1981 GL 1100 Low Idle Noise

Postby a3west » Tue Sep 02, 2014 8:21 pm



Hello, I just bought an 81' GL 1100 Interstate from someone who had it in storage since the late 80's. So I went through it and drained the old gas, changed the plugs, oil & filter, etc. but when I start it, it's pretty loud at low idle say 1,200-1,000 RPM and will stall if I let the R's get any lower. I didn't know if this was something that was standard with these bikes(still does it after bike is warm), or if I may need a carb adjustment or something? I pulled the plugs and did notice that the left side is running a little lean, but wasn't sure what adjustment screw to get it running a little richer. I'm fairly new to these bikes, and any insight would be greatly appreciated.
Thanks,

Sitting since the 80s means you are most likely going to need to rebuild the carbs. The noise is a common problem when the carbs are out of synch. In your situation I suspect it is more than that. Jets, air / fuel passages clogged up most likely. Slides binding, floats sticking etc. etc. etc. Go to this site and read everything about the 1100. http://www.randakksblog.com

If that bike has been sitting since the 80's, I would not start it again until you have changed the timing belts. Very important! Those belts have sat in one position for many years, in addition to aging, and are likely about ready to let go - which can destroy the engine.

'Impossible' is just a level of difficulty! The only stupid question is the one you didn't ask first!
