the 99cc ran a 41chain 10 tooth max torque clutch with the black spring for 3200 rpm engagement,with a 20 to 8 tooth on the jackshaft 45 on the rear wheel. Had the bike pretty much where i wanted.Then I burned up the clutch after 500 miles,probably was the 8 story cork screws in the parking garage LOL went to a cvt set up but i was gttting vibes off the driver because it had to be bushed up to 3/4 inch plus top speed of 34,I was also driving the kubota generator which cost me a few mph but i wanted lights. going to use the 99cc preditor on a different build it is a good engine but i dont want a max torque clutch.learning expeiriece.i have a new build i mind for the 99cc all belt drive.so all parts are getting reused . but it was all worth it to expierince the gc160 with the same gearing i had on the 99cc the 160 rocks using the cvt and im running the kubota geneator.and the best part she smooth as silk.
