I bought a new pushrod from Peter at BSA unit Singles, and it and the intake pushrod are both straight and true. The damaged pushrod I removed is now about 8 inches long, as opposed to the normal 8.25â€.
I’ve attached pix of both the intake and exhaust tappers and I don’t remember there being much difference between them before this.
I know I could probably just use a longer 8-3/8â€ square barrel pushrod but I think something else must be going on.
I wasn’t thinking of bending the rocker, I thought perhaps it could have been bent during running when the pushrod shortened?
