just came back from snowmobiling from weekend and my wifes indy 500 ifs arm broke at the bolt where it fastens to chasy. has any body had this problem before? i had this problembefore last year with other side , i just weilded it with a mig weilder to fix it. is this a common problem with polaris's ? also i have a regulator problem with it, it seems to cut in and out for the first few minutesand then run fine after for hours . almost every time you start it , thats what happens . last year i changed the regulator with a after market peace and it burnt out in about a month or so , and i ended up puting the old one back on.
