Thanks Jo Gutierrez. I appreciate the help.
And Jaykay I hear what you are saying. Funny thing is, the guys at my track that run the mtx-4 haven't had problems with gears stripping either. It seems to be that some of have the problem and some of us don't.
I'm definitely going to try a tighter mesh though. With the 3 I ran them kind of loose. But, maybe with the 4 you have to have them tighter. I am going to keep looking at the rest of the stuff i've seen on here. Thanks.
