I figured it out, there was a rubber boot over the throttle lever concealing a thumb heater. The heater has been disabled.

I had a similar problem when i first joined, you were only allowed so many per day, didnt try for a while after that and then had no problem. I do get manuals that are hard to find at manualslib.com.

Morning. I'd missed that earlier post with the diagram. That washer and the one next to it work together to stop that gear 21 and 23 from moving length-ways. They are all cross cut gears though and there really isn't much end thrust; the washers are not doing much. I'm a bit dubious about them alone being the cause.. Once the gear is engaged, the roller should only be being touched if the gear had slid along the shaft a little, but it won't be pressing hard against it, or causing any chattering that could fatigue it.. I don't think anyway.. I'm presuming that the fork goes on part 20 ? I'd check that (20) fit on it's hub, part 21. I'd be checking it can't rock and allow that wear in the arch of the fork. I'd also check the fit of gear 22 on it's hub 23 looking for the same wear that would allow it to rock on it's bush 23. I think that either of those, if they could and were leaning slightly, as they would be to touch the fork, could and would chatter because of the three engaging dogs on part 20. If 20 was leaning over slightly, or gear 22 was leaning over slightly, then as the shaft and gears rotated the three dogs would force it, with some force, to keep trying to lean the other way once every 180 degrees of rotation. That force could chatter and break a roller..
