Street Tracker
I'll try make a long story short. My '02 America has an intermittent "skip" and poor idle. It has about 20'000 miles on it since the 904 install (and British Customs cams), 45,000 total miles. I've been fighting this problem for about the last 5,000 miles. I have tried (over the last month) new irridium plugs, rejetting, replaced the carburetors, swapped the CDI and coils and plug wires from a friends bike that runs flawlessly, all to no avail. I checked the valve clearances (all within spec), and checked compression last night. Compression is dead even side to side. The problem seems to remain on the left cylinder only. The only thing i haven't checked is the air gap for the igniter pickup. I can't imagine that would cause an issue on only one cylinder, but haven't ruled it out. It is only a problem at idle. It runs like a banshee otherwise. I'm hoping that somebody out there can help shed some light on this.
