82 GL1100 Popping through left side exhaust.

Post by chrisk1965 » Fri Jul 01, 2011 5:32 pm

Just got this bike, haven't spent much time with it, but I notice at idle there is occasional popping through the exhaust. Is this a timing issue or valve adjustment issue? Or possibly something else specific to GL1100's?
I appreciate any input...

Mine do the same but only till bike is warm then it goes away. I have been told it is from bike resting on its side stand but I dont know if that is true, anyway I have had no problems I just let it warm up.

It not a warm up issue with my bike, it does it all the time,

and I only put my bike on the center stand.

1. Carbs Cleaned/rebuilt & Sync'd
2. Valves are adjusted.

I may pull the vacuum advance it may have a bad diaphram.

I checked vacuum on the diaphram and it does not hold a vaccum.

Mine is also the Left side, Front cylinder, checked all spark plugs, three are the same except left front #2 cyl. darker plug, not a light gray or tan like the others.

Bike runs great, really strong power, and No hesitation or flat spots, But maybe not advancing properly?

anyone else have this problem

i dont have this problem with my 86 aspencade but have similar problem including occasional backfire when changing down gears on my yamaha TR1, after being told by several mechanics it sounds like an air leak into the exhaust. After having exhaust off several times over a few years i'm sure there is no air leak. Finally found someone with a new possble cause. the exhaust valve may not be sealing properly, maybe due to carbon build up or possble damage. Have tried petrol addative carbon cleaner, but no help, valve adjustment wont show a problem and compression test doesnt help because its a minor leak that may show within acceptable tolerance. My current solution is to live with it and maybe one day open it up and find out for sure, a job much easier on my TR1 than my goldwing. Hope this was a little help although no solution.
