cyl head question 77K vs 77F
« on: October 01, 2009, 09:38:39 AM »
My brother just bought a 77K with trans or clutch trouble and a 77F parts bike. Are the cylinder heads different? How do they compare to K3 or K4 heads? cams also?

77 F head has larger valves, uses different pistons and cylinders. This has been discussed much. You can find more detail by using the search. The 77 K7 has a better cam than K3 or K4. The 77 F2 has the best cam of these you have mentioned.
