What style of bearing have you got on the right hand crank end? Roller or ball-race?

Hi G

Roller bearings on the right hand side and as you can see in the pic ball on the left.

Sorry my mistake. getting confused with what you were asking G. I haven't put a picture of the crank yet, but it does have the rollers and the ball bearings fitted.

Some pics of the gear selector and the oil seal at the end of the selector. Doesnt seem to pass through the seal. Any clues on this one?

The bit on the end of the standard shift drum operates the neutral switch which isn't needed on your bike so you could just get a bung made to block that off. A simple aluminium plug with an O-ring should work.
