I ran 28" Zillas on my brute; no springs or clutch work. Never had any problems. Very light tires.I think to go with Zillas or Big Horn 2.0, if I install 28" Zillas, Am I looking for trouble on my BF 750 with 2" lift, no spring mods, no chip, stock bike except the 2"? Or I should stick to go on 27"? Also, when installing new wheels, do you change de nut? Original one seem to be little big, or you still you the one of the bike?
