all the way in). When turning mixture screw all in to bottom be gentle. Should get almost 50 mpg and good acceleration throughout the throttle range.
The Mikuni is a great carb. too. Needs 17.5 pilot jet-160 main(HSR42) 175(HSR45) and a 50 accelerator pump nozzle.
Hope this helps, these are Joe Minton's Tips, He wrote the Mikuni tuning manual. You can get it free online.
Now I know why they call it a steel horse, it's that damn tune
Exactly! I think it sounds like the cadence of a horse cantering when idling and galloping when accelerating. Best sound ever!!!
When the engine backfires at the intake the engine is running lean, very lean, when it backfires through the exhaust the engine is running rich. Very rich.
Totaly wrong my friend, I run a Mikuni HSR on both my HD's, one a 42mm and the other a 45mm both around 50mpg on a run. That thing just needed setting up right.
Yeah, the only real disadvantage with the Mikuni is if you're going up and down in elevation a lot.
@@wesd3370 the guys from hammer performance claim they've had bikes with both carbs at elevation and one ran equally as bad as the other.
@@masterofnonetv8361 Totally. My main point was just that aside from the slightly larger Venturi, the only real difference should be that the mikuni doesn't have a system to adjust itself for elevation and that a poor gas milage issue is likely just related to a bad tune.
I’ve been wanting to put a mikuni carb on my evo! Thank you for the video
My buddy just traded his mostly stock Sportster for a super-customized, very high performance Sportster. I noticed his carb didn't look like what he had or what I have. Now I recognize it, it's the Mikuni. He is constantly complaining about how his acceleration in the first few gears is like a rocket and he still can't get used to it. He didn't do his homework and bought the rocket on an impulse. Now he has a tiger by the tail. Be careful of what you ask for.
Another great educational video. Thanks!
Nothing sounds like a carbureted Harley awesome 👏. Great video!!!!
man you ain't lyin'...ugh!
Sounds like there is a cam in there. With the Mikuni, ignition and pipes, it wouldn't surprise me. I have a bone stock 95 FLSTN. Doesn't sound anything like that, pretty sure it is not just the pipes. I have a Mikuni in the drawer never take time to put it on. Rethinking that now.
Is your 1995 the same color as the 1994 because i have the exact same 1994 flstn model as this guys i was just wondering from what im told the 1993 moe cow flstn then the 1994 flstn bull hide is the 95 anydifferent
FLSTN, four years of production, 93 Moo Glide Black and White, 94 Birch and Silver, 95 Black and Charcoal, 96 Dark Green and Charcoal. Then they quit making them.Today's FLSTN is the Deluxe. As I was buying mine, new from the dealership, they told me, we can't call them Nostalgia any more they are the "Special". There was a motorcycle parts company called Nostalgia (might still be around). Harley was getting a reputation for taking company names and then making the original company stop using it. Hog Hollow was another parts company. Rumor has it HD stole their name. They had to change their name to Fog Hollow. Nostalgia (company) must have taken quick action and HD lost so we can't ;) call them Nostalgia's any more. But I still call mine a Nostalgia, I like it better than "Special".
Thanks. The last bike that I had before this one, my '05 R.K.Custom was a '51 pan... Needless to say, it's like comparing apples to oranges. I wish that I your garage!!! I don't have anything like that to turn wrenches and living in N.J. makes it a pain in the ass in the Winter.
Anyway, someone dumped about two cups of sand in my gas tank. I had no idea for about a thousand miles. It sandblasted the CV carb and made garbage.
After much ado, I bought a 42mm Mikuni. Now I too get 25 - 30 mpg. Ofcourse, while the bike was down, I changed out the cam plate & the crappy tensioners and a new oil pump that came with the "Screaming Eagle" was put in.
I'm gonna binge watch your videos before I spend another penny on this bike...! I'm happy with the performance but I definitely am stopping for fuel a lot more.
Once again, Thanks!
Nice production. I get what your driving at. Some like speed, as I was addicted to once, but now it's the long-range rides that beg me to the roads. A well-tuned motor lasts for a long time. Speed comes at a cost. If I want that I hop on the 84 Motoguzzi LeMans 1000. Thanks.
