I have a 97 XC-600 Monoblock triple for sale. This is a 97 so it has the fourth oil line to the PTO bearing. The sled has 3500 miles on it and has been left stock. The XC has the mikuni 38's. I will get some compression readings tonight. The sled was running great before my boy hit the only tree in the field. I would like to sell the motor complet(minus the clutch). $350.00 plus any shipping cost.
