Hi Andrew, the total run out was 0.65mm, which is obviously a little more than the maximum prescribed of 0.03mm. Problem was caused by incorrect installation of the crankshaft and that’s on me being silly.
It not only effected how the timing worked, but indeed gave a very visible wobble on the slipring connexion.
I have a replacement crankshaft (the other one had it’s own problems besides the imbalance, and will be installing it properly and patiently.
Big lesson learntfor the future.
