83 GS1100GL Idle Issue

[shagnasty]

The bike idles fine while warming up but after the motor is good and hot the tach shoots up to 3 and won't come down. I have tried adjusting the throttle stop in and out with no effects, I am lost on this one I have never had much luck with this type of carbs.

Sounds like a classic air leak. Typical suspect is the boot between the carb and the head. Could have a cracked boot, but most likely a bad o-ring between the boot and the head. New o-rings are available rather inexpensively at cycleorings.com. You might want to also consider getting the stainless screws to hold the boots to the head, as the stock screws seem to be made from something that resembles lightly-aged Cheddar cheese.

I will have to check for vacuum leaks around the boots. Where is a good place to buy new boots?

BassCliff will be along shortly with his little Mega-Welcome that is just chock-full of such information, but here is my list of favorite suppliers:

Alpha Sports
Babbittsonline
Bike Bandit
Carolina Cycle
Cycle Parts Nation
CYCLE-RE-CYCLE
Full throttle
Motogrid
MR Cycles
PartShark
Partsnmore
Ron Ayers
Z1 Enterprises

Alpha has a very nice search engine, but the highest prices. Bike Bandit is next in prices, then all the rest, but it pays to shop around.
