ZRX 1100/1200 noises, buzzes and rattles.

Hi folks. 
Down the page (in another topic) Pete had some rattles and buzzes and it appears that he now has them solved, which is pretty cool.
Just the normal shite like buzzing fairings, loose bolts (shudder 
) and radiator shroud/mounts. In his topic there are lotsa good ideas for keeping your Rex quiet and happy.
My '06 rex has 82 000 ks on it now and recently I've had a few new ones, which is to be expected.
First one. The carb-heat filter was rattling against the alternator cover, so I removed it and replaced the filter & hose assembly with a short length of 4.8 mm fuel hose which I routed neatly around the front of the alternator. Cleaned up the look of the engine nicely and the rattle is gone. The removed filter had nothing in it, so I'm not too worried.
Second one. Had a minor engine rattle at idle which was the alternator cush-drive adaptor screw loosened by a mere 1/4 turn. Removed alternator and reinstalled the drive adaptor screw nice and tight (to standard torque) with some locktite. Alternator back on and noise gone. Sweet!
Third one. Now, I may have caused this myself by washing the bike (carefully) at a car wash rather than doing it by hand in the garage, which is what I normally do. ( Du'h!
I was in a hurry, right.) Anyhow, now I get a high speed buzz or rattle at 3950-4000 rpm on the highway. It won't do it at rest with throttle, and the buzz comes and goes over bumps and stuff. But, it is definitely in the engine. Hmmm.. I think it may be the alternator bearings (unhappy at being wet) or the alternator fan. I'm gonna check tonight, but it is kinda wierd.
Anyhow, as some of the questions we get are about noises, buzzes and rattles, I thought we could share some of the things we know about this subject and especially with some Rexes getting some serious kays on em.
Cool.
Luv yooz all,
Woof.....
