Have located a '75 motor here in Oz, but would like to know if anything is interchangable between it and the '73 175 motor?
All i know is the '75 motor is silver and mine is black?
Also is anything else useable on the bike?
Regards,
Adrian
!975 and 1973 175 share many internals and the outer cases are shaped different. Same basic piston and rod. In 1976 and 1977 the 175 has a different piston and rod than earlier models.
