Known Issues
|
Common Wear Items:
|
['Drive belts (cracking, stretching)', 'Suspension bushings and bearings', 'Track lugs (tearing, wear)', 'Carburetor jets (clogging)']
|
Potential Engine Issues:
|
While generally robust, issues can arise from improper oil/fuel mixture, overheating, or lean jetting leading to piston damage. Crank seals can be a wear item.
|
Clutch Issues:
|
Sheave wear, roller wear in the primary clutch, and worn buttons can lead to poor performance and belt longevity.
|
Steering System Wear:
|
Handlebar bushings, steering post bearings, and tie rod ends can wear, leading to looseness and imprecise steering.