One of your best videos. You keep getting better. Love it! Plus you have shown us how creative your mechanic skills can be. Saddle Tramp Custom Cycles Rulzes.
I don't know about that, but thanks anyway, bro.
I learned to really like the CV 40 carburetors every bike I ever had had ether a Bendix or a Linkard until I got the 02 Twin cam and rebuild the CV 40 carburetor on it. I sold the twin cam to buy a 98 FLSTF and rebuilt that CV carburetor too. I hate S&S carburetors I never had one on my bikes but I must have put 40 of them on others guys bikes for them they are a pain to get set up the first time.
I owned a 1975 Kawasaki Z1-900 which I installed four 32mm Mikuni's. I now have a 2001 Kawasaki ZRX1200R which sports 36mm Keihin Constant Velocity carburetors from the factory. Before you guys give my rice grinder a hard time; I Love World Superbike. I love Harley Davidson cruisers too; I am a motorcycle man.
Yay another guy that’s sports and tourer and chopper enthusiasts all things 2 wheels love from Scotland
HOWDY SaddleTramp,
Without saying so - one way or the other ...
I will assume that the MIKUNI & the KEIHIN CV-40 both "fit" the same identical INTAKE MANIFOLD ?
I got a MIKUNI Carb on my 100ci RevTech engine but have always been a BIG fan of the KEIHIN
I tune & purchase my CV-40 parts @ www.CV-Performance.com
Thanks for your documentation & your YOU-TUBE Video

My lord, your home just sounds like my 1977 superglide! I referred to the sound like horses galaping! I don't know how ya spell it but ya know what I mean...
Great video man. I really enjoy watching you wrench and explain.
17.5 pilot, -98 needle, 50 accelerator squirter will get you the most economical fuel efficient HSR 42 possible. I tried that combo but at best was able to get 42 mpg. Went back to a CV40 and am back to 55mpg. Plus it runs better in my opinion
Thank you for making this video. I was undecided about removing my Mikuni carb. I just want to ride not worried about speed. I bought a bike that already had the Mikuni Carb. i just ordered a CV carb. cant wait to try it out.
Have you done the change over? I am also going from a Mikuni to a CV, and I am wondering if there will be any changes I have to do. Thx
Haa! good job my brother! Yer perseverance pays off with the joy of success and the (way obvious!) satisfaction you get from that well behaved and great sounding engine!
So change your jets not the carb
It does not matter on my ride. I do not get any worse with the Mikuni than I did with the stoker. Thirty-ish has been the norm for me over 17 years with the bike. I ride it like a stole it is why.
Well done, exactly right about the mileage as well, but I am a big fan of mikuni carb, they are very consistent.
I like the Linkert on my 57, in the 90's we'd hit altitude an everone was spittin an poppin. I just gave her a couple clicks an of id go! New sub an appreciation for dumpin twin cam
Thinking about putting the stock exhaust and pipes on my twin cam 88 fxdwg.
I don’t need the loud noise and be nice if the mileage went up.
I get 40 on the interstate and 50 on slower two lane highways.
Just rebuilt the CV carb on my 2001 road star 1600...gotta tell ya bro... I really appreciate dude's who work on their own scoots just like I do. I've always had a boner for the old heritage soft tails like you got... hopefully one day. My last scoot a couple years ago was in 99 Vulcan Drifter... everywhere I went, people thought I was driving in Indian because of the fenders. I also love how you look like you're off into a rural area and yer house is tucked back away from the road.
The sweetest sound of a Harley is a evo motor
Brian Blair is beg to differ lmao. Personally I prefer the shovelhead
They all sound different than the others . Each motor has it's own sound and we have loved them all. Bon Jovi has "seen a million faces and rocked them all" Harley Davidson motors has seen a million asses and rocked them all !
Unless you own a panhead
Ironhead for me
Apparently you've never heard a Shovelhead.
I've done that dance in my driveway more than once!
Parts here, parts there, parts everywhere....I love to see you make things work how you want! Keep up the dancing!!!!
