I like the long life of the O-ring chain in the mud and muck of midwest harescrambles, but I'm a little concerned about wear I'm observing on the case. I HAD run a 13 tooth last year, but when I saw how the case was worn, I figured the smaller sprocket was allowing it too close. I see that most people here seem to like the 14 tooth countershaft sprockets. Anyone else seeing wear with O-rings and 14T sprockets?
I'm thinking that maybe I can take some JB weld and rebuild the area to take any future wear instead of the aluminum case. Any thoughts on this idea?
