My wife wanted an ATV for pulling a small trailer in the woods to pick up fallen wood and branches and trail maintenance. I was able to get her a 2010 Trail Boss 330. It was a little too aggressive for good control at low speeds. It tended to take off too fast in forward and reverse. So, after replacing the rear caliper and brake line, rebuilding the foot brake master and replacing the starter, I dropped a tooth on the front sprocket to 10T and went up 2 teeth on the back to 42T and replaced the chain. This helped quite a bit. Then, thanks to very kind advice from Mike at EPIperformance, I dropped one spring rate in the primary clutch to blue/green. (they don’t even offer the spring in their product line) This did the trick. The Trail Boss clutch now engages at a lower RPM and combined with the lower gear ratio, it is much friendlier and controllable at low speeds in forward and reverse.
