Now about kickshafts. My E43, E66 and Kerrys E122 has a kickshaft with a small hole in the middle as most have. But, E302, E407 and E636 has the kickshaft with a bigger hole. Peculiar that Honda started with small hole shafts, later mounted bighole shafts and enen later Went back to smallholed shafts again.
If you look at the kickshaft with photo taken from above you can see kickshafts was zinced from factory.
