piston i.d and tutorial????

so my bore kit is 71 mm and there is numbers on top of the pistons

4022ps
f38fo
xc
v :a direction arrow is where the v is ...there
is also a groove for getting at the wrist pin clip that is on the side instead of down like on the stock pistons...i am gonna try and post a picture of the top of the piston...i need help identifying the possible maker the guy i bought it from thought wiesco....also if you can tell a dummy how many cc's this pistonkit is goona be...i have a dammaged(bent) ring that i am gonna ask about later....thanks

this is a top shot....any clues would be great.....could a guy get just one ring replaced for this piston?

i have the bad ring ...it was flatened on one end of the c and mangled a little...no other marks in the kit anywhere...i think if i can get a ring..and go from there??

thanks folks...

71mm Pistons from wiseco use 4022 in the part number. Should be wiseco. see www.wiseco.com for a catalog of pistons, rings, gaskets, etc.
CC = 1045
to calculate take (1/2 piston diameter squared) X (Pi) X (Stroke) X (# of cylinders) / 1000

So 1260.25 X 3.14 X 66 X 4 / 1000 = 1045

It is a Wiseco and takes an XC ring

From Wiseco's Website Search for "Kawasaki" and "4022"

I ren into this issue a while back on an engine of mine that came with "C" stamped on the crown of the piston. The "C" was for "XC" rings, but no one makes a set for my 615 Kit. The newer kits come with the XA rings and are thinner than the XC. Piston Groove is too large for the XA rings, so I would need new pistons, pins, and rings. E-Mail or call Wiseco and see if they still make the type of rings you need. Look at the Piston Ring section of Wiseco's Website, and measure your piston and rings to verify what they list.


Good Luck

thanks guy's these answers help me move forward.....into 09.....peace

I believe we have XCs in 71 mm

well then...that it is great...let me look at my complete kit today and i will give a list to you of needs and my best attempts at a measure of anything(or should i go online at your site to order the items direct?)i believe i need some wristpin clips also...and maybe more...thanks a ton for the i.d too jay ...i'll respond and check responses later today.....peace
