1982 Gs650E Runaway Throttle at Idle

[EmmCee]

Alright, ive been over this motor with a fine toothed comb. I cant find anywhere that air would be getting in so im at a loss.

I can get it to idle just fine, but the moment I blip the throttle, it runs away and redlines and I have to hit the kill switch.

But when it happens when im riding, I can stuff my hand in the no-no square and fiddle with the idle speed screw and it'll drop down.

Any ideas short of "*@%^$*@%^$*@%^$*@%^$ can it" will be considered.

Disconnect throttle cable at carbs
test by actuating throttle at carb thus removing cable etc. from being a factor.

Yup. Did that already. Cable snag has been ruled out.

Ah yes, ive read through your list many times. The only things on there that I could see being the culprit would be the pod air filters, but im using good K&Ns that I modified for clearance for air passage. Unfortunately this bike was in very very bad disrepair when I resurrected it and the airbox was little more than paint and wishful thinking holding the rust together and the same went for the exhaust. But the pipes I made for it (if my math was correct when making the baffles) should have the same backpressure as the stock exhaust.

Admittedly though, the carbs are still using stock jets.

Update: Found the leak. And it's embarassing..

Forgot to tighten down the intake boots all the way last time i pulled the carbs. At least i know now

So future GS owners that happen to find this thread. Dont be like me. Tripple check your work

The bike won't run well with pods and the stock jetting. It will run hot, among other things.

Stock jets with pods???? Hard to imagine
