when tuning your cvt, take notes.  By  ramblinman (Read 374 times)

Keep doing it, it gets easy once you get it right once. I always use Dr pulley sliders and have several different weights all in the cases marked with grams. I run all my 50cc scoots with 5 gram sliders on stock variators and 6 gram sliders with koso or performance variators I run 9 to 9.5 grams with koso variators and 1.5k torque spring 7 to 7.5 gram sliders stock variator 1.5k spring and I always use 1k or stock clutch springs and never go over 1.5k on the torque spring tears up belts and awful to compress to change belts or weights. These are my formulas for the 50cc's. The 150s seem to run great with 12 gram weights stock. I'm running 11 and 13 gram mixed with a 1.5k spring had to lower the weights and add the spring to get my rpms up after the gear change.
