High idle

[les]

I just put new carb boots on my bike because the old one where cracked and beat up and now i get a hight idle when i rev it up, but if i slow the motor down using the clutch like stalling it out it will come back down to normal.. thought maybe i had a boot leaking but i took them all off and put sealant in them and tighten them back down and still have the problem. think i need to re sinc my carbs? any help would be awesome!

I know you dont want to hear this,but it really does sound like a vacuum leak

Have you adjusted the idle screw properly? Mine was doing that and that was all it ended up being, is it making your pipes run red hot after a while of running?

[les]

I have tried spraying me boots with carb cleaner to see if i get a rev and get nothing... any other spots i can check for a leak?

[shinyribs]

Not that I know of. Thats good news,though. Might wanna try Hellbilly's recommendation then. He knows everything!

[les]

i have adjusted it to where it will just about die when it idles down. no the pipes don't get red hot.

[shinyribs]

And this is a DOHC with CV carbs,right? Just checking to make sure we're on the same page.

[les]

it also will bog, loose power, pretty much kill its self at high rev around 6500,7000

[les]

yes sir

What year bike is it? I had to let the bike totally warm up for probably about 10 mins, every so often it would rev right up on its own, then I would idle it down again, until it stayed where it was supposed to after revving it up. I just know I went through the timing and checked all the cables and couldnt figure it out, then my dad messed with the idle screw like i described and it was perfectly fine.
I wish I knew everything Shiny, not sure if your being nice or just giving me shit, lol

its a 79 cb750k, it wont rev up on its own just when i give it throttle it dont want to come back down from 3,4000 unless im at a stop and use the clutch and bog it down

[les]

I kept lowering my idle down and and advanced my timing all the way so it would no die and i think it might have worked. cant really rev up to much I have 4-1 megaphone exhaust with no baffle and im sure people dont want to hear it rattle the windows at 9 0cloock at night. THANKS FOR ALL THE HELP REALLY APPRECIATE IT!!

Cool, glad you got it working, although I am not quite sure how far you advanced the ignition or if it's a good thing to do, maybe it was just totally out of whack to begin with? I had the bolts that attach the starter gear to the shaft come loose on their own before, so it could be possible the ignition was retarded or got retarded, have you tried timing it in according to the fsm?

[les]

ya those bolts where lose before. it had a knock and couldnt figure it out thought it was my slack ajuster and took my timing cover off and seen they where loose and had been for some time. not sure if that would effect it??? still dont seam right though.

The first. I dont do the second...unless you ask for it

[Hellbilly429]

I don't think it really affected anything other than make noise on mine, am just wondering if maybe somehow your timing got thrown out of whack. it's pretty simple to time these in without a gun, but damn are they picky if you aren't relatively perfect on the timing.

Wasn't sure Shiny, was like shit, must be I said something to offend him so now he's bustin my balls hard!

[shinyribs]

Nah man, we're cool.

how would a guy do it with out a light? a nother question, just put a new alternater rotter in the other on fried on me after i took off the farring and put a head light on and now it will not charge the battery. dont know the name of the points that rub on the rotter but the holder is cracked and one is sticking so im thinking it is that but my head light wires will have 12 volts untill i put them to the light and it will drog to .5 volts. would that mean the regulator you think? driving me little nuts!
