Optimum snowmobile setup involves many variables, including proper clutching,engine tuning, suspension and traction. It's rare to hit upon the perfectsetup for all three simultaneously.
Upshift, downshift, engagement speed and peak rpm(for peak horsepower)are crucial. You don't have to be a psychic to know when your snowmobileis not clutching properly-though the messages may be at times subtle.
When trying to dial in the clutch that will deliver the response youwant, several procedures must be followed. First, ride and test in yourmost preferred conditions. Take note of clutch engagement speed, rpm spike,rpm creep, rpm speed at full throttle and upshift and downshift.
