I sent my Bonnie crankshaft to a comp called Greenwood cranks donkeys years ago to be balanced and polished. It came back gleaming and the balancing drilling was opposite to the original .
i had an Owen Greenwood iron triumph t110 engine drilled timing gears , lightened pushrods and rockers , big inletvalves ,centre plugs , long inlet manifold
and balanced 1 piece crank
it was rev happy and so smooth
it had been in a grass track outfit
