I am new to the world of SOHC 750, so please hold off on the laughter.
I have inherited a bunch of SOHC stuff that was originally modified to 65mm bore and used on 3/4 Midget cars.
I have also picked up a couple K model bikes. The first is a K2 that I have pulled the motor and removed the top end. My goal is to put the 65mm piston/cyl set in it. I have 2 F heads that have been ported and the chambers opened to allow the pistons to make the proper compression ratios (CB 350 + 1.00mm pistons that have been relieved for valves and coned). I also have 2 K heads that are in the same state of machining. I would like to use the F heads for the bigger valves in conjunction with my aftermarket cams to allow better flow.
My question is; Can I use the F heads on the K engines. If so, what do I need do to avert problems?
Thanks in advance,
Jeff K2
