I also just bought/installed the two-brothers m-2 aluminium slip-ons on my 08 busa, they look nice and sound great but i noticed that the little ball attached to the shift linkage just under the foot peg comes in contact with the mid-pipe on down shifts making for incomplete down shifts. i loosened everything up and tried to reposition the mid-pipe as much as i could but couldnt get it to move much. so i loosened the 2 little nuts on the shift linkage and raised to shifter up but i hate running the shifter this high, anybody else with an 08 have this problem with aftermarket slip-ons?
