Hi Neo,
Used a band saw, drill press with a hole saw and a router bit to produce what Honda did not want to know existed. Its a bit hard to work with but it keeps the greenies happy.

Hi fish,
I bought a block of nylon 80mm dia by 300 long and made 2 blocks 50mm long for my bikes. Cost $45. The rest is in the shed, if you or rob need some give me a hoy.
