[@joebonner3499]

this was an awesome run through!! I love how effortlessly you did this rebuild. I'd like to see you do a video on how to tune a carb.

[@kruesioriginals]

I might do that when I put my FXDX back together I’m gonna have to tune it going to be a while though I’m on the hurt list

[@jakejuett6390]

@@kruesioriginalsPlease do this! Would be greatly appreciated, can’t seem to find any tuning videos with the full CVP mod installed.

[@JohnSmith-de2mz]

@@kruesioriginals I just installed the accelerator pump nozzel. In the instructions from CV Performance you aim the squirter at the notch at the back of the float bowl which I did. Doing that the spray goes by the right side of the needle you say to aim at. It runs good but if it atomizes better hitting the needle I'd like to twist it to hit the needle. Since you've done a few what do you thunk, will it make any difference? My bike is an 03, 95 inch, Mondello heads and Wood Tg8 Cams and Dynatek ign and Dark horse crank. It screams but always looking for the advantage. Thanks for an answer.

[@MrWootastic]

Would love to see a vid from you guys on proper tuning of these carbs! Keep up the good shit gents. Love it all 🤙🏼

[@tommys2979]

Bring bike upto temp. Set idle speed then turn the air fuel screw in until it stumbles then back out until its running good and add like an 8th of a turn should be good to go. These carbs are really simple.

[@SleezyRider883]

i mean he aint wrong with 99% of the shit he says. Just disagree with that carb cleaner but thats one of those things im just gonna have to learn the hard lesson myself.

[@masterofnonetv8361]

The difference in carb clean and brake cleaner is brake clean has methanol to help it evaporate faster but it can damage rubber seals, so he has it backwards, brake clean is more aggressive due to the addition of methanol.

[@jamesrobinson2433]

By far the best breakdown on rebuilding the CV.

Thanks!! Great video.i have a question about the high flow fuel inlet.how much bigger is it do you know?.I bought one, haven't put it on yet but id like specs if you got them and what else should I do to compliment the high flow inlet... anything??.... thanks in advance

[@kruesioriginals]

I don’t really know what you’re talking about. There is no high flow inlet except for where the fuel line hooks up to the carburetor. That will not make any difference on how the bike runs, though no matter what you’re gonna have to tune the carburetor if you put this kit in.

[@ronadamson4595]

Yost sells a "high flow"brass replacement fuel inlet for the cv carb.i was just wondering what the inner diameter is for the "higher flow"

[@Chancho66]

stock 1/4" High Volume 5/16 this video, especially the 3 monkeys removing the fuel inlet valve, is quite comical... red loctite in a carb? don't use carb cleaner to clean a carb? use brake clean? maybe use a Tap to cut threads NOT a set screw...read another magazine.LMFAO

Thank you new gimbal in the house

[@brentphillips262]

03 Sportster 1200 custom. I got the "imultion" tube to squirt when o jad the float bowl off but it won't do it when i put it back on. Chanfed the spring and fuel diaphragm and little o ring on there. Any idea? Whole project was to up the low jet from the 42 in it to a 45 to get rid if the CV carn spit/cough off idle and air fuel screw with an adjustable. Im mechanical and this seemed simpe but she wont squirt. Knew that was a myth. Lol. Seriously though. Hope you see this. Was following this video step by step to do the parts i wanted to. Bike ran like a champ untl i touched it. Wont start. Has fuel.

[@goatkiller91]

In your opinion is a fuel injected bike better for wheelies/burnouts than a carburateued? Or does it really matter?

[@jaredkish992]

Can I ask you a question from your experience… I have a 2000 1200s (bigger stock cams than the other XL and has dual plugs ) the stock main jet is 195 and I believe the stock is 42 (from what I’ve read online?) but I have added a louvered air box with performance filter and a two for one exhaust twin power performance coil pack and some other light mods. I’m thinking the main is fine at 195 but I’m feeling like I should bump the idle to 45 or 48 since she’s running rich with a 42 or if you think 42 is the go to spot still. I’m about to do this exact kit. Lmk what’s worked best for you! Great video man 🤙🏼

[@kruesioriginals]

That’s not how tuning works, you either have to put it on a Dyno or ride it and test it and move the Jets around till you get the best result for the altitude air density and set up you have

Does a vapor locking issue cause the CV carb fart? Ha

[@jongass7799]

I recently pulled apart my stock cv carb from my 98 dyna wide glide 80 cubic inch I removed the accelerator jet and was told it should have a needle or ball and spring under it it was also pressed in like the one you removed so I ordered a replacement similar to the one you just installed but the one I ordered came with a ball and spring my question is should the stock on have had anything under it or is it necessary to have a needle or ball and spring under it will it function normally with or without out I can not Find much information online about this trying to figure it out before I install it back on the bike

[@randylanhart1387]

Nice video. Ryan here's a feature on the 2001 Buell M2 CYCLONE EVO SPORTSTER MOTOR . That Eric Buell put on those bikes . what it is is a external idle adjustment feature..it should fit on any 40 mm cv carb. If I'm correct!! And I have been wrong at times so check it out. This little gizmo screws into the back of the carb .it features approximately a 10" cable mounted knob that after routing sticks out past the frame and gas tank.. making quick and easy idle changes effortless on the fly. I love mine. Also you can use it on cold starts to help your bike warm up faster, using less time on choke mode!! .I THINK EVERY CV EQUIPPED HARLEY THAT CAN USE IT SHOULD HAVE IT INSTALLED??? IM FUCKING VERY SERIOUS ON THAT POINT!!! LOOK UP THE BUELL CV CARB. I'm not sure how many were installed but ifin you can do it..DO IT.. NOW IF I COULD FIND A FUEL ADJUSTMENT SCREW JUST LIKE IT, IMAGINE THE POSSIBILITY OF JUST REACHING DOWN AND TWISTING . INSTEAD OF LAYING ON YOUR BACK TO FIND THE Fuel SCREW.OR RIPPING THE CARB OFF TOO FIND IT.OR BURNING YOUR HAND ON HOT MOTOR.

[@joshua-xn7wt]

Excellent video thank you

[@kruesioriginals]

Glad you enjoyed it

[@Zerk_Ziegler]

Keep in mind that before the mod, the float bowl vented into the air cleaner, and after the mod it vents directly to atmosphere. Since the pressure in the air cleaner is less than atmospheric, the bike will run a bit richer on all circuits as a result of the mod (because there is now a little extra "push", provided by the atmospheric pressure, to get the fuel from the float bowl and through the jets, in addition to the big "pull" of the vacuum in the venturi and the intake manifold).

[@jaredkish992]

Hey man pro tip if you have the time of course. If it’s anything brass or metal like the accelerator tube put it in the freezer for 24 hours and a little dielectric grease she slides in like a morning f…

If you changed the float level from .413 to .400 you RAISED the fuel level in the bowl, opposite of what was explained in the video.

Wrong, you got it backwards

[@Zerk_Ziegler]

@@kruesioriginals Did he? When float height is increased, the float valve will shut the flow of gasoline into the float bowl earlier and vice versa. Float height and fuel level are, in a sense, inverses of each other.

I wouldn't advise using a Phillips screwdriver. The stock screws are not made for a Phillips head, and the heads will strip easily.if a Phillips head is used. They need a JIS head screwdriver. JIS looks similar to a Phillips but fits those screws so it won't easily strip the head.
