Hi all. Am tearing down the gearbox of my '73 Mk II 850 for a 30,000 mile inspection and happened to notice that the steel kickstart bush in the inner cover moves. It rotates tightly but smoothly in the seat as if it's riding on a film of oil, and the bush also moves laterally in the seat a bit, quessing .010 - .020". Is this normal? I assumed the bush would be seated tightly in the bore. I do not know what layshaft bearing I have yet, or whether that makes a difference to this issue. I do know the gearbox was serviced by the prior owner at approximately 15,000 miles. Thx in advance.
