Mike,
Initially it does cost more, but we have blown more tag motors than shifters in the last 2 years. 2-0. Both were bottom end failures. We did have a learning curve in the ICC also. Once Kyle took over the motor tuning, carb in particular, we have not had an ICC motor failure. If I could appoint a mechanic of the year I would name Kyle. He not only drives well he saved me a lot of money on engines.
Enough from a proud papa, back to the JR1 saga.
