I'm have 30's on my maverick and haven't drove it yet. I was wondering how the clutch is going to do with this set up for a while with out new clutches or clutch kit. So I proceeded to see that the new Xmr has 30's on it from factory so I went to see if they did anything to the clutch like new helix,different arms or primary and secondary springs. To my surprise the part numbers are all the same. So I suppose I will be good until I get the dough for clutches. Just wanted people to know this observation.
