thats why you proubly cant ride wheelies, my 27" executioners weigh around the same of vamps and it was very hard to pull mine up with out the clutch kit. but i dont want to be the one that tells you to go out and get a clutch kit because i have heard people say that they were disapointed with them,but i was verry happy with mine. so maby you can get some info on them and see if you think it would help and if you think it would then maby you can try one.
