Shaving a Speedo Drive Down

[headcoats]

I need to lose about 1.5mm off the speedo drive to get the KR1S wheel in RGV 250 forks. (to get wheel central)
Question is do i get it removed off the oiutside face or go the other way but you would have to mod 3 faces on the inside,the spacer,outside edge of the speedo body and the stepped collar that clips in the wheel to drive the cogs for the cable
I don't think taking it off the outside is the way to go as it could weaken it

at one point I shaved off one on the outside, but never used it . don't know how much though. will have a look for it, and measure. you can have it if you wish