I put a manuki carb on my harley Went from 35 miles to gal on trip to 52 Around town I got 30 on cv carb My maniki gets around 44 around town
I found out since this video that this motor had some hopping up done to it. That was the main culprit for the poor fuel milage. I made a video about it since then.
IMakuni carbs r senitive little bitches I bout a new one with.the jets n stuff Ended up ordering more Pilot jet n such before I got it right
Wether a lawnmower,minibike or harley, before even starting to swap a carb, complete disassembly, inspection and cleaning is rule of thumb OR you can be guaranteed the carb is coming back off and you're GOING TO HAVE TO DO IT ANYWAY, so why not just DO IT!!!
12:56 - I do this when the wife says we’re having tacos.
Great video. Nailed it with those mad skills!🤘🏻
Lol!!! Yeah that's my taco dance too. Lol
I as a Dutch fxr evo rider love those video's,also ride a hardtaild kawa z 900 .
I have an HSR 42 Mikuni on my 95 flstn and get about 38 miles to the gallon Andrews 27 cam Big Bore Kit Vance & Hines Longshots crane hi-4 box under the seat
You're a better man than me then. I guess the main thing is that I don't know mikunis like I know CVs.
@@SaddleTrampTV what size Main Jet was you running in that Mikuni? I'm running a 175
@@SaddleTrampTV of course it all goes to shit when you accelerate fast and run over 60 miles an hour! You have to baby it to get 38 miles to the gallon sometimes 40 , with that 5 gallon tank I can go 200 miles before I hit Reserve most of the time! LOL
@@SaddleTrampTV also if you have a higher lift cam on stock Harley lifters they will fail at or around 50,000 miles! I'm speaking from experience just went through that! Broke a lifter, lifter block, went back with fueling lifters S&S adjustable pushrods and while I was in there I changed out the Breather valve that runs off the cam and replaced it with S&S Reed breather!
@@james44mag31 It has a 165 main. But I'm now running a CV again with a 48 idle with a 185 main. Rode this on a 1400 plus round trip and it did a whole lot better. Check out my later videos on this matter.
tall cable bracket is XL and lower bracket is Big Twins.
Good to know. Thanks.
I subscribed when you were explaining “ I have these parts and I don’t know where they came from” , good channel. Good presentation, great topic.
Before you burn up your motor research how CV carbs work. They DO NOT adjust themselves with altitude. You DO have to rejet for altitude. Shit I even run separate jets for summer and winter on my CV's
That is a flatslides I'm not surprised, it should be a VM roundslide
I had my Mikuni HSR42 as lean as you can possibly get it (17.5 pilot, -98 needle, 50 squirt, 165 main) yet 36-38 mpg was the best it got fuel economy wise. I went back to the Keihin and am looking at achieving 50 again. I'm all about fuel economy since I ride with guys that have 6 gallon tanks. My bike is 100% stock and even has the stock cam, mufflers and airbox.
I am still running a Bendix on my 72 FLH with the factory wire throttle cable through the handle bars. It works great on the Shovel but mileage is not good. The 02 FLSTC has a CV carburetor I had issues with at first due to incorrect jets. My 01 Road King is fuel injected and I don't know anything about it yet. I think I am selling it and maybe the 02 FLSTC too so I can buy a Evo that I can work on. Did you check the after market chrome cap on the one carburetor for air leaks. I have seen where the rubber gasket gets pinched and you lose suction.
It's good.
I'm a mikuni carb guy, I have one on all three of my bikes. A Dyna, Heritage and Roadking. When tuned they're by far the best.
Great score on the bike... I have a 94 FLSTF (Fatboy).. I bought new in 94 and refuse to go fuel injection. I, like you do most of my work on my bike a,d want to keep it that way. Great videos brutha..
Where are u located?
South MS
Sounds nice! The Mikuni on mine is a 38 VM. I get real good gas mileage with it. Course it is on a Shovelhead.
That's a evo engine harleys best engine ever
Emmitt Till ...Long live the EVO and they will!!
