I have a stock re-sleeved 310 cylinder that has the L.A. Sleeve in it. Comes with a Like new piston and wrist pin and head gasket. Only a few hours on the piston and cylinder. Very fast cylinder. Looking to get about $275 obo but will work on the price if anyone is seriously interested.

Edit: i believe it needs a new head gasket. A whole top end gasket kit is $30 shipped from L.A. Sleeve for this kit.

its exactly on the 310 bore. I dont have the cylinder off the quad yet. The head was milled for the cylinder. Piston and rings are like new still.
