Ill take a 160link non oring 520 chain please. Da good stuff. With 2spare masters. If its easier, i can paypal now so ya dont have to deal with cash...
In my honest opinion, this would of been hard to overlook as a seller. Id think seller should cover return shipping and issue immediate refund. But thats just my opinion.
What make you think its your mains? You said it rips up top but "sloppy" down low. Id look into pilots or that needle might be too rich. Most likely needle. Try cel.