Love my Evo. I had that sound on my 98 MMI; positioning sensor went. PERSONALLY, I wasn't comfortable with it. Back up to an even factory spec. 1k is kinda high now. I'm happy at 850...my sweet spot. It'll be there when I go Mikuni 42
You make some interesting video's. Thanks for posting!
I agree... I just want to cruise :-)
The Mikuni is set up wrong. Either the pilot is to big or the accelorator pump nozzle is to big. It should give you that 40-45 mpg. That's what I'm getting on a 96" evo with a 42mm Mikuni.
I later found out the it was that the motor was hopped up a bit. I talk about that in one of my later videos.
Yea, I did that same dance with my 88 FXR when I figured out the problem with it, bad intake, had tiny itty bitty nick in the intake mount point to the head.
If it ain't broke, ........ Break it!
Well done done very handy.
Love my evo, stock with pipes and s&s airfilter, done!
Ride safe man...
It's probaly me! Always happens to me aswell.
I've got 2 mukunis, one new the other needs a rebuild. I like the throttle response, but yeah gas goes fast!
Channel keeps getting better. Keep at it, brother!
99% of the people dump a c.v. for a mikuni .. want better gas work on jets ..simple as that
Rather have a super e
Had a couple of CV carbs and they consistently stalled and caused problems.
Been running s&s carbs on everything for years.....easy to work on..easy to tune....
I remember when a friend of mine bought one of those mikuni carburetors for his 93 dresser and he also was not happy with the mileage. I'll stick with my CV carburetor it does okay. So many people I know they talk up the SNS or the mikuni. I had an SMS years ago this was before they had an accelerator pump I never got used to that. I had an SU and if I knew more about it I probably could have made it work well but I can make a CV work good
I have found that using a Sportster needle one that was used in a CV carburetor prior to 1988 I think that's the part number year. As it has a very narrow taper throughout the shaft gives real good mid-range acceleration. This is the first time I heard you talk about Keenan. As I watch his channel also I picked up a lot of good pointers on how to set up a shop and also work on bikes through him and his videos.
It's surprising that a carburetor could make a motor vibrate more but.
I just bought a new Mikuni for my FXR , its got an S N S now that has issues ,so I bought that same carb ur about to switch ... But I live in the SF bay area , my bike is a club bike ... I don't mind if its very fast ... Ive got a hotter cam ,and thunder header , Im hoping my problem is the carb ... It won't idle at a stop sign but runs good at higher speeds ...
Oh, and try Drag Specialties 25w60 oil! My 88 EVO has over 170,000 miles on it using that shit...Evos don't care much for straight-weight oils...get rid of those Dunlop tires...ride like a BRICK!
Job well done! Unfortunately I haven’t had any experience with a CV carb. Both my 1999 Indian Chief and my 1996 Heritage (with Fatboy fenders) have S&S Super E shorty carbs on them. Wonder what the difference would be...
I have a 1982 Yamaha Virago 750 and I converted it to use that same carb. Works like a charm.
The CV-40 that comes stock on The KLR 650 comes on some Harley's it's 100% reliable and easy to jet properly they wouldn't use them if they didn't work nicely a rebuild kit is like 12-17$ being cheap to maintain.
These carbs get clogged up and fail so often and cause everybody a world of grief, I wish I could just change everything I have to fuel injectors and a fuel map. I don't know why we are still using 1880's technology in 2024.
I am currently running a CV on my 93 FXDL...pulled it off a couple of months ago and cleaned, then re-jetted to a 45/180 and trimmed the slide spring a loop (also a Head Quarters Rumble Stick camshaft)...did a 700 mile trip a few weeks ago, straight through ride at 70-80 mph most of the way....I figure I am getting around 45 mpg if I can keep from twisting the throttle open further.
Did the previous owner swap out the cam? Changing the carb and ignition hints he might have been on the performance road and a cam may have been done or was about to be done. I went down that road with the Superglide but I bored and stroked it to 96 CUI, did Manly valves, Crane springs, Andrews cam, S&S Supercarb, dual points and Acell super coil along with having the heads ported, flowed, and polished by Branch. It sure did run.
