Engine swapping.

(1/2) > >>

florence:
Does anyone know if the cb450/cb500t engine will fit into Cb350 K4 frame?  The bottom half crankcases look to same.  I have been looking on the internet to try to find another person mad enough to try but so far no luck.

Bryanj:
I think its too tall, but have never tried it. Any particular reason apart from a surfit of odd bits?

florence:
I have a 1972 cb350; it's a great runner but I find it a bit under-powered.  I was just thinking of a fun project to make something with a bit more go but still very cheap.  I guess there may be insurance problems....?

K2-K6:
There's a lot of that type of engine now raced in classic era stuff so some info should be available about compatability from that field i guess.

Maybe even a cam and carbs upgrade to make it rev a bit possibly? any 360T stuff to get closer to 500 power, don't think it was that quick antway.

Bryanj:
360 stuff dont fit the old 350 it was a majour engine re-design
