I was elated to find a 2001 Arctic Cat ZR600 efi LE still in the crate with a great price. $3500.00!!! Put on 420 miles when I noticed that the front rear suspension shock was dead. Took it off and brought it into the dealer to have it rebuilt. Dealer said that it waqs full of black junk. Decided to have the rest of the shocks checked and they all were very dirty with black sludgy junk in them. I then took her out on a weekend ride when my speedo quit working at 620 miles. Tore it all apart whewn I got home to find out that the bearing behind the speedo was junk.  Is this all due to sitting in the crate for so long and if so, is there anything else I to be on the lookout for to happen? Any replies would be appreciated.
