I was out playing in the snow last weekend with the cruiser. It wasnt the first time this year either. I had gone out a couple of times prior and realy rodded the cruiser. Anyway last weekend while breaking trail I was digging pretty hard when it sounded like a shotgun went off. One of the guys I was with said it was a birf. I finaly tore it down today and low and behold 4 teeth were missing from the ring gear. I run stock mini birfs with a lock right now. My question is with the 529 is there a stregnth issue? These gears have been in since August and maybe have 1000 miles. I did the install and the pattern looks pretty good. Any comments or help would be appriciated. ???
