Any of you guys know if the mounting is the same for a cb450 frame vs cm400a motor? I was just given a dismantled titled 1980 cm400 hondamatic. Looking to possibly build a chopper with a hardtail frame I see available. Had a cb450 in it. Am I asking for too much trouble? Will the sprockets line up without too much fabrication?

I think some of the motor mount bolts went from 8 to 10mm, but that's about it.

Not sure about chain line, it depends on rear wheel used.
