Welcome aboard mate.

I would replace the points if you haven't done so already, they have a habit of going on strike even though they look OK. This generic fault finding chart may help : Fault Finding Chart for Motorcycle Electrical Systems.pdf

Hi Jamie, Welcome to the forum. That's a nice project you've got. These guys should be able to help with parts/info : https://johnshirtmotorcycles.com/ If you would like to PM me your direct e mail address I can send you an owners manual and parts list which should help with the rebuild.

Good luck and keep up the good work

Hi, welcome Tezza It's a bit difficult to help without seeing the problem, it might help if you can post some photo's.

Thanks Genuine Seeley, it even came with a nice authorisation letter from Colin Seeley. I painted the tank cover and fitted genuine Seeley stickers and made a neat sidestand from a pair of Renthals, and generally tarted it up. Made a neater silencer It rode very well.

Or one of the many variations 😑
