I have a bare K0 motor case CB450E 1002311x and a complete CL450 first year motor -100602x. Can I swap the major parts over?

Thanks
Richard

If the CL is a 5 speed, and I think they all were (except for the CB450D model that had upswept pipes on each side), then no - the 4 speed CB crankshaft and how it mounts in the upper case is very different as well as having different shift drum and forks for the 4 speed trans. All 5 speed cases should be the same, but not the 4 speed

Thanks! for the reply. I suspected as such. it leaves me with a tough decision...repair the CL motor or find a K0 motor. Dang!

Here is a K0 motor that is pickup only, but might be worth the road trip if you can get it cheap.

Plus, the numbers (1021580) are really close to your frame number.
