I've heard differing solutions to the age old problem of excessive viberation through the handlebars from stuffing the bars with something to using spray in expanding foam(Ski Doo rider,we all know how well their warmers work).Has anyone found a solution that offers any real relief?I've actually thought of doing the spray foam thing to try it but that's kind of a permanant solution,once that stuff is in there it's there to stay.If memory serves me correct somebody had a rubber insert you could put in for vibe reduction but I haven't seen any adds lately for this.What if anything have people been using?Thanks
