i have a 1999 500 xc and i was riding today in the fields when i noticed my speedo stoped working as well as my odometer. does this mean my bearings are gone or just an electrical problem. also i have reverse and today when i put it into reverse and gave it gase i could hear the gear grinding and poping. i tried it twice and both times it did this. it goes in forward fine no noise or grinding. what is going on with this thing?
