I know this is a tough one for an internet board but here it goes:
About 3 weeks ago on my way to work I noticed a "whine" develop. It was definitly not there and then all at once it was. From what I can tell it is:
1.) Most noticeable in 5th and 6th gear (when I am going releatively fast) but I hear it more faintly in 3rd and 4th.
2.) Seems louder when I am in a turn. Right or left: doesn't matter.
3.) I can just barely hear it under the exhaust, but when I am between 2000 rpm and ~2300 and I have the throttle in such a position that I am just maintaining speed, (not decel rumble or acceleration, that "quite" spot I can hear it best. It doesn't seem to get higher or lower in tone with speed. Just a constant tone.
No problems shifting. All fluids are spot on (Mobile 1, Spectro 6 speed, Spectro Syn Chaincase). Tightened/checked the belt yesterday. Checked tire pressure:in specification. The only other thing is that I have the original front tire and the tread is starting to get low. I want to wait a little bit more for the rear so that I can have both tires replaced at the same time. I wouldn't think that it could be the front tire with lower tread. (High tread would make more noise, I would think).
Any thoughts before looking at something more involved (transmission)?
Plan of attack for diagnosis?
