• Most common question asked? When do you ship? I ship when item is paid for, you purchase, I ship, PERIOD!
• This is a 10hp K241 .030 piston and ring set as shown in the picture. I also sell all the othe sizes on my ebay auctions
• This is alo for the M10
• This is for all K241 .030  engines, the suffix does not matter
• PLEASE NOTE THAT WHEN YOU HAVE YOUR CYLINDER BORED OUT YOU MUST HAVE THE PISTON FIRST SO THEY CAN MEASURE THE PISTON THEN BORE THE BLOCK! If your machine shop tries to bore the block before they have the piston, go to a differant machine shop because they do not know what they are doing.
• FIRST: You take your block to a machine shop, they will tell you what size to purchase
• SECOND: Then you order your piston, then take your piston to the machine shop so they can measure the piston, add in the tolerances and bore the cylinder. I've done this for along time and this is how you do it if you want it done right
•                  10hp K 241  The measurments are not for machine shop use. The machine shop must have the new piston to bore the cylinder.

  Standard cylinder bore........3.251"

  +.010 .................................. 3.261"

  +.020....................................3.271"

  +.030....................................3.281"
