hi,

im rebuliding my 2012 yfz ( carb ) , i want to use the oem cylinder with prox piston and connecting rod kit.

from what i saw in prox site they have 3 sizes of piston:

94.95mm 01.2435.A
94.96mm 01.2435.B
94.97mm 01.2435.B

which piston do i need for oem cylinder?

and for the rod kit i didnt see rod for 2012 , only for 06-09 the serial number is 03.2436 , im guessing that is the same engine? so this should work for me right?

also please give me a link for good complete set of gasket.

thanks.

The connecting rod is the same from 2006 and up:

All the Pro X pistons I sell are the 94.96:
