GL1100 Slow to Return to Idle

Postby pappajim0719 » Fri Dec 05, 2014 12:55 pm



Hello, as the subject says, my 80 is slow to return to idle. I cleaned the carbs, sync'ed them, but it's still doing it. On decelleration from 3000 it will drop to 2000, then slowly return to 1000rpm. The slides are all working properly, is this the fault of the air cut-off valve?

Sticky cable? lube it, return spring not installed correctly? change it, slide issues? polish and clean , vacuum leak? find it unlit propane torch works or starter fluid spray can???, doubt it's the air cutoff unless it's leaking air into the system.

Good suggestions, but all that is working, has been cleaned, lubed, etc. I'm going to explore binding linkage next, it seems I read somewhere if the carbs were bolted together incorrectly the butterfly linkage could bind up,

does the throttle SNAP back into place and does the bell housing seat completely when it does?

The throttle backs off, but I wouldn't say it "snaps", and I don't know what you mean by the bell housing

it's the big spring and "wheel" that the cables attach to on the carbs. Your throttle grip should snap back when you let go of it..if not a cable is bending or bell housing/linkage is not right.

Could be your timing advance unit is hanging up.You could try plugging off the vacuum line on the right rear carb(it runs to the rear center of the motor) and see if anything changes.
If I'da known it would last this long,I'da taken better care of it.

All good suggestions, it's on the schedule for tomorrow. Deep down in my heart I almost know beyond a very uncertain certainty and a more than questionably questionable doubt, the previous owner rebuilt the carbs. There's no carb stay on either side, which means he most likely got the carbs screwed together crooked and the sync linkage is in a bind. I've tried all kinds of lubes, sprays, and yes even some jellies, all to no avail. The next step is to pull the carbs, check the bell crank, crank on the bell, wiggle this, jiggle that, and giggle all the way.

Thanks, yes, I've done that already. I've had the carbs out a couple of times, one of the floats was sticking, got that fixed, I'll see what today brings and let you know what I learn.
