Too much vibration

Getting ready to head out for a 3,000 mile mostly solo trip.

Took a "test" run this evening to see if the V1/GPS/MP3 - thru Autocom worked.
Nope, it sucks. Getting that engine noise in the speakers.
Yes, I'll try a ground loop isolator next.
(bad thing is... I can't do this myself so may end up taking the speakers out of my helmet and just using the GPS and V1 for visuals and using the MP3 with ear buds. (my sweetie is out of town and can't help!)

OK, on to the vibration. This has been getting worse as time goes on. Only got the bike last November - new. Have about 7,000 miles on her. On my 40 minute ride tonight I was dismayed at the amount of vibration in my hands and feet. What happens when I ride this baby for 10 hours straight? I shudder to think of what condition I'll be in at the end of the ride.

So, I had heard there were some adjustments that could be made to limit the vibration. Please weigh in on this. I'll contact the dealer's service dept tomorrow and hopefully they'll come up with something.

when was the last time the valves were set and the TB's balanced?

She was serviced at 6.000 miles. Mid-May
I don't know if they checked the valves. Ironically, my dearest just bought some specific tools to do this, thinking the vibration' source might from there, but he is coming back from Laguna Seca the afternoon of the morning I leave for Colorado. Timing!! :(

Just remembered. The day after the service I was riding a private road with numerous water drainage dips. One of them was just a bit deeper than the others and I felt my bike scrape slightly. Although a visual inspection was done at the dealer and my dearest couldn't see or feel anything different when he test rode it - these guys do not have the intimacy I do with this machine. I felt a difference.

In order to address the problem with the installation of my autocom, I'll probably visit the dealer tomorrow. Hopefully they can look at the valves too..... if I plead my "emergency" case.

Keep in mind that if you want to do a valve adjust the engine must be dead cold... like sitting overnight.

The TB sync (which may take care of the vibration issue) is done with a hot engine.

If you drop off your bike for a valve adjust, you will have to leave it overnight to cool.

Woops there was a scrape? From where?

I was thinking that you might have a wheel imbalance. The way to test is zoom up to 70 and then pull the cluch in if it's engine then the vib will stop, if it's wheels or drive train (south of the cluch) then it will keep going. Does the vibs happen at the same speed or all speeds? Do you get the same vib if you are in 4th at 50 as in 6th at 50?. If so then it's not the engine. If you accelerate in one gear from say 3000rmp to 7000rmp do you pass through a band of vib or does it just keep increasing?

Thanks for the responses guys.
Called the shop and although they are overbooked, they will look at it for me. They doubted it was the valves - and thought it might be the TBs or even a simple problem with the forks and clamps - an easy fix.

So... I'll take it in and then try to figure out how to get 30 miles back to my house???

Damn timing sucks!!

The bike does not have to be dead cold for a valve adjustment; it just has to cooled enough so that head temperature does not effect the gap setting. If you don't believe me, try it during your next valve adjustment. Of course, I'm not saying adjust your valves right after a ride.
