lowering links or lowering a GPZ

The rim is wider and so is the hub. I machined down the shoulder the drive 
sprocket sits against and had to sink the studs deeper into the drive hub so 
they wouldn't hit the swingarm. This conversion also requires using the ZX11 
rear brake caliper and torque arm. The torque arm attaches to the RH footpeg

You'd have to ask Steve Northrop who has done the conversion.  I
understand it involves some machining.
