i am thinking of putting it in, but mine wheelies alot with it out, i cant imagine howit will be with it in. i think i will just wait and put it in when i put my out shaft bearings in. i have to find a torch to get the screws out. does it wheelie so much that you cant punch the throttle?? i know you guys say that it is a 20 min job, but i have never taken it apart so i hope i remember where everything goes. thanks guys
