Athena will be good. Look on the bottom of your cylinder for a letter from A-F, that will tell you what size you will need. In reality any size will work though.

Thank you very much , appreciated .)

Your best bet is to measure the clyinder to get the right size, athena are good.
The top of your old piston somewhere under the carbon should be stamped ABC or D now i doubt your pistons a D especially if your still on the original lining.

vertex
