Another little piece of information you might find interesting, There are 2 sizes of mainshaft 24mm and 25mm, If you have a 25mm mainshaft tou can replace the original mainbearings with NA49 needle roller bearings. These are 2mm too short so an extra spacer needs to be fitted between the bearing outer races, the inner races can be fitted with Locktite bearing retainer. I will let you know if this modification is reliable in service.
