Hi i have a yz450f 2010 i just noticed the otherday that my swingarm is being eaten by my chain, and it is pretty damage. now my question is has anyone else had this problem? what did they do to fix it?, can it be welded up?. i dont really see how it happend as my chain is tighten right it has about 55mm play as the manual shows, but its it caused by having a too loose chain or to tight?
