Cylinder sleeve

[billinater24]

I have a 1989 yz80. I am thinking about buying a cylinder sleeve for it to try to get it running. What all would I have to do to install the sleeve? Thanks.

HAve it bored to the correct size, index the port openings, heat the cylinder, pressin sleeve. Surface the top of the cylinder. Grind/match the ports.

Or Send the cylinder to a replater and have it welded and fixed properly...

Get it replated. Cheaper in the long run. If the cylinder is not origianlly plated get it resleeved.
