CA72 vs. CA77

Post by bbraun » Sat Dec 08, 2007 5:48 pm

I just purchased a CA72, wet sump, in pieces plus spares. It came with an early CA72 tank as well as a late model one. I am wondering aside from the motor displacement and tanks for some years; are there any other differences between it and the CA77 or are most of the parts interchangeable? I don't have the frames and motor here yet. How about the carb? must be different or have some different jetting???

Thanks; Beth

I believe the bottom ends are the same as far as the tranny goes and other internal parts.Body parts are the same if I recall.I had bought a CA72 for parts.Clutch pack on the 72 I got had 4 very thick plates in it instead of the 5 plates like on the 77 .Jetting may be slightly different on 72 carb.I can't recall.I might still have the carb out in the garage if you really need to know I could root around for it?

Thanks for your reply; I will check the clutch pack and see what it looks like. Can't imagine why they would be different. I bet the carbs are different though. I have one in the parts lot; will measure to see. If your spare is handy and it's not too much trouble; could you measure since you know it is for the CA72?
Thanks; Beth

Only difference is the float jet.It has a 2.0 instead of a 2.5.Everything else is the same from what I can see.

Thanks! the carb that came with all the parts is completely different. I am cleaning it now and will post a pic when done. I've never seen another like it.

Is that YOU; ED MOORE? No; bowl is attached with a bale. Also; the body is larger than you would expect for a small displacement bike. It is a Mikuni and it has a model # on it now that the grunge is coming off. top is also held on with a clip instead of a screw on cap (where the cable inserts) and is rectangular!
Picture coming soon; it's getting clean quickly. - Beth
