mine is doing the same thing cept my right cylinder is not firing. to me i believe its a fuel issue because i have good spark from both plugs (gapped at .040) and i have 125lbs of compression from the l.h.cyl ( the one that works) and 135lbs out of the right cyl ( the one that wont fire). I had the bike runnig last night, it would sit there and idle no problem with out the little tube connected that goes between the choke ports or whatever. the left pipe did have a good bit of white smoke coming out of it like it was loading up......so i got a piece of hose and put it between the carbs for the choke and now it wont sit there and idle with out hitting the gas and still no fire from the right cylinder, is there some stupid im missing or do i need another set of carbs or maybe something with the reeds, i just duno.
any help would be appreciated, thanks
