I bought a 2000 Grizzly 600 with only 400 miles on it. When I took it out in the spring, it didn’t have enough power to get up a small incline. He mentioned he replaced a (crank?) seal that had leaked oil on the drive belt and it may have leaked again, possibly from sitting for a few months (I don’t know why it would leak again if a dealer just replaced it). I’m not that familiar with this machine, so I’m not sure what I may be in for. I thought the 600 would be a great machine but am a little hesitant now. I hope it’s an easy fix. Thanks for your help.
