This problem actually exists on my YZ 250. The bolt moves freely the further in it is turned. Right now I'm moving it out to compensate for my chain stretching. The further I turn the chain adjuster bolt out, the harder it is to turn. So much so that at this point a box wrench won't turn it. I actually have to push the axle in, so I can get a socket on the end to turn it. I've tried to spray some WD-40 on it and leave it soak, but it's a no go. Any recommendations ? ------------------ Matt W 00 YZ426F 94 YZ 250 http://www.mattwilliard.com "Don't worry about me, how's my bike ?"
