81 GL 1100 STD

Postby bjcrit » Thu May 09, 2013 12:42 pm



I have an 81 Gl 100 that I have Synct the carbs, changed the plugs, adjusted the valves, new air filter, run carb cleaner though the system and the darn thing is still missing, hesitating from a stop. Poor fuel milage. The missing and hesitating is mostly noticed @ low RPM ~ 1000 - 2500. 2500 and up it smooths out. I went to adjust the points yesterday and I discovered..........no points to be adjusted.
Have a trip comming up in June and am hoping that I don't have to take it in to the professionals and spend my trip $.
Suggestions?
Bill

Just because it doesn't have points doesn't mean you don't have a ignition timing problem.
The 1100 utilizes both a mechanical and vacuum advance timing adjust system.
Changing the timing from tdc to near 38* btdc at 3k rpm.
Not too hard to test..."search" on the subject.

Sounds like the idle circuits might be clogged, at least on some of the carbs.

Sounds like a carb jet problem-syncing the carbs is a waste of time if everything in not absolutely "correct" ( timing, ignition, vacume ,intake gaskets-etc, etc).
Couldn't hurt to run some more sea foam, but I doudt that will fix the problem.
Have you checked that you are getting a good strong spark on all 4 ? Maybe vacume advance problems? regards, Johnyy

Probably your Fetzer vavlve. They tend to stick. Probably the humidity, or it could be the bypass line. You'll need some pliers and a set of 30 weight ball bearings. Prep it with some 3 in 1 oil and some gauze pads and you'll need 10 quarts of anti-freeze preferably penzoil.... no wait,make that quaker state. And don't forget to get the **** off those windshields!


















Just kidding......... Had to quote Fletch!

Hahahaha fulcrum!!! Had me going for a second! On my bike it was the idle air jets, you should take the carbs off and remove the jets and soak them in carb cleaner and then clean them... There are a bunch of tiny little holes around the jet that you need to clear out... I used a guitar string as suggested :)

Here is a pic of which is the idle jet once you get the carbs off.


Also here is a write up of rebuilding the carbs with a kit... It's great in identifying things you will need to cleanup and identify it your a po boy like me :)
