Wheelie Difficulty

Cool b'head, the next thing you are going to have to learn is self-control now that you can wheelie at will!  

Best way to get a 600 up in the air is to get a power up kit (1 down, 2 up) with a 520 chain. When my R6 was bone stock I was having the same problems that you have, I could get it up but it took all the power the engine had and never wanted to stay up. I dished out money for a power up kit and a slip on Yosh and now I have no problems. Also a warm tire is helpful like stated in previous posts but also the compound of the the tire; the softer the tire, the faster it warms up and the stickier it gets... down side, doesn't last as long. Also, make sure you clutch is adjusted correctly and your slip point is instant, not when the lever is half way pulled in.
