You could still get new OEM rings for them about a year ago. I ordered a set to put on the piston and cylinder I got from Manny.mic the cylinder, see what the specs are ?, compare the cylinder specs to the service manual specs ( which you can down load for free here on the site ), and if the cylinder is still within specs without boring it over ?, try a new set of rings. if its too far worn past specs ?, then you can bore it out, as long as you don't have to bore over service limits ?, your good to go. the problem you will have ?, is finding rings and piston for her !. keep us posted plz .
