I picked up a Motorgo big boy do it yourself kit. It has a Caille power head and what looks like a Lockwood chief tower and l.U. on steroids. Ive never seen anything like this. If anyone has any information or pictures they would be a big help in assembling this motor. Gary.
Do you have any photos? It sounds like a 1930’s Model. I once saw what appeared to be a nice original 1938 Motorgo that was basically a Muncie/Neptune Master Twin, if I recall correctly. It was believed to be real even though it wasn’t supposed to exist.
the power head is definitely a caille, it dosen’t have removable heads. the power head is mounted solid and the lower unit turns. the top end of the motor is completely apart in boxes.
