need help 81 gl 1100

Postby sabrewing » Thu Feb 11, 2010 7:40 pm



I got my dads 81 gl 1100 and i pulled the carbs and cleaned and replaced the air shutoff vaulves. Now its back together and i can get it running but when i get down around 1300 rpm it starts running rough and starts slapping the drive chain and will not run under 1100 rpms it dies.. i have set the idle srews to 1 and 1/4 like the manule said and i sinced the carbs. I just dont now werre to go next . Dad said it ran ok when he parked it (8) years ago but it had a little power problem when he had to pull a hard hill or get on it when ridding two up so i don't know if there is more i should be looking at. hoping someone with old school know how with this old bike could help me...

A few ideas. Spark plugs, vacuum leak. I would perform a compression check on each cylinder, if the difference is within 10% of each other should be acceptable. The carbs probably should be totally overhauled. If you can get a set of vacuum guages or mercury guages check the carb vacuum and balance. All different finicky things about fuel delivery to the engine. Good luck; if all else fails read,read and read some more.
