Looking for a Engine to fit my '78 CB400 frame. Either the original engine or one that will fit will work. Would prefer one that is good working order but would consider one that needs work. Thanks!
I don't have a motor for ya, but in your search you can look for any CB400 or CM400 motor from '77-'82 or the later CB/CM450 motors. All will bolt directly into your frame.
