I have heard from a good source that the rings that Image sells are chrome.  Chrome rings are NOT compatible with chrome bores. 

While dual rings are better for our application, the single ring design is proven to work good in the 550.  As long as the ring and bore materials are compatible. 

In my opinion you have 4 options:   

1.  find NOS pistons and rings
2.  have your cylinders nicasiled
3.  have your cylinders steel sleeved
4.  Use the other single rings & pistons that are available that do not have chromed rings.  (unfortunately these rings will not fit on the pistons Image sells)

hmm ok thank you gixxer6 .....
question... the chrome cylinders have been lightly honed .(not by me) .thinking they were the same as nicasil ...I'm guessing that is not the case.
Have these cylinders been damaged now?...can I go back to stock pistons and rings ?
I"ve taking my shellacking... now just trying to get things back on track .  >:(

While it’s controversial I’ve had great success lightly honing chrome bores. 

You can certainly go back to stock pistons.  I sent you a PM about a source for stock style pistons.

The local-ish guy that bought these from me went another route.  He wants what he has into them (same price that it in the original ad).  He might also have NOS rings to go with them at an additional cost, he is going to check.  If anyone is interested PM me and I'll send you his phone#.

so would it be correct to say OEM rings would (not) be chrome plated ?
considering the stock cylindersare chrome plated .

There are cast iron.  The rings need to be softer than the cylinder plating.  You may have 1 more ring option but I need to do some research before I say for sure.

Do the jet ski pistons have 2 holes near the top of the piston?  Just trying to confirm what you have?
