At 8,500 it cracked a rear shock and Polaris replaced the rear shocks , from what I was told the housings were to thin . 12,000 secondary clutch . Other than that just regular servicing .
I raced 2-3 nights a week back in the RC10 days . Raced 2WD RC 10 , 4WD Yokohama , 2WD Truck . Was a lot of fun till I got hooked on circle track racing in real cars .
