Regarding the fuel gauge :- Sounds like a fault with the fuel sender unit. Doubt it's the PCB, with that year of bike. As for the speedo :- re- check it's fitted correctly. You could try, removing your speedo cable, pop the driven end in a drill to check it turns properly. If alls well, then re- fit it to the drive unit on the wheel, spin the wheel, to check the drive unit's working properly. I've also had this type of problem, discovered I'd not fitted the cable properly at the back of the speedo. It can be a bugger to fit it correctly. Also, if you battery's a bit flat, this will effect your speedo reading ! Regards, Len.
