Is it a vibration or a buzz....I get a buzz and feel it through the whole bike, not just the handlebars. Fortunately it's just at this specific rpm and at that is only mild.
It was more of a buzz but it was bad. The whole bike as well. Mine was more than annoying on hands, it was feet, hands, butt, mirrors vibrating at very high frequency, tooth fillings trying to vibrate out etc. It was bad enough that you got the feeling that the bike wouldn't be long shaking its self apart. Now there is a slight buzz that I would associate with a large inline 4, before it seemed like a very real mechanical defect. Don't know if a sparkplug problem would normally generate something like this but I thought who knows, it fixed mine maybe it will work for someone else.
*************************************************************************My 08 has the same symptoms. My 04 didn't have near this much vibes or buzz. Whatever you want to call it. I call it irritating. Mine comes in around 4,000rpm too and it is the whole bike, not just the bars. Perhaps I should relax my grip with my butt on the seat, or my feet on the pegs. I guess I could just ride with them in the air till I needed to shift gears or brake. As for the Throttle rocker, I don't see what that has to do with vibes through the handlebar. My hand is still on the bar feeling the buzz. Been using the Throttle Rocker for 5 years. I can relax my hand, but it's still on the bar. Grip Puppies help a little, but still way too much vibes. And yes, I did a TBS right after I got the bike. Everything was spot on. I would be willing to try some new plugs. If it helps, good. If it doesn't, no big deal I was going to change them anyway. The naysayers that think these bikes all have the same amount of engine vibration are a little delusional. I've have owned 2 FJRs and they are night and day on the amount of vibes they put out.

I hear you. I test rode an FJR last year and it was smooth as silk. This sounds odd but the mechanic checked the TBs and they were on so he pulled the plugs to see if they were all sparking o.k. etc. He said that they seemed to be sparking from the back of the plug end rather than the tip (if that makes sense). He put new plugs in an took a look and he said that the old plugs were quiet and the new ones snapped very loudly by comparison. He suggested taking it out to see if there was any difference and there was a substantial difference. The bike still hums, buzzes or whatever as you get above 4000, but nothing like it did.

Pehler, I'm going to try the new plugs. It's close to time to change them anyway. I suppose it's possible they got a bad batch of plugs. I was hoping it would smooth out after a few thousand miles, but no dice. I'm at 8,000 miles now and it's as pronounced as ever. Gonna be hard to get used to that.
