4 stroke in Panther Frame
I'm building a bike for my girl friend using a '53 straight bar Panther frame. I was mocking it up last night and it appears that the motor will sit too low for the furnished 3 piece motor mounts to allow for much of a crank sprocket. I can make up motor mounts , but was wondering if I'm missing something. Someone must have put a 4 stroke in an old Panther before.
I remember seeing on some bike web site some smaller crank sprockets. Is that all that needs to be done? Is this one of those "all of the above" deals where the mounts, sprockets and other custom pieces need to be done?
