Hello, Well I now know why the bike ran just great at full-throttle/high-rpm times, and only so-so for the rest of the operating regime. Aside from valve clearances and carb syncing, the two o-rings around the jets illustrated in the attached photo were not sealing anything. The engine must have been running excessively rich for in-town riding, but I didn't really notice anything really bad. It idled well and was just a little rough at lower rpms.
I had already by-passed the air-valve and operated the bike for 2 hours at 5000-8000 rpm on a windy mountain secondary highway. Ran great for this short trip, but fuel economy sucked- literally!
I don't really want to spend $90 to $100 for carb kits. I do have all of the other required o-rings and float gaskets but these 2 o-rings (actually 8) are too hard to fit. Any o-ring I try is just a little too fat to push the jet into position... Ideas appreciated. Thanks everyone, Jim - a GURU-Wanabee!
