I have a 2002 grizzly with 74 hours and 329 miles. What kind maintenance do I need to do other than oil change? I bought the 4 wheeler as a repo it had 20 hours on it. The guy bought it had it for I think 3 months paid it down to $5000.00 and fell over with a heart attack. I hate it for him and his family, but what a find. So now I have had it for a year I figured time for another oil change, but what elese?
