That Yam wheel and cush drive are exactly what MMC should have fitted.

The rear pulley is a bit large, but getting a custom double sided one made of the correct size isn't impossible.

The lower belt guard would also seem to be a logical idea.

I'm firmly of the opinion (until I'm proven to be wrong!) that the lack of cush drive is at the heart of the bevel box problems.

Why? Because I suspect those people who have had no problems with the bevel box and/or rear pulley wear have a certain driving style that serves to protect the box from torque reversal loads derived from the rear wheel.

I will put off buying a M3W until this issue is resolved...by someone..
