HELP bike will not run right
07/05/17 at 21:08:54

hello i have a 1986 suzuki savage ls650 i cleaned the carb as soon as i got it and i got it to run but it wants to stall as soon as i give it a quarter of a turn on the throttle it will spit and backfire once or twice then just quit ive cleaned the carb about 5 times now i got good spark my question is how does the pet thingy work i see it has a vacum line im geussing its just like a feul pump but without the bike running with the petcock open somtimes it dribbles out feul and other times nothing at all is this normal because the bike isnt running or should feul be poring out of it? any help on this would be appreciated thanks. Undecided

You could turn the petcock to the prime position and see if it runs better. If it does, the petcock could be the problem and should be replaced by a Yamahas 660 Raptor manual petcock. If you do this you must plug the vacuum line.

Absolutely, just buy the real petcock or you will heave this issue again. Takes all of 5min to install.

Re: HELP bike will not run right Reply #11 - 07/06/17 at 19:46:06 Just get a piece of clear tubing and slip it on the drain of the bowl, hold it up by the bowl, see where the fuel level is. Up to but not above the gasket.

You set the float height by taking off the float bowl ,turning the carb upside down an carefully bending the little tab that the float valve hangs from until the highest part of the rounded float ,measured from the flange,where the bowl and the carb body meet(without the gasket present) is 26.4 to 29.4mm or 1.04 to1.16inches.You can check it with a clear piece of hose as suggested by JOG-2 above.But you should really change your petcock first.
