Specific gear oil viscosity and type for the chain case lubrication system.
Brake Fluid:
If hydraulic brakes are used, the DOT specification for brake fluid will be listed (likely DOT 3).
Clutch Wear:
Common wear on clutch sheaves and roller/buttons, requiring adjustment or replacement.
Carburetor Tuning:
Carburetors may require periodic cleaning, adjustment, or jetting changes based on altitude and temperature.
Track Tension:
Improper track tension can lead to premature wear on the track, suspension, and drive components.
Engine Seals:
Potential for crankshaft seal leaks leading to air leaks and poor running conditions.
Arctic Cat History:
