I fixed it. :)

The slipper was too loose, so when large amounts of power (such as first gear) or high speeds (such as 2nd gear) it just spins on the spot not taking the power to the tranny'.

Tightened it and fogot how mean my Maxx is. :D

I have a problem with first, where I can't do wheelies because of too much power, the wheels just powerslide and get no grip, not sure how to solve this?
