you need to look at the numbers stamped into the bottom edge of the cylinder.

it will be like 2070, 2040 ect.....

hell otherer from what you say on the one i have it says 2070 on the bottom of cylinder . there is a sticker like on the outer of where the pull start is that is saying
carnt read first part but 6230rc1 dont know what that means on the one my son uses which is 26cc that no on is saying6260rc1, think the front part of it reads gs making like the lable on the outside where his pull start is but his cylinder has same no as the lepard

FG uses Zenoah motors with an FG lable on them. the 230 would be a Zen G230RC (23cc) motor, while your boys would be the Zen G260RC (26cc) motor.

thats assuming it is all stock and the crank is also a stock 28mm stroke. only way to tell the crank stroke is to open the motor and look for 1mm or 2mm markings. but if it is all STOCK, then rest assure the crank is a stock stroke and your motor is a 23cc.

There is not a huge difference between the two.

You can see the 23 zenoah engine, it is labeled 23. I think that there are no big difference about them.
