Poor old MC28 owners......nothing but grief from the hardcore MC18/21 brigade.

Did you know that you can get half a hp at the back wheel with just a few (free) mods to the proarm hub?

Pull the hub apart and feel the amount of drag from the seals in that hub. It's shocking. On my old racer we carefully whizzed the seal lips away to get rid of the friction and used ultra light grease in the bearings. But then again, we had the hub apart after every race for cleaning so maybe not worth the hassle.

I know it needs all the help it can get, but it's just some useful info for anyone actually daft enough to want to race one.
