Kickstart Shaft Oil Leak

[Raceman]

The oil seal on the kickstart shaft on my CL77 leaks. I replaced it recently and realized that the leak is due to the fact that the shaft has a wear mark on it where the seal rides on the shaft. The seal is a 14x25x7. Is there such a thing as a 14x25x9 seal that would move the sealing point farther out on the shaft? That should solve the problem.

And/or dress the shaft area where the mark with 1200 wet/dry paper or fine steel wool .
