I have an old B6100 that I bought used 2 years ago. This winter it started to get hard to shift and the clutch would not disengage completely. Then it stuck in forward. I pulled the top off of the gear box and the shift slid on the one shaft was tight. I honed that out and it now shifts fine but the clutch still will not disengage completely. I have adjusted the intermediate rod as far as it will go and have adjusted the end stop to see if this would make a difference. None of this has mad any difference.
Anyone have any ideas?
