The”pro-grip 714” grips are my go-to grips on my old bike restorations, they’re great ! But on the bikes with grip heaters that’s not an option so I go with grip puppies/buddies and they also help but do make the grip diameter bigger.
I personally do a TBS as yearly maintenance which does help the 3500-4500rpm buzz a bit, makes it less sharp with less amplitude but doesn’t eliminate it but imho makes it tolerable. Now on your gen2 you can also do the unauthorized tbs which is basically balancing the linkage of the individual t-bodies to each other vs just air bleeds on the gen 3’s,,, ,, BUT be aware that as Ray stated an in-line 4 has an inherent resonant buzz but doing a careful tbs or anything to balance cylinder to cylinder variances will improve it a bunch.
Also go over the bike to check the torques of the parts bolted on, on my bike one of the biggest improvements was that one of the mufflers wasn’t torqued properly and once properly torqued made a HUGE improvement.
My 14a (the fastest color red) had the worst buzz of any fjr I’d ridden but after doing multiple things the buzz is now tolerable. Besides the before mentioned tbs, grip puppies + torque checks I added vibranators (no longer in business) which are basically fancy bar end weights that use a tuning fork type deal to help quell handlebar vibes, I tried multiple plain bar end weights before settling on the vibranators.
One last thing, the guy’s at D&H in Alabama told me the best thing to improve the vibration was simply added mileage which at first I thought was pure bs, but once my bike had over 10k the vibration did improve with miles added. The above suggestion for adding throttle body/carb cleaner is also a very good suggestion, I use Lucas cleaner about every 3rd tankful, it does make a difference as well. My.02 hope it helps.
