Younggun has good suggestions but be very cautious about modifying tire/wheel size and more importantly offset(width)on atvs. Usually an inch increase in diameter brings little consequence but much more than that and there is a considerable increase in force through the axles, differential, and C/V transmission. We have all seen someone lose a belt in the trans, but I have seen the yolks fall out of the differential more than once, both times the atv had considerably larger tires installed. Secondly wheel offset, spacers, whatever makes your machine wider causes your stock shocks to be overworked. I encourage guys to feel the temperature of your shocks with extra weight or tire size/offset after a considerable ride on a bumpy or pot hole laden road/trail. You will be surprised. There are aftermarket upgrades available to compensate for the changes but they are huge money. Anyway I assume many of the hunters/fishers on this site can get a heck of a distance in the bush on there machine and wouldn't wish a breakdown that far late in the day on anyone. Just my two bits for what its worth.
