I have a Honda CRF450 and the valves HAD to be adjusted at about 6 months after purchase. My diesel Ram's valves had to be adjusted at 60,000. Adjusting valves isn't unusual. Maybe the rest of us should be taking a look at ours? Jarrad, Silverbullet, Garth, Lenny & Flatbed, Do we need to be adjusting our valves at some set mileage in the life of out Trooper?
