Andrews A2 Grind Cam For Big Twin

The Andrews A2 Grind Cam is engineered to boost the mid-range and high-end power of your Big Twin engine. Experience enhanced throttle response and overall performance without sacrificing a smooth idle. This cam is designed for easy installation and reliable operation, making it an excellent upgrade for your vintage motorcycle.

Beskrivelse

This Andrews A2 Grind Cam is designed as a bolt-in upgrade for 1966-1984 Big Twin engines (excluding 1980-1981 models) seeking improved performance. It delivers a noticeable increase in mid-range and high-end power without compromising the engine's idle characteristics. For 1980-1981 engines, verify that stock H-D valve guides do not restrict spring travel, and that clearance at the main bearing boss is sufficient. Spring travel and clearance should be checked on 1980 and later models. The A2 Grind Cam offers a blend of increased power and ease of installation, making it a popular choice for enthusiasts and professionals looking to enhance their vintage Big Twin motorcycles.
