whirring noise now...
About a week ago I faintly heard this whirring sound.. Then the timing chain noise started and couldnt hear this.. it is louder on the right side but not too much more.. Now since the timing chain is silent.. this noise ia making me nervous... ANY suggestions feedback appreciated. Especially if she goes down I have to take the bus to school until the 'part arrives'... found this post at a r1 forum.. http://www.r1-forum.com/forums/showthread.php?t=300349 this video sounds just like mine.. Nine76Chris said... I had the same problem. Showed up @ 54K miles. Whirring noise at idle, which would get louder with a couple more revs. Lasted a few days then went away for a month. This cycle happened 2 more times. Bike ran fine, battery charging. It finally took a s@@@ after 3 months. Battery dead, bike died. It was the generator rotor. All the magnets had finally come loose and were stuck to the stator, no charge. I think when 1 of the magnets would come loose, it would be grinding on the stator. Once it was ground up, the noise went away and the generator would still charge sans 1 magnet. Tear you generator apart, just because it still charges doesn't mean anything.

I don't know what it is and I don't like it.
It's not the stator though, you'r is on the left and I've never heard one make noise. I'd guess cam chain tensioner is screwed up somehow.

The cam chain tensioner rarely fails. Also, Skibum tested his tensioner, and it seems to be working well.
I also seriously doubt the alternator has any problems. The Zong alternator is very well manufactured. Also, I haven't heard of any alternator failures for the TW200 or XT225 motorcycles. I suggest you check your exhaust header for loose bolts. Also, check the entire exhaust system for leaks.

My bet is also for a exhaust leak somewhere.

It almost sounds like the bendix in the starter hasn't released. Like the starter is being spun by the motor. I'm pretty sure it has a one-way clutch so that can't happen, but it sounds a lot like an electric motor to me.
