Hi guys... last ride of the year, my primary blew apart. For what reason? Thinkin' last owner did not put clutch marks back together after dissasembling. But anyway I need to buy a new one. I found a brand new one for a 600. What ramps should I put in to work with my 2003 800 mxz rev-x, s8x clutch kit, geared down 2 teeth, 1.66 track? I never go to the mountains, mostly cross country, and by the river.
