83 GL1100 CARB IDLE HIGH

Postby stevenstrack » Fri Sep 23, 2011 4:32 pm



I installed today a carburetor that i bought off ebay and had rebuilt this summer. I followed Randaks instructions and left the throttle cables disconnected, idle screw is adjusted 3 turns out (I also tried various other settings 1 turn, 2 turn out), I have the gauges to balance the carbs all hooked up, and adjusted the sync adjustment screws flush as stated in the instructions. The bike starts right up but I can't get the idle down below 3000 RPM. Does anybody know what I should look at that may cause this condition? I had some trouble getting one of the fuel tube passages clean on this carb set this summer but was able to clean it up. I just don't understand how the RPM can run so high without any adjustment on the idle screw. Anybody have any good ideas/suggestions?

AIR LEAK, HANGING SLIDE, thta's about it if no cables attached. note you can turn the idle scew out until it has no impact..the air screws on the carbs are actually fuel screws out equals more fuel.
HAD LOTS OF GOLDWING 75-83
NOW INTO 1500'S..RIDING A 1998 SE

FAIR WINDS,

Ok so I put my original carb back in and the right side balance was readiing about 30/30 for 1&3 and about 7/7 for 2&4. The fan kicked in so I waited for the bike to cool down and I thought maybe I should adjust the right side idle screws. WRONG ANWSER. The right side got worse and RPM's took off running 3000-4000. You said a stuck slider might cause high RPM. If a slider gets stuck will this cause both cabs on one side to read high? I thought this should be a simple task but it is killing me. Drinking a few brews to clear my head and watching games while I decide what to do next. These carbs I have in now were running ok before I tried to do the swap with the rebuilt carb...but now I'm wondering if the sliders were messed up in the rebuilt carb as well. Air leak??? where should I start???

First point...if the slides are stuck up,it will allow more fuel in that cylinder but not more air,so that cylinder won't increase the rpm that much.

I suspect that the left to right bank linkage is mis-adjusted and it is simply an adjustment.

There are 3 adjustments for the carbs,after the main screw.Look at the left bank linkage adjustment , it's on the left rear carb.
