Yamaha 40 elj (1986) is in need of a piston one cylinder bore rings and gaskets. To get it done was guesstimated about 1500. If I get parts 3-4 weeks away. Do assembly with a mechanic friend prob guessing 800. One piston would be oversized I'm ok with that its old. But my question is is it worth it or just cut my losses. Anyone have a 40 or 50 for sale.
