Yer' welcome.......
The SL350 K0 engine is essentially the same as any other CB/CL 350.
The K1/K2 introduced a number of changes - electric start is gone, and the crankshaft was "shortened" (width-wise). The kick start/tranny are completely different, as the K1/K2 can kick start in any gear with the clutch pulled in. Carbs are different, cam is different, frame and running gear are different.
Should you need a K1/K2 crankshaft, I happen to have one in nearly perfect condition.
