Hi there,
I have bougth a OS Giken mainshaft, but it does not seem to fit.
The distance between the circlip and the Inputshaft bearing is about 2.5 mm too long. As a consquence, the selector fork is not capable of engaging the 4th correctly (alongside the problem that the input/main shaft assembly is betting too long for the case & layshaft)
Is anyone aware of such an issue? Is this an manufacturing error?
