Since I'm new, I get to bring old threads back from the dead and ask a couple stupid questions, right? 
I rode my new to me '00 home 160 miles and it sounded mechanically perfect.
Started it up today and it sounds great at all rpms, until I drop it into gear and pull away. Sounds like a box of hammers being rolled down a flight of stairs.
Transmission? I've never heard of a bike going bad at 14k miles, but...
I wasn't thinking cam chain cause it doesn't make noise at a standstill.
You can kinda feel clunking too.... Weird.

1) When was the last time the oil was changed?
2) Does it make the noise in all the gears or just in some of them?

Well SH's really don't like dirty oil and the hard shifting might be due to it. Also it might have bad dogs on either first or second as most hamfisted riders don't hammer on them past the hard shift from first to second as it gets to scary for them.....

Just took it back out for a little jaunt to try and isolate it. What does the carb slide sound like? It's kind of a clunk-clunk when I left out the clutch and give it a little gas. Also, clunk clunk when I roll off the gas. I'm gonna need new plates, huh?

Well it could well be the carb slides. The hollow clunk sound is them opening and closing at low rpm.

Oil was flat nasty. Dark black. I filled her up with some fresh Amsoil Syn. and did 145 miles yesterday. No noise, of course, the Ipod helped with that. 
Really though, clunk either went away or became significantly less harsh. Thanks for the responses.

Got the valves checked and one was a hair loose but still in spec. Could be the source of my tick id say. My friend says if we shim the valve it would border the tight side so i left it for now. Guess i just deal with the noise and move on to the next wrench job! I really like working on these things Starting to get the hang of it

I still have the noise and no nuclear explosions as of yet. Mine is at idle,acceleration,deceleration but only through the first couple gears. Presently shes torn down at a friends getting a valve inspection/adjustment. Plus new cans, and probly tps adjustment. Down time.... poop.... I will report any findings though.

I hope that this makes sense to you - I am a bit off this morning.
On my other SH I ordered plates from a member who sells them in the classifieds - much thicker.

Yeah i just flipped them per everyones recommendation and put on the block off plates that were being sold on here for a while. I had the tick before that though. I removed all of that when i swapped the ccts.

mine started doing some clunking, knocking, and other weird noises. I did the TPS along with the other mods listed below(air mix, shim needles, sync carbs, etc.), and it doesn't do it anymore. that clunking/knocking sound is definitely scary sounding ****, but these engines do some weird things if everything's not right. It's kinda like a protest song. hahaha. i really don't know what the sound is caused by specifically, but I know that some part of what i did took care of it.
