I have 2007 with 1100 miles, bought new from the dealer last October. I broke it in slowly and according to the suggested process. I've had several Interceptors over the years, but this one has an exceptionally loud gear box. Every so often I can achieve the "snick" sound we all like, but most it is a "thunk", even with the most delicate of throttle and clutch action. It should really be much smoother. Any thoughts?
