Yep, my '05 ST does that and has since new. At 33K now I rarely notice anymore, but it's pity it has to go and blur your mirrors in exactly the part of the band where you're likely to spend a lot of your riding time. I wonder why we don't hear the equivalent RT guys complaining about it? Guess those big steer-horn bars must absorb most of it and of course their mirrors are on the fairing.

The only thing I changed from stock on mine apart from a recently acquired Ermax windshield is I had the seat rebuilt. That slightly domed shape and thin padding meant the pressure points on my bony ass never shifted no matter how I moved around. Which meant I needed a walking around break after 90 minutes, and then every hour after that. All better after the rebuild, I can ride forever now.

I was thinking that buzz was around 3,300?? I attribute it to the counter balancers as it reminds me of an inline 4 cylinder. One note I'd recommend upshifting when available out of that RPM's not only to avoid the vibration, but to get back into the mid-range torque band which is stronger between 3,100 & 4,500 revs anyway. thumbsup

After a couple tanks of gas and some Seafoam (and a spirited 300 miles to see Mt. St. Helens) the buzziness has gotten better.

The seat sucks.

The seat doesn't need much, just to be built up a little with some dense foam so as to be flatter or slightly dished in the wide part -- dished roughly as much as it is domed now. I went to too much trouble and expense with mine and now it's actually plushier than I like, and it also spoils the lines a little. As long as you're not always perched on the same two points of your buttbone and small shifts of your weight move the pressure to different areas it's good to go.

Oooops! I guess I haven't really paid much attention to the vibes lately. That's the smooth rpm's. I do work around the flat upper mid-range as a matter of habit because it pulls so good in any gear between 3100-4600 revs. Mine runs ok at 2700 to 3k but does vibe some and pulls much better just above that.

I think mine needs new plugs. It's not happy pulling hard and seemed to stumble in 6th the one time I got above 90 mph yesterday.

I tend to keep the revs up on twisty roads. Above 4K most of the time. 5K seems to be the sweet spot.

Hi Dennis,
Not sure on your service history etc. Proper valve adjustment, throttle body sync, fuel condition & injectors performance (clean?) and plugs I guess could be at fault. I have iridium plugs in mine and the throttle response is seamless within the power bands of this somewhat highly tuned engine. You're missing one of the endearing strengths of the hexhead by staying that high of revs IMHO. Get on a curvy road it should pull pretty strong in any gear and with great control between 3100 & 4500 while achieving near go to jail speeds. wink I only need the 6-8k rpm band for a fast high speed pass.

It's wasted effort to try to sync the throttles before checking/adjusting the valves.

Yeah, that is true. Autumn rains start tomorrow, like a switch. Where Friday was 75 and sunny next week will be 60 and wet. There might be 3 or 4 riding days left between now and November when it gets really wet. I had a good ride Friday, got to enjoy my new bike. I've all winter to learn how to make it run nice.
