Balance factor for 500 cc single.

Post by Lars E »

I restored the engine of my 1928 AJS modell K8 last winter. With a beefier Matchless conrod and heavier bigend bearing the balance factor has change so that the engine vibrates a lot now. What would be a suitable factor. 90 mm stroke, 7.2:1 comp.ratio.
