1964 gs160 mkII barrel and head

How hard is it to put a ss180 barrel, head, and crank on to my gs? And what parts will I need?

Hello BlairPeach,

 

No problem at all as the engine is basically the same. So you can mount the SS180 cylinder, head and crank without any further necessary modifications. The SS180 has a somewhat longer gearing (1 tooth per gear).

 

Best regards,
