Well, I had a chance to look at CMSNL's web site and check one gasket, the cylinder head gasket between the cylinder and the engine case for both a C90 and a CT90 (1976 year), and both had the same part number... 12191-121-630.

So, maybe there could be some other gaskets that will have the same part numbers between the two bikes.

I'm guessing that the year of the CT90 may make a difference as we know there were some changes over time. And, the C90 dosen't have the dual range sub transmission, so that gasket will not be in the C90 gasket set.


Paved roads, just more needless government spending...
