well as far a weak clutch...i would say that can be argued...but i would say it pretty substantial as far as a stock clutch would go...i aways used after market clutchs on my dirtbikes...(worked better for me) but again..if yer racing alot and shifting a 14000 or 15000 rpms its gunna wear it down a lot faster the just everyday driving. if its not burnt it still may be worn. i just changed the clutch with new oem....(if i have any probs with this i am going aftermarket) but i dont notice any hesitation.. (i burnt out the clutch on my 06 with 2000 miles...practicing burnouts and clutch ups on the bike