Mikuni vs s&s super e?
I have a 92 softail with over 80000 miles smokes a bit but still runs like brand new!! EFFE!!😁
Love the channel! Totally agree with you about newer bikes. I wrench a bit as I have an 1980 Shovelhead that needs care and feeding to keep it happy. But I wouldnt get rid of her for anything! The EVO is, in my humble opinion, the best motor they've made thus far. Has that great sound, like my shovel, which to me sounds like the beat of horses hooves. I have a Twinkie Road King for when me and the wife ride 2 up, but she has her own bike too and its a Shovelhead! Love your atitude about riding. I'm no longer a member of the "go fast" crowd either since I became "re-citizenized" a couple years back LOL. We love the 2 laners and back roads. You discover so much more on them than just blasting down the interstate. BTW I've got an S&S Super E on my Shovel and it works great. It's a really old one, but I have found it to be really easy to adjust and maintain. Looking forward to your future vids!
Big mistake changing that to a C V CARB ... I WAS NEVERY HAPPY WITH THE CV CARBS = COUGHING = NOT FOR A MINUTE WOULD I EVER GO BACK....
the mikuni is the best thing you can do to a harley. when swapping my sporty to a mikuni and dyno tuning i picked up 8 horsepower and 5 or 6 MPG
My bike has a mikuni I'm going to switch back to a super e
Me and my brothers built my little brothers bike we used a callaghers hot rod baby g frame ran a twelve hundred bored thirty over with Buell heads and started with Andrews n89b cams and mikuni carb it was uncontrollable couldn't get it to idle switched to a super e no problem since
Jeremy Steckman ship me that mikuni
Sorry guy the guy who built the heads on my bike has first dibs considering he's my son
Daniel Pyle I wholeheartedly agree. Unless his Mikuni had ethanol damage I can’t imagine there being more vibration from the bike, unless the vacuum plug or the boot on the VOES line was cracked, or the VOES needing to be tuned to the different vacuum signal. ? Never had a Mikuni carb cause vibration, and out of my thousands of fellow riders most of them running Mikiunis, they refuse to part with them, I know Ive tried to give them S&S Super E’s with manifold & seals plus cash, and buy lunch, (i was in a hurry to gat the bike going and didn’t want to wait for the new carb to ship, being that I had another project that needed a Mikuni
Thanks for the info I have a 1995 Dyna Screamin Eagle stage 3 of course clubbed out. I'm gonna switch over to the mkuni and I was wondering about the cables. Thanks again. Like the videos keep up the good work. Please check out backroadbiker adventures on TH-cam Chuck puts out some awesome scooter trash videos. I have some videos of my bike up to have a great day boss.👍✌🇺🇸😎
Love the dance,shows just how much you really enjoy the music, never have had a Harley,but can see the love,& pleasures of working on them especially when it seems to hit perfectly, been in automotive all my life but it’s kind of the same as when you put a nice cam , a good carb & headers on a old Chevy,& it bumps so good I can get the same dance !!! Been looking for a Harley & you’re videos are helping me decide what to look for,thanks & later.
One of mine is Honda Shadow Ace 1100 i love these bikes styles
I used to have one of those years ago. That's a good bike. Very solid.
@@SaddleTrampTV i subscribed and dropped a like on few of your vids.. any tips on the shadow? Already learned the connector for the stator can burn up.. well thanks sir
@@natesilva3232 I never really had much trouble with mine. I know it's a booger to replace a broken shifter shaft, so be careful how hard you shift. I replaced the fork seals in it before, but the front end is made by the same company that harley get's theirs from. So they're all pretty much the same.
That is the trouble i AM having with a 1984 FXR, carb Mikuni A gives black spark plugs, changed to a carb Mikuni B, the engine hoy worse, lots of black fumes from the pipes....! NOT HAPPY AT ALL as i thought that changing the carb A to carb B would solve the problem.. mmmhh damned...! Any clue on this..? Please help... Changed the manifold gaskets already...black smoke and engine NOT STEADY AT ALL..!
since I just got the same bike as well ... I have a feeling I will learn a lot from you ... thank you man! great video! ... I know what you mean man ... you want a smooth ride and a good smooth ride and not a freakster dragger ride... same here bud ... thank you for this video ... kind of funny too.
