Is the engine revving up? Could be the slipper. Make sure its tightened up enough.

If you want more bottom end power you can go up 2 teeth on the spur gear and if you want more top end you can go down 2 teeth on the spur gear but the 72 tooth spur gives you good all around power, also make sure when you rplace the spur gear that you get the mesh between the clutch bell and the spur gear right or you will be buying another new spur gear really soon, there should be only just a slight bit of play between the two gears, if it is to tight or to loose it will eat up the spur gear again....
