Got the bike running again only to find out that my speedo isn't working properly, I don't get any movement out of it at all (unless i go over a few bumps haha). It seems to be connected properly, and the bike isn't topping out at 5.5k revs, as would indicate a broken speedo so i'm at a loss as to what it could be?

Usually the speedo drive, I've just got one for mine. £9.48 delivered from david silver spares, part number 44808mr7013. Just a small plastic bit at the bottom on sprocket, two allen bolts whip the cover thing off and swap over. Pop it off see if its rounded off if so be that. Ive had 3 on mine now

I had a play with the drive and it didn't work when i took it for a quick test ride, came back did it again and fiddled with the cable and that worked!

But it seems that whenever i change above 3rd gear it will drop the speedo back to not working, however a swift hit or two will set it back into where it's meant to be... Maybe the cable loosened itself off again...
