Hi all, chasing a front caliper piston and seal for my 1977 K7 Honda 750 problem is they seem hard to get hold of, tried trusty old eBay (no joy there) Googled it still without any success, my only option now is you guys who hopefully will lead me in the right direction to a happy outcome, The caliper piston for the KO - K6 are smaller in dia am not sure about the F models another option if all else fails. Cheers Steve.
