Anyone figure out a good estimate on how much to shave off pad bump on a 3shoe clutch. I currently have an athena 70cc kit, bullet pipe and 16 sha with stock gearing set up. Don't have the paz springs but will be getting sme when Chris has them again. I put the stock springs on as they are pretty stiff. would shaving off 3-6 millimeters (1/8 to 1/4 inch) do me justice to grab at a higher rpm or is that overkill. btw, ill be running 5w20 or synthetic to give the clutch more of a slippier viscosity.
