sounds like you have a brand new bike and the chain "broke in" (normal initial stretch) Mine got really loose after about 3rd or 4th ride and was slapping all over the place.

as said above, check your slack.

hmm actually i have the same exact bike, i havent noticed it grinding on my frame. but if you look in the manual it will tell you to measure 15 links in your chain and if it is past a certain length then its time for a new chain... and im sure its way past that. or you might need to adjust it

i ajsted it 3 times the past 2 days and the chain is 3 fingers loose thats it and i can see it scraped some more of the frame i mean its not bad but i want it to stop but the yz frame is so much closer to the chain then ne other bike by far it seemed like i had this prob as soon as i put a new tire on my bike but its the same model tire and i put it on perfect ,it seemed as soon as i put the tire back on i needed to ajust the tire back about 4 dashes and a chain canot streach over night

Do you use a lot of engine brake? This puts a lot of slack in the top of the chain. I noticed wear on the inside of my subframe so I made a stainless guard for it.

The chain hitting the frame on that bike is faily common. It's caused by the chain being too loose, or the chain is wore out.

Stock chains don't last long on 450's.

i noticed when i changed my chain from standard to an o ring chain it started rubbing on the inside of my swingarm. immediately removed it and put new standard one back on. no more problems.

Stock chains are garbage. I had to adjust mine on my new 98 KX250 every time I rode. Get a new chain before you kill off your sprockets.

The stock chain is junk. Replaced mine before I ever started it. Also, it is best to use a straight edge to align the wheel. If you do insist on using the marks on the axle blocks be aware that they are to be read starting from the rear instead of the front mark.

Stock chains are, in fact, junk. However, the chain will hit the frame even if the chain is in good condition and a high quality part if the rear wheel is not correctly aligned. Don't go by the blocks until after you check the alignment to see if they're right or not.

how would you go about properly checking the alignment? Ive noticed wear on my frame and my swingarm also.

Don't worry, it happened to my '06 too, the wear will slow down once it's worn a nice little curve into the frame. Making up a stainless frame guard like bg10459 did is probably the best thing to do. My rear wheel is always straight and the chain is always adjusted. My chain eats the frame and the shock mud flap(yours probably is too), so the chain is bouncing to the left side and to the right. You'll probably also notice that the chain eats the knobs on your tyre too. If everything's adjusted properly, it probably just means you're just riding the bike hard like it should be ridden! A new chain won't help the problem, but most people agree that the stock chain is not very good quality.
