What's that noise?

93 650 L; 17,000 happy miles.

Sounds kinda like chain slapping but the tension is right.

Chunk-clunk-chunk mostly when I am in first or second, putt-putting.

Did not make the sound when I put it on the stand and ran it in gear.

If it's chain hitting something no big deal but if it is coming from inside, it is a scary noise.

Any ideas?

Cam chain tensioner no longer doing it's job?

Probably just the engine balancer backlash, not a problem, some make noise when new.

OK, what are consequences and is either one an easy fix for a guy who ain't real wrenchy?

My 04 started making noise down by the front sprocket during low rpm acceleration after a new chain, slider and sprockets. Everything is lined up and tight. I think it's because the replacement sprocket doesn't have the vibration dampners like the OEM. I guess I'll wait til it breaks, then fix it.

Did anyone figure out the clunking sound? I think I have it now too. I did a lot of maintenance over the winter so I can't say for sure what caused it. I changed front and rear brake pads. I also put a wave rotor on the rear. I changed the chain and both sprockets and now I have a clunking sound while putting too. I can hear it very well when I pull the cluch and just coast with no throttle. Sounds like the chain is hitting something but I can't figure out where. Tension is correct. Any thoughts?

Is the slider just under the swingarm pivot missing?

Weird that you'd hear it with the clutch pulled in. Something misaligned?

Swingarm bearings wiped?

Rear wheel bearings wiped?

Just guessing...
