speedo drive problem

jerry · 18-06-2019, 08:40 PM

reassembling bits of the M750 during its major refurb , got the wheels back from powder coaters so new bearings and cush drive rubbers in but after reinstalling the speedo drive ring and retaining seal according to photos i took 6 months ago the speedo drive does not seat properly and has now broken ,,

damn got to get another and they are rare as hens teeth according to dealers as my bike is a year 2000 model with 25mm axle ,,,I think i will need the drive ring and seal too but i worried about what i have done wrong ???

I have the original wheels from my yr2000 750 in the shed.
Can't do pics until someone visits with a camera phone .. and anyway you have your own pics.
But I can measure.
What do you need to know ?
