XTD sucks ass... I put one in my bolt on DE and broke it in for 1k miles and first time I got on it, slammed into 2nd and it slipped... Had the XTD stage 3 from aimco clutches or w.e on ebay and seriously FUCK that guy... Wouldn't even own up to the waranty, just started acting stupid since I didn't install it till after the 30 days that it stays on the ebay...
