I have heard that one will fit in a:CB350 vs. CB360...that it will go one way but not the other & I can't remember which way they said it would work.
I have a 71' CL350K3 Engine that has been sitting for a while in a frame outside;I removed it from the frame(purchased it) & have it all cleaned up on the outside.I was planning on parting it out & it might have had loose plugs while it was sitting outside...it probably needs some work to get it 100%.I can sell it to you for $100 & then I'm not sure where you are to ship it to you.I would rather have a CB350 w/ a CB/CL350 engine than bastardize it into a mis-match...at least that would be my preference.
