23cc cy head fit a 26cc zenoah engine

[nightwolf24]

hi all ime new to the forums so bear with me ive got a zenoah 26cc engine,and it was very hard to start, when it did it lasted for a couple of minutes then died now due to taking the spark plug in and out ive rounded the spark plug hole off.but ive got two spare 23cc cy engines one in bits and the other 1 built, my question is will the head of the cy engine fit ok and if it does will i lose power with it bieng of a 23cc thanx

23cc will rev quicker than the 26cc,but the 26 will have more torque and top end(slightly)
Answer to your question is ,yes,the head will fit on the bottom end but you will have to replace the piston and ring.If you are going to use a Zenoah head on a CY bottom end you will also have to replace the pin washers too and vice-versa.

You will need the piston that fits the head. The diameter of the piston is the size of the motor

23cc Head will need a 23cc piston (32mm)
26cc Head will need a 26cc piston (34mm)

The lower half (case) are the same from a 23 to a 26.

You'll need these as well. You cant use the CY washers on a Zen crank.
