I have an F4 1000s - Power commander III, no cat, modified pipes.

The bike is a noisy as all hell, which is fine because I like it like that.

Anyhow, on Tuesday and again today ( I am not entirely sure this is just not in my head) the bike sounds like it is vibrating on the right side - almost like a rattle. Kind of like the fairing is loose on the right (it isn't).

This only happens on the overrun as I am backing off in the lower gears 2 & 3 once it gets down to 3k revs and less - sound stops at idle - the bike accelerates perfectly, sounds perfect at idle. It is however running hotter than it normally does, in this type of weather (getting cooler now), which is strange.

All fluids are prefect, coolant, oil. I checked radiators etc nothing is loose. Valve clearances checked at 12K bike has 19K & due again until 24K. Couldn't be could it?

Anyone got any ideas?

check the nose cone isnt rubbing on the top of the head light, its where the nose cone is at its narrowest point, right at the bottom of the windshield. It took me ages to figure it out, but the symptons were the same as yours! when your riding along and you hear it, grap the windshield and move it, see if the sound stops/changes. If that is the problem, loosen the nose cone (two bolts on the inside) lift it slightly and tighten it again. job done.

Also the mirrors will sometime make that noise, on the Brutale at least.

Mine was rubbing on the headlight. Here is how I fixed it.

took off the lower and side fairings, loosened the bolts that hold the mirrors, repositioned the nose fairing, then tightened the bolts and reinstalled the fairings. Also, a little bit of clear grease on top of the headlight where it rubs for good measure.

Just to put this bed - FINALLY FINALLY sorted this out - following the above just didn't work by itself ALTHOUGH YOU WERE BOTH RIGHT! So a variation of this worked - I pulled the nose cone off / took the the stays off the cone, screwed those in (the problem was a slightly misalignment in that little guide hole at the end of the contacts, it is so slight that it did not prevent the blinkers from working.

The tell tale sign was that if you tightened those screws a little too much the blinkers stopped working.

I put those stays in place (you need two people to do this) & attached the nose cone to it. The rattle is gone & you can tighten the nose cone stay screws as tight as you like without affecting blinker operation.

Hope this helps someone else in future who may have this problem & thanks to all you guys for your replies & help :yo: This place is THE best ;)

they are a bugger those nose cone stays. i have no front indicators at all because they stays have both lost their little dimples on the bottom which locate them on to the plates. so annoying! i need to buy two new ones, i did replace both of these already but they are second hand and when i got them the dimples were already missing. :(

I put draught excluder around the headlamp itself so that when I refitted the nose cone it effectively sealed up the gaps.:)

Yes I know what you are saying :(

Also going down this path kind of defeats the original Tamburini design of being able to pull the nose off & put it back on in 30 seconds. Still now that I know I have to follow a different process it's not that much of a problem just a little more fiddly I guess :) Thanks again for your help :yo:

Drill a hole where the dimples are supposed to be about the size of the dimples, tap the holes, screw in a proper size bolt and cut if off leaving the size of the dimples. Problem solved.
