If you over fill the clutch with too much oil can it affect performance? We just recently got our garelli super sport XL finished and i just poured in the oil till it started comming out. I think the manual calls for 13.5 fluid ounces. the bike is not running as fast as it should its only doing 22-25mph. I can't think of anything else that might be causing this. there are no vaccum leaks. theres a new plug. cleaned carb. checked timing. electrical is good. exhaust is clean. soooooo WTF Mate?
