Wah wah is driving me nuts
My '99 klr 650 has developed a pretty severe wah wah sound somewhere in the drive train. The frequency of the noise increases with the speed of the bike, not rpm. The sound seems to be coming from right under my butt, although I could be wrong about that. I replaced the chain, all wheel bearings, rear wheel is straight in the swingarm. If I pull in the clutch lever, the noise goes away. Any ideas? I pulled the engine today, but am wondering if I really need to split the cases. Could the noise be coming from the clutch? A bearing in the final drive? Sprockets don't seem a likely culprit since the noise goes away with the clutch lever pulled in.
The bike has ~28,000 miles on it.
