does anyone else experience that after popping about 4-5 wheelies in an afternoon, you lose power in either the clutch or engine and your bike doesn't want to go up anymore? it doesn't matter how much gas i give it, it just won't come up. i've had this problem with my 99 zx6r and my zx7r now.. i've talked to burnaby kawi and they said it might have something to do with the oil not reaching the front end. after the bike sits for a long while it kinda "refreshes" its wheelie ability. i don't know about throttle wheelies but does anyone doing clutch wheelies experience this?
