Idles really high

[Isaac_62]

Hey guys,

 

Well i just finished with a rebuild. Just started the bike up and it seems to idle really high. I have tors removed. i just got through syncing the carbs. I have v force 3 rreds and the stock carb setup. I dont think i have a leak of air somewhere but i cant figure out why im idling so high. The idle screws are all the way out,the choke tube is between the carbs and its still idling really high. could it be that my pilot jet being too big has something to do with it? could it be i have a leak around the crank seals which are brand new? could it be a base gasket leak? there is no play in my throttle after i synced the carbs, could it be the slides are not all the way down? what do you guys think? I just cant figure this out... All help is appreciated.

 

Thanks,

sounds like ur slides aint going all the way down i would readjust them

Yeah you say your slides are all the way down but it wouldn't cause it to idle high. If they were all the way down it wouldn't idle at all you would have to keep your thumb on the throttle to idle it manuel IMO. Check the carbs out and the slides sounds like a slide is stuck it happened to me when i took my carbs apart for the first time (damn that was a long time ago) The idle screws have nothing to do with it if there all the way out....Just another reason why my theory is correct.

When I remove the TORS and drill/tap for the idle screws, I always hold them up, SLOWLY turn the idle screw in until it makes contact.

 

Then I turn it in exactly 1.5 turns in. That's normally pretty damn close.

I use the Sync Tool from FAST racing to tune idle from there. But that will get you close.

 

Don't rule out the possibility of an air leak...

OK...just reread that. You should have a little slack...

Also...when you tightened the carb caps...did you tighten them down tight, or just hand snug them?

 

Those carb caps are very sensitive. Loosen them back up, hand snug them down, then use the L shaped hold down bracket to keep them from coming loose.

 

High idle is usually caused by throttle malfunction or improper cable/routing, or...being lean...or having an air leak.

Huge pilots if anything will richen it way up and make it boggy, like you pulled the choke on.
