Seems it is hitting the bottom part of the guide/bushing on the swingarm . . . regardless of chain tension.

If it does start to make some noise it's not bad and I know it's time to check the slack.

My swingarm was starting to show wear from the slider being pounded into it by the chain. Read the article. If left alone it looks like you could end up with a cracked swingarm.

Don't over tighten the chain to get rid the noise . You may ruin the counter shaft seal.

I've also noticed my WR sounds like the bottom end is rattling apart at low RPM, lugging it. Is this the sound from chain slap?
your chain is beating your chain slider into the swingarm, which in turn will wear the swingarm. we've seen some cases with extreme wear right at the swingarm weld line, so much so that a crack is starting.
this is what your slider is doing to your swingarm as a result of the chain slap and the gap under the slider:
basically, sand and dirt get trapped under the slider and then the chain pounds the slider (and dirt) into the swingarm. YOU CAN NOT FIX THIS BY INCREASING CHAIN TENSION -- you will just accelerate wear on your sprockets and transmission if you increase the tension.
read the 250F FAQ link which i posted above, ok i'll give it to you again -- http://www.thumperfa...hain_slider.htm -- and glue some kind of buffer material under the slider (i.e. USE SOLUTION #2 in the FAQ link, see pics 4, 5, and 6). the chain slider fix takes all of 10 minutes, only requires taking 2 screws out, and once completed will dramatically quiet your drivetrain. no more chain slap noise, no more wear on your swingarm. two birds, one stone, all done in 10 minutes.

Trust in us O followers of the TT... Take the screw loose on the top half of your chain slider, lift the slider up, clean under there real good, then just stick something soft to the swingarm under the slider. I used 3M two sided tape, it's like 1/16" thick or so, and it did the trick. MUCH quieter, and SO EASY it's ridiculous.
DO IT NOW!!!

As far as any sound it makes, I don't think the WR/YZ bike makes any more or less noise than other bikes.
dan, that's 'cause you always have your bike rev'd up so high, you can't hear it...
the rest of us are going slower and we can hear every bolt rattle.
