My opinion...I wouldn't pay 200 for a pist/sleeve ,If I put out that kind of money ,I would just buy a Picco or another
Os or LRP! If the pist/sleeve is not damaged ,you can send it off an have it re-pinched for
about 30 bucks!...

For pist/sleeve resizing service. You have to send piston & sleeve in a padded envelope!

Paying to get a new piston and sleeve is not worth it. You could get it re-pinched, but remember to pay no more than 50% of the price of a new engine to get it repaired.
