Re: 4g belt drive slipping like crazy at 75% and over. Do you know whats wrong?
Just got a new 4G motor and the cluctch lasted 5 miles and it was done,when I was riding it it disingaged all by its self. After 45 years experience with motorcycles and a racing back ground and having (Chuck Sun) @ KTM ask to borrow 620 4 stroke for Joe Kopp to race super moto I think the design should have been a V belt design insted of some brake pads in a drum. There is too much slippage with the clutch on the 4G which will go through clutchs too much. The pressure plate design works really good and is used on dirt bikes and such. I am looking for a stronger clutch than the stock 1.
