I just got some acerbis rally pro handguards and started installing them but if I tighten the bolt that goes inside of the bars then it pulls the handguard in tight up against my brake/clutch levers. Any idea how to avoid that without cutting off the ball on the end of the lever? My other question is what to do on the throttle side? When I cut an opening in the grip I found that there is a plastic piece that the grip goes on to twist around the bar and the end of it isn't open other than a small hole. Do I just cut the end off of this plastic piece so that I can slide in the bolt for the handguard? Thanks!
