annoying rattle/vibration

Hello -

I have a 2001 F4 1+1. Purchased the bike with only 94 miles on the odometer, apparently it was the classic living room furniture in its previous life.
I am getting ready to turn it in for the 600 mi. service. At about 200 miles into enjoying this bike, an excessive rattle appeared. It seems to be coming from the right side of the front fairing and the right rear view mirror. I can get the vibration to stop if i push lightly forward on the wind screen most of the time...
I have added some rubber washers under the allen bolts that hold the rear view mirror on, put a little rubber spacer between the cockpit instruments and the shield, loosend and tightened down the 2 allen bolts that hold the front fairing on. The rattle is getting worse the more i try to alleviate the problem. Has anybody had this happen?
I am dreading the reply of "it is typical with these bikes". I love the bike more than anything, and just want the vibration to leave :-) I am open to any suggestions -

Regards,
matt

Interesting. My F4 had some rattle that I noticed when I first got it and rode it home. I can't remember what I tried to hold to stop it, but remember not stopping it. I've only taken it out twice, both longer trips with earplugs, so haven't noticed it too much. But I can't imagine it's just gone away.

I've got an after-market windscreen, so might be a different thing. On mine I can see a bit of rubbing of the paint off the screen near where the tach is. Not sure if it is related to the rattling noise...i don't think so.

anyway, i'll pay more attention to it and see if it still does it. I don't notice any vibrations related to it though.

Matt,

I have the same thing with My Senna 1000, around 4500-5000 rpm. In my case it comes from the air intake tubes that are vibrating against the fairing.

dismantle the fairing and see paint comes off. If so the problem might be there and putting rubber will solve the problem.

Good luck,
MotoMorfose

In case it helps I also noted a buzzing screen near 5K RPMs. Could minimize it by holding/pushing the screen. Left a message on this and someone mentioned tightening the Allen screws holding the screen. I did this and 90% of the buzzing was removed. Not even an issue now. Just mentioning it in case it helps.

Mine had a really weird rattle when I first got it that I swore was a fairing issue.

It was loose exhaust headers. I tightened them up when I did the thermal wrap on the headers. That fixed it for a while

Now I have a rattle again at 8000 miles, sounds like it's probably the air tubes, heh.

I had the exact same symptoms. Most of the time the rattle is from the front fairing not fitting correctly over the headlight (this is why when you press on the fairing upwards it stops). It drove me crazy for awhile till I figured it out. I thought it was the right mirror too but it wasn't. Take off the front fairing by undoing the two bolts holding it on at the base of the mirror stays. Examine the area around the headlight opening. You will probably see areas rubbed free of paint.

I had a rattle once on my CBR400RR that drove me absolutely crazy for months. I had the bike stripped down, even exhausts all off, and I revved it and at 5k rpm I'd still here this high-pitched metallic clatter. Then one day whilst riding and trying to ignore it I took my left hand off the bar and placed it on the tank and it stopped! Turned out the spring in the fuel cap flap wasn't strong enough and it was bouncing up and down at exactly 5k rpm. Never managed to fix it though...

yes! i have been concentrating on the right mirror for over a week now. nothing i do (little rubber o-rings stuffed all over to soften any shaking) has worked. i will remove the front fairing and look for paint wear. thanks for the tip! this has been driving me absolutley nuts...
