Any one have any hints on how to secure bark busters on the bar. I have a pair of maier brand bark busters and it seems like no matter what I do they will not stay in the right position, the tend to flop down after the first slight hit. I've tried tighting the bolts equally on the bar, i.e. little bit top the bottom so I have equal amounts of space on each side of the clamp, then tightening end and any other combination. I even put some cut rubber strips from an inner tube inside the clamp area on the bar to give it more bite, and torqued them as tight as I can, and the things still start to drop down after a slight hit. I have acerbis on the xr and never had this problem. ANY HELP OUT THERE APPRECIATED.
