They go great with a freshened up carb don't they? the wear happens slowly so you don't realise how crappy the fuelling has got.

When I rebuilt my motor the axial play on the countershaft was at the limit - with new bearings - I double checked everything but couldn't find anything wrong. It's done 25K km since with no problems. Maybe get an accurate measure of it then check again after a few hundred km. Make sure the engine is at a similar temperature to get a good comparison.
