I worked for a shop back in the seventies in stockton CA, Jorgy's of Stockton, at the time Alex Jorgensen Gran National #44 was riding for Ron Woods on a Norton. he also rode his father BSA,and raced Can-ams like this on a national level. His father along with employees such as myself built these can-ams, for sale locally. If you are familiar with dirt track racing the shop also sponsered Chris Carr, who rode 370's and 400's in boss frame's. This bike is extremely rare to the fact that Champion built this frame for this engine with the oil injection in the frame. Frame is marked #2302, Motor has been set up for pre-mix.The bike is extremely fast and handles excellent, and is ready to race.
