1986 430 Hubs

so I see the argument for these on an auto
i understand putting the brake on the bars, but my clutch is there
has anyone done this to a standard model?
I have a 92 rear wheel, I was looking at milling the swingarm for the slightly larger axle and the stumbling block I see is the fluid reservoir
where would you mount that and be able to have visual access for pre ride checks

I have done exactly what you are asking. It was actually really simple too do and works perfectly..... I do have to fix mine though (got a little carried away with the grinder)

I believe the hub for the 2001 WR426F is supposed to fit in the frame. I haven't purchased them yet, but that's what I am told. Does anyone have the measurements for the gap on between the forks and the gap on the swing arm? If so I saw the dimensions on the hubs for the Yammie somewhere.
