63 Tiger Cub Motorcycle

FRS 106, Michael Littman – Spring 2011

Tweaking

Above are two cams – the one on the left is the STANDARD CAM, the one on the right is the RACING CAM. We started using the RACING CAM but because of the extensive valve overlap, the engine was hard to start. After the STANDARD CAM was swapped in, the bike was easy to start.
