Fett Brothers SKW010 Offset Timing Key - .010 Offset - 1.1 Deg. ARC

For Ski-Doo models early to present.

More power and acceleration with up to 2 horsepower gain. Degrees of advance depend upon stroke, rod location and offset. Simple timing option for fixed stator plates. Work with both stock and modified engines. Sold each with instructions. More timing offset equals more heat, so re-jetting will be required. Using premium fuel (91 octane minimum) with these offset keys is highly recommended.
