I,m new to this forum,following a recent con rod failure on my '48 rigid framed A10 (1950 engine) I am in the process of gathering bits for my rebuild. In this connection I have acquired A large journal crank and already have a spitfire cam if needed and also have thick flange barrell.New A10 pistons tend to be much more expensive than A65 pistons, as I intend to increase the compression can anyone advise if the A65 pistons will work as direct replacements.?.....many thanks in anticipation of a reply (hopefully)
Photos would be nice!
now given a thick flange barrel is big fin, you also mention a sports cam...what state of tune are you aiming for? Keeping the iron head?
Cake Street Classics certainly used to stock wiseco pistons.
I personally avoid JP's like the plague.
I had a ride on a mates cooking '55 flash on New Years Day, delightful. Smooth as. Not a go fast bit to be found on it. Quite a different beastie to my methanol twin carb track bike, but no worse for it.
A65 pistons not an easy solution, the stock flanges don't have enough meat in them to go beyond 72.5mm
