any mods that should be done asap on a used griz 660 to extend longetivity?

 

What year? The 2002 and 2003 needed the recall side vented plastic side covers due to a boiling gas problem.

My friend bought a new one in 2003 and still rides it all the time. The only thing he did was change a spark plug once,change the oil yearly and buy two batteries in 10 years. Even the belt is still the orginal.

He also but on bigger more agressive ITP Mudlites XL(1-1/8" lug) 26x9 fronts and 26x10 backs it gave it a meaner look and more ground glearance.

 

sweet! this one is a 2008 so we should be good after a thorough checkup.
