Hey guys. Well I pulled the Shee out of the basement a few days ago, started right up was running great at the bottom end but right when it hit the power band it would make this sputter sound (Sounds like hitting a rev limiter in a car). Well I figure because the gas was sitting for awhile it was just shit gas. I drained all the gas filled it up with new gas and I switch to Bel-Ray MC-1 (Because my local store stopped carrying the Yamaha stuff.) I took it out for a few laps and it still wouldn't go into the power band. So I fired it up last night to mess with it for a bit it was idling and it just stalled out I couldnt get it to crank so I pushed it to the top of a hill and pop started it' when it fired up it had like 0 power at full throttle it would barely move. So I took the carbs apart they were clean (Cleaned them anyway). Still wont start
