Thanks. I will have to look into that. Got my 67 Hornet project yesterday. Now the fun starts. With it, I got complete dirty motor, frame, a real nice STD cylinder, extra head, rear wheel, Hornet fork covers, clean California Title, extra side covers and some unknown BSA tank. I have a nice Hornet tank already. Do the 10.5:1 Standard pistons exist any longer? I don't know if it is an East coast or West coast model. Numbers are: A65HA13692 (frame) and A65HA13692-Y motor.
