Excuse the massive title.
I was just on a 1000 mi+ trip with my FZ6 S2 and figured out in the first 200
miles that my chain was shot (I know). A few links seized up after 2 hours in
the rain and I tried to loosen it up with some WD40 and motor oil after but not
much I could do, the bike was riding rough and surging.
I replaced the chain (which was stock chain, whatever that thing was) at my
destination and put on a new rear sprocket which was shot. The chain and rear
sprocket had 20k miles on them. Didn't have time to replace the front (which
was a JT 17 tooth replaced some 8k miles ago) on the same day.
The surging was gone, bike became perfectly smooth, BUT, the chain had a
very loud noise (figured it was a bit too tight at the time). I thought that maybe
the front sprocket was worn more then I thought so it didn't "fit" perfectly with
the new chain and THAT was the source of the whirring sound.
However, yesterday I cleaned up the front sprocket area (it was a nasty mess)
and went back from the 17T to 16T new sprocket (also JT) and the noise is
now even louder.
I can't hear it that much when I'm accelerating, but keeping a constant
speed between 20 and 50mph the bike sounds like a military transporter
(humvee) on offroad tires. I was told that there's a bearing up front near the
front sprocket.
Could that be 'shot'?
But again, I must point out that the sound didn't come on over time and
got louder - it was there INSTANTLY after replacing the chain.
Ideas are welcome, and I'll swing by a yamaha shop next week so that
they can put an ear on it too.
Thank you.
EDIT: Local dealer says that REGINA chains tend to "sing".
