210 smaller spur

[TonyM]

I read the ad and bought a 75T RW Spur to push the motor further back and get more weight over the rear end. The problem is that with the motor as far back as it will go I still need approximately 5mm more rearward movement before the 6.5T with a 20T pinion would mesh. I tried a 28T pinion and that still needed a few mm more.

So, two questions,
1. Has anyone managed to fit a 75T spur and if so what changes have you needed to make?

2. What is the smallest spur anyone has fitted without resorting to a Dremel?
