I hadn't thought of just removing the fender. Thanks, I'll take a look at that this evening.

If I didn't need to replace the cush drive, I would probably just put on a new front sprocket and chain and go with it. The rear sprocket isn't showing any visible wear...but I've got a lot of play in the rear wheel, so need to replace the cush drive (and doing the rear sprocket) while I'm messing with it.
