Alright I've been trawling this site for the last couple of days looking for someone else who has run into the same problem as I have. First off a little background info: I have an '03 shee pretty much stock standard 'cept for a pair of pipes, also i live in Australia so help and all that is far and wide (even from Yamaha dealerships... they know shit where I live).
I bought the shee about a month ago and it was running an it still does, no problem starting it up or anything like that. The problem lies with it misfiring on the left cylinder. Ive checked spark and it is there albeit a bit weak, I have a new coil coming this week. Fuel is getting there, just not being burned (tip of exhaust was saturated in unburnt fuel). Haven't checked compression out probably will later on today. I did take the carbs apart to clean em a while back but had no problem starting it after that. I read about puttin the slides in backwards and am going to check that today too it just doesn't seem to be a fuel problem.
Thanks for the help and sorry for the wall of text...