I know what you mean about the right potatoe potatoe rhythm . When my harleys are runnin right I also do a rock type dance movement. The base drum beat. The latest 97 fatboy I purchased 8 days ago didnt have the right beat, until I timed it at the nose cone and turned that module to the left which retarded the engine down slightly. So that fatboy evo isnt timed by any scanner or lught but I know at age 64 and tons of experience when the BEAT is right and is followed by a non hesitating throttle rev . Then when I get that If there is no black smoke out of my drag pipes then I KNOW ITS RIGHT. In my collection of movies the top movie is Billie made in 1965 with patty duke in where she becomes the champ in the HS track team and she would always say You have to have the BEAT. Your harley and my fatboy are the style I will ride for life. I listened to that engine as you rode your bike on the highway and know its RIGHT and the right harley to own. It will last you for as long as you live because it will never go out of style and everything is totally rebuildable.
Question.ive considered an Lectron. Which is.basically a body with 1 jet. Heard all kinds of ideas like"impossible to tune to simplicity is best". Any thoughts? Thanks.I have a 71'BSA 650 A65L AND A 2002 DYNA 88. BOTH SINGLE CARB .THANKS.ONE PUNCH GEORGE.
Great commentary....your a knowledgeable Harley guy one can fall back on for repair help....vids...bring em on!
ST I I fully agree . I have 2003 XLH 1200 Anniversary ,it has a CV and I rejeted with 6sigma and my friend has a 2001 XL 1200C with 42 Mikuni and open pipes on a 54 mile run he used twice the gas I did .. and now he is facing some costly repairs . and I am still running smooth , so I am running stage 1 and he is running the stock custom with Mikuni , so I agree its easy to over carburet the stock motor .. once you cross the line you loose more then you gain .. great video dude ...
You have enough CV carbs to make one good. = BOAT ANCHOR 3 = will USUALLY DO IF YOUR BOAT ISNT TO BIG....
S&S sucks gas, Mikuni carbs are the hd factory screaming eagle units, if you’re getting bad mpg (I get-/+ 55-60 with a big cam) You need to jet the carb accordingly (I know what happened) read next comment
You and I think alike on this.
I responded on your video about the trade giving you a thumbs up.
I have a '97 Heritage that I really like after riding an Ironhead Sportster for a long time.
I took a trip over the Sierras and back to Nevada and got 50.3 mi per gal with a cv carb on the Heritage.
I pretty much want to stick with reliability for longer trips as oppose to more power, ...for better gas mileage. I live at elevation 4750 and run a 45 pilot jet and 175 main, that and the rest of a stage 1 -(different air and exhaust).
Are you anywhere near by? Always looking for people to ride with.
I'm about 15 mi south of Carson City, Nevada.
This is a cool video to take ideas from, I'm thinking the 2 washers to raise the needle will improve performance but rob gas mileage.
th-cam.com/video/iTPPP8jkje4/w-d-xo.html
Keep it between the ditches.
The Mikuni hsr42 is not tuned right . I get over 50 mpg all day on a 98Flsts and my93 fxsts with a Mikuni . That includes a 1600 mile ride .
Both bikes have a stage 3 builds .
If tuned correctly the HSR 42 gets the same if not better gas mileage than the CV carbs. Only downside is the HSR makes you want to twist grip more... then you get about 30mpg. The HSR is a much much better carb if you ask me.
I’m new here today, and will sub right up. How did it end up on mileage for you in comparison?
At each fill up, I would divide the number of miles by the amount of gas that would top it off. For example... 50 miles divided by 2.5 gallons would be 20 mpg. Try it.
Oh I do that very tank. My sending unit is bad and HD keeps putting it on backorder, so that’s how I know when to fill up. Just curious if the carb gained you mileage over the Mikuni.
