Clutching suggestions for 550 XP?

I have an 09 550 XP which I recently installed 30x9x14 Silverbacks all the way around on the factory wheels along with a 2" SuperAtv lift and HighLifter springs, the bike has no problem spinning these tires whatsoever and does not feel unresponsive or sluggish but since these tires weigh about twice what the stock Terrathons weigh (40lbs/tire) I was wondering should I install a clutch kit or are there any tweaks for the factory system that can be done or will I be alright with the factory set up, any input is appreciated, thanks
