just replaced chain & sprockets ??

Hi Guys,
I was doing some searching on here about this, but I'm not sure. I just replace the sprockets and chain on my 03 RM250. I put the same stock stuff on, 13t front, 49t rear, 520 x 112 chain. Problem is the chain seems entirely too tight and the wheel is as forward as it can go. Why would all stock parts be like that?? I rode it up my driveway about 3 times and just that seemed to loosen up the chain a bit. I'm lost.

the book i got calls for a 520x114 chain

well, looks like you are right. I just checked the online parts finder for a local shop and they list DID520DMA2,114LE for the stock chain. ughhhhh!

Go buy yourself a couple master links

For what it's worth! Could you not just use it anyway. The chain will end up stretching and then you will have you slack to play with. I could be wrong, but I know my last chain ended up stretching to the point where I had to take links out!

Good luck!

If the chain is too tight DO NOT USE it. You will end up ruining your new sprockets at the very least.

thanks guys, i ended up getting the 114 cheapy bikemaster chain so I could ride over the weekend. A few hours of riding and that puppy stretched out pretty far. The 112 chain was just entirely too tight.
