I ordered new rings and they sent the following...the package says 3189XC, which are 81 mm and when I look them up it's a Kawasaki/Yamaha application. According to the Wiseco website, the K566M81 pistons use 8100XX piston rings. Are they the same/correct?

 

What is the differance between 3.189 inches and 81mm? This should answer your question.

 

The XX set has a higher tension oil ring than the XC set.

 

so that means I have to return them!

 

Depends on the tension you were looking for. Did you want 7 or 9 lbs,? How many mm is 3.189 inches?

 

3.189=81mm
3.199=81.25mm thats as far as honda recomends on factory sleeves so i dont know any more
you just need to figure your tension goals[proceed to engine builder for advice]
