Thanks Dave,
I'll try you suggestion on the pinion. I was kinda confused since last time I asked this question I was doubting which one to use.

Do you use any kind of heatsink on your motor ? Or have the bottom undertray cutout near the engine ?
I heard from a guy at my club your should set up the slipper by placing a wrench key in the pinion screw and rotate both front wheels. This results in the key getting stuck against the aluminium. You should then adjust the slipper till it just doesn't slip when further rotating the front wheels. Does this make any sense, or is there another way to set the slipper ?
Regards.