A lot of times that "potato potato" at idle is because your VOE (vacuum operated electronic) switch is either not connected (electrical wire to module) or vacuum line to carb not connected. The "potato" idle on an EVO indicates retarded timing...oh shit...I just saw your next video...😂
i have a question regarding the bandana trick. i don't have a front fender and i realised once i went over water that it wasn't attached lol. how good does that bandana trick work as far as cutting down rooster tail from coming up to your face?
Well I'm a new subscriber to your channel and I really enjoy your videos and I have a question for you. I am thinking of converting my 98 road king efi to carb and after so much research I'm so confused on what carb to use and my 80 inch evo is completely stock so could you give me your opinion and I'm like you I just want to ride and not race so any help would be appreciated.
Thanks brother !
the CARB sucks gas???? That's a new one!!! Carbs basically do what the engine needs them to do...sounds more initial set up failure to me. Or maybe just the carb rejecting its new engine much like an organ does with a human body when the organ knows the human body isn't worthy...
I got a 93 Fatboy I get 44 to 52 mpg with my Mikuni They are hard to tuned But once tuned U can't beat them My cv i never could get over 38 mpg Most of time it was 24 to 30 mpg
I' just replaced my CV on my '96 evo. I like this carb. I adv 44mph
You know, I do that also, a long while back though I realized I was not going to stop doing what I do. LOl collecting parts and buying broke stuff and fixing stuff and all that. So I started doing this, i keep a fat roll of Masking tape and a sharpie. Only takes a second. i just mark what the part is and wrap it on the part , say a cable, I make a tab, on a carb I find a clean spot and tack it on Or use a toe tag . Im telling ya man, Im just 53 but I cant tall ya how many times I have picked up a part and thank 28 year old me for making those tags. LOL it;s like using a cheat sheet also, like back in high school. You spend all that time writing little notes to yourself on your arm or a small paper or whatever and when you are taking the test you find you accidentally remembered that shit! LOL
Hope this helps someone else some how.
My mikuni ate the gas big time on a fatboy. Never could find balance with . Went with S&S carb and breather, got it set pretty perfect and never looked back
nah bro, if you're a gas hog, nothing a float adjustment, jetting, and general fine tuning can't fix. I tuned a cheap $40 chinese clone, runs well, easy on gas. You can do it too :)
Hi, still watchin' I bored a 450 honda 100 over, Put a set of 58mm miki's on it. for a small bike it hauled some ass.
Besides the issue with the cables, did the CV carb bolt directly on to the bike without any other adapters? As to the cables, how many does the Mikuni have, two or one? What about the CV? Thx.
Thunder in the back ground, now some thunder in the foreground!
Question: My question isn't about a Harley, it's about a Mikuni 42A20 pumper carb 28mm, oem on a 1987 Suzuki DR200 dirtbike. Bought it because I had one when was a youngster and always wanted another. Carburetor was apart in bag, missing a couple jets and hole drilled in bowl! I think plunger had gotten stuck on accelerator pump so they driĺled hole and knocked it out? Had a BUNCH tell me I had to put a 42A20 or 42A21 pumper carb on it, that the low priced cv carbs online would not perform well enough to enjoy trail riding? What do you think, or possibly know about this? Thanks. Oh, that's one nice Harley!!
I'm not really sure. I pretty much do CV's and occasionally S&S. Being that I already have the parts for CV's and know those pretty well, that's the main reason I didn't go with the Mikuni. I do know that with a Mikuni, when dialed in right, will certainly out perform any bike with a CV.
one of your video's just came up so I watched it. It was your newest one & I liked it very much, very interesting!! I then went back to the video where you made the trade. I enjoyed that and have watched the others, forward to the newest. I subscribed to your channel and look forward to all your video's! I own a 2005 Ultra Classic & although it does have the fuel injection ect., I still feel the same as you do regarding prefering the older bikes over the new or newer. I hope to, as you, to learn as much as I can so I can do at least the basic repairs or more if possible. Thanks for the inspiration! Enjoy...
Thanks so much.
Oh how I like that potato potato potato sound the older bikes give ya, miss my 80 FLT.
