Awright guys?? Im looking at getting some Omega 18cc pistons but have been told the pins are 21mm. Most rods have 18mm. Does anyone know of any brand new steel rods for sale that will take these pistons???

Thanks for any help😉

Why would the pistons be so far removed from what normal rods would have ?

Surely it would be easier to get pistons that fitted in the first place ?

Standard rods have a 13/16" small end, that's 20.6mm so 21mm roughly.

I'm looking to purchase a brand new crank and a set of steel rods to suit some 18cc omegas but I cant find any rods to suit the pin on the pistons@13/16.

Any suggestions??

If the little end on the rods is larger can they be sleeved/bushed to bring back to a 13/16" gudgeon pin?
