Not sure on frequency of replacing parts. I can say he has it out at least once or twice a year. I recall he broke a lot of stuff when he had violent wheel shake last summer. I can say Liberty has been great with service and support. Cale was by far the best clutch guy to work with. He worked with a couple guys before and it was a complete failure. I personally don’t have the patience to deal with a manual transmission and clutch settings, it takes a huge learning curve ! good luck and enjoy the ride
