In the seemingly never ending quest to modify and improve, my next mod will be to fill the handlebars (starting with the left since it's the worst, just to see if it makes any difference) with #9 lead shot to decrease the buzz in the 4k rpm range. Anyone happen to know how much shot is needed?
I had some plastic tubes that fit well inside the bars, and put some "bird shot" in them, (not sure what gauge number), sealed the ends with electrical tape, and slipped this "cartridge" into the bars. I didn't fill it totally full, my theory being let the shot sort of vibrate around and resonate or whatever. I never had much buzz to start with but it seemed to help. I think I got more results out of reshimming and torquing the engine mount bolts. Also I have the heavy-type Throttlemeisters. What I don't seem to have now is buzz. Whatever works for you.
If bars are not filled to 101 % full packed solid you can make matters worse; you want to stop the bars from ringing nor do you want anything inside ringing either. I'm with you on everything else including the Heavy ThrottleMeisters too.
Well, it was just a theory......I'd try pulling them out and do the pack-full style, but it's smooth enough right now I'm too lazy to mess with it. Thanks, Tony.
So did the #9 help?
NO, DON"T USE #9!!!! There is a weep hole on the throttle side that #9 can slip through
Front Fork brace and Murphs Bar End weights will do wonders also.
Where is this weep hole of which you speak? I had my grips off earlier this year, but truthfully never paid attention for any holes. The only one I know of is the threaded hole on the end of the bar which the bolt that holds the end weight threads into.
I've found the Genmar risers noticably increase the felt "buzz".
Getting rid of the "tuning fork" handlebars and converting to standard 7/8" did the trick for me. A KB bar adaptor and a set of $15 Bikemaster Daytona GP bars. Just saying in case the shot thing doesn't work out.
