They were all crudely filed in the area where the friction plate tabs sit, but they should have been milled before they left Vietnam as failure to do so left them sadly shortly of their full potential.


Yes got a 47toothed one in my GP & did that one before fitting
Also got a 46 which is what I’ll use in this next build

Cheers


The easiest way of attaining a 46T crownwheel with sufficient depth for additional plates is to dismantle a pre-GP two-piece sprocket, extend the slots (a good electric file, such as Makita pays dividends here....) then reassemble with countersunk high tensile screws in place of the original rivets. The crownwheel will allow a tap to cut a thread in it. M5 if my memory is correct...... :roll:

I have modified quite a few of these over the years ;)
