all the guys that arent affraid of the lean thing will have this problem no matter what you have hanging on that side of the bike, the only way to avoid this is to, 1 cut everything that is lower or wider then the frame off on that side. 2 ,ride like a sissy and dont lean the bike over like you do now, or 3, lift the bike some to get more ground clearance that will keep the bottom from dragging, the stock bike will drag the frame in the same area if you dont have something to protect the frame ,and it will do the same on the other side, that is the pivot area of the suspension , so if you want a yamaha and a good lean then you will have to get an r1 or something if ground clearance doesnt do enuf for you . good luck , have fun , btk572
