How much does it cost to rebuild the top end on a yz 80?

[Jesse Dominguez]

or how mcuh will it cost to just buy a whole new yz 85 motor????

[rockbase]

the whole bike isnt much more then 3,000.00 I would say it might cost depending on whats bad, about 600.00 for top end and to buy a whole engine NEW (engine power kit 845.00) if you could get one would probably ** 1800 to 2000.00 us dollars
