@Calum cheers... I know there are plenty of full sets including the stator generator but I was looking for just a new pick-up part due to the metal face being warn down by the tab on the flywheel when it came loose.
Once I can get the flywheel off I'll see how the current one fends - I might be able to manipulate it to still get the correct spacing for it to work.
This is what I was looking at

@AndyJay that would give you a 12.5 weight - I'd stick with stock unless the springs are too bouncy for you and some stiffer springs if you're larger than an average rider
Probably the switch for the lights as the tail light runs off the battery and the headlight runs of the yellow and black wire from engine, take switch apart and squirt some electrical contact cleaner on the parts or WD40.
