Carburetor Lean Condition:
Some Evolution engines may run lean from the factory, leading to potential overheating or poor performance. Manual provides tuning guidance.
Primary Chain Tensioner Wear:
The automatic primary chain tensioner can wear out, causing noise and potential damage if not addressed. Later models may have upgraded tensioners.
