4. Tension and Alignment of the Drive Chain
The torque delivered by the engine puts severe stress on the original equipment final drive chain.
The Problem: Premature stretching of the links is observed during the first kilometers of intensive use.
Critical Point: Excessive chain tension damages the bearing of the gearbox output shaft (countershaft sprocket), causing oil leaks from the adjacent oil seal. Keep the chain slack strictly within factory parameters (usually 25–30 mm of vertical travel).
