Ideally looking for anybody selling a second gear drive cog (16T) for an RM125 gearbox suits 90 & 91 (L&M) part number 24221-27C10. They're getting hard to get. Otherwise I'd get an engineer to make one. BUT they are much cheaper per unit with a bulk order.
If there are others wanting one then drop us a line. Its a long shot. I'll provide more details to anybody replying.
Cheers Brian Doyle
