Stanman Posted December 9 Posted December 9 Hello folks, I have just picked up an old GS engine, is there an easy way to identify what size it is? It's chain driven I took the carbs off and the O/D of the carbs is 34mm (engine side). The engine number is very warn and does not look right. Are there any other ways before I start to strip it down for a rebuild? Quote

BigT Posted December 10 Posted December 10 The capacity is on the front left of the motor, in a rectangle That's a 77-79 motor Quote
