Carburettor-adjustment-question

Post by Dan Lumbye »



Hi

My GL1100 is a little unstable when i just start it. After 5 minutes it runs fine. I noticed today, that if i pull the choker, when the engine is warm after a long drive, the RPM rises a lot.

My question is: Is there something wrong here? To my logic, a warm engine should die (drown) when the choker is pulled. Is it a sign of a too lean idle-circuit?


Thanks in advance :-)

Best
Dan

No, the choke also opens the throttle some for a fast idle. This is normal.

Be sure that the carbs are synchronized properly before you go too much further. That will be a good starting point. I use, and a lot of people will suggest, that you put a few ounces of ATF in your fuel each time you fill up. This will help keep your carburetors clean.
