Kawasaki Vulcan 800 ~Top Side Carburetor Performance Mods (VN800B/C/A/Classic/Drifter)

[@mistreku]

For the ppl complaining about the fingernails, are you here for the tech part or to get fingered? The man's a mechanic (even if a home mechanic), not a baker! Also, this is YT, you can always skip forward if the drilling part takes too long (what I did, no need to see how to drill a hole in real time, I believe it's not rocket science). I swear, some ppl just love complaining about everything.

[@CruiserDayz]

Thanks! This was an early video, just trying to get it out there.

[@Bike2freedom]

Well said mistreku!! For real, the things some people find necessary to complain about astonish me. Thanks for the video CruiserDayz and let the haters hate and the rest of us have some fun!

[@tylerwatt12]

Shims don't do anything if they're put on top of the c-clip. Shims are meant to go on the bottom to raise the needle and allow more fuel through.

[@shawndaniels2846]

Shims on top of the needle are by instruction from the manufacturer. The only reason to use one below is to raise the needle 1/2 step between the adjustments.

[@Taffoman]

As a professional steel worker I am slightly amused with your drilling. I can recommend using upright drill and some cooling agent so the drill bit won't heat up and then get dull. Othervice pretty interesting. you could have shortend the drilling part with the video editing.

[@CruiserDayz]

Yeah I know.... It is a bit embarrassing. All of my 1/8" drill bits were shot. Had a lot of videos to upload and spent my time editing the others. I figured a shitty video was better than none at all.

[@redshift6712]

@@CruiserDayz It's a "bit" embarrassing! Pun intended? lol

[@MrTravlinman1973]

I would have drilled a 2nd hole beside the original hole instead of making the hole bigger. That way it is reversible . If you have any issues you can fill the 2nd hole with rtv silicone and back to original..

[@MAD1450]

Word has it he's still drilling

[@ChrisTaylor-gm8pt]

So does this affect idle throttles response? What does it change?

[@arvidgrant9346]

Fantastic videos ... All of em ... Have one question though... Why drill out the hole ... What's the benifit... Thanks

[@terrysahnow9978]

Arvid Grant I agree - why would I want to drill this out?

[@CruiserDayz]

Arvid Grant The Hole allows better air flow to optimize the actuation of the diaphragm. Something the guys on the forums have been doing to make things better.

CruiserDayz can you link the forums page for me .. I love to read up on my bike .. always learning.. thank you again ... excellent videos

[@robertprice7246]

What does enlarging that air hole do for the bike exactly ? Looks like maybe increase the throttle response?

[@francisguchie1973]

Thanks for the video and the comments.. Do you have any lower side tuning tips like this?

[@justinsepeda9049]

Good video and very informative. I have a 1998 Vulcan 800A and I'm curious as to what intake/carb work you'd recommend if I cut the mufflers off the factory pipes and just run the straights?

[@TrailerDayz]

An adjustable needle valve kit would be good. New jets also. If you have a bike shop around call then up. They can get you the parts cheap or do it for you.

[@mymusicaccount1456]

Next thing you do to bring the bike alive, punch the baffles out of the exhaust (I'm going to assume that since the carb has an aftermarket needle that it's already been fitted with a jet kit)

[@soundspoon]

man i took the baffles out of my vulcan... this thing is loud as shit, i love it

[@Randall-y5b]

Is your drill in reverse?

[@maurizio-]

What is the correct size of the drill???

[@kopynd1]

could you explain to me would it matter what side the wires conect to the coils as there is no discriptoin on the coil body or the wiring diagram, cheers

[@joekemper6094]

any tricks to replacing the intake gaskets? i have a major leak. any suggestions?

Sounds like the fuel tap, start with a repair kit!!!

[@robertangelo6479]

Im confused so i installed the v&h pipes on my vn800, i plan on doing the grampsizing mod on the air box, is rejetting still nessasary or does this process take care of that ?

[@CruiserDayz]

You don't have to, but you should.

[@willsrestorations]

I DON'T KNOW HOW TO MAKE ANY SENSE OUT OF THE ANSWER THIS GUY JUST GAVE YOU BUT YOU ABSOLUTELY MUST REJECT THE CARBURETOR WITH V&H REBUILD KIT

[@Dimca75]

What is the diameter of the drill hole? Is this hole enough or more?

[@Gagibit]

Most Keihin have 2.8mm and the mod drilling is up to 3.0mm

[@imrealzombie1]

hi. help me please. my kawasaki vn 800 drop a lot gasoline by the two littles holes down of the carbu. what happen to my kawa?

[@ErikISkogen]

your floter is stuck

[@JohnDoe-pu8ei]

Fabian float needle

[@nicklausmisiti5204]

This has happened to me twice this year. As others said the float needle is stuck. Put an aftermarket fuel filter in and use high octane gas. At least this is what I'm trying. Otherwise I'll have to break down the carb every couple months.

[@rickythornton8649]

My 2000 1500cc was doing this, both pilot and main jet we're stopped up.

[@shanedebarra4986]

Safest ... drilling ... ever 🤔🤣🤣🤣

[@leadfoot1892]

Silicone and gasoline cause aluminum to corrode and pit. Discovered this with a bike someone used silicone for floatbowl gaskets.

[@brentmack51]

leadfoot1892 nonsense ethanol gas is what makes aluminum corrode and Pitt

[@codypalmer2732]

So how do you know you don't need to retune your carb after this?

[@rayhogue7948]

This only improve the speed at with the needle response to throttle. I've done this years ago and I never had problems. The bike is now so much more responsive.

[@skulledmonte84]

you didn't cut any coils off the spring ??? was on the forums an that helps too
