I think the OEM Yamaha pistons for this sled are no longer carried or cannot buy them anymore from dealer.

What pistons do you get? I dont like the OEM ones anyways because there is only 1 ring per piston. I saw a set on ebay that was made for 2 rings but appear to look like they are the wiseco type. Very shiny looking. I guess maybe have them coated? Why would they only make 1 ring land on a piston?

I just installed Wiseco's in my 78 that I got through Dennis Kirk. As far as why just one ring my only guess is because it's all you need.
