the only thing i can think of is that its rounded up. the cy 26 is really a 25.4 and the 27 is a 26.9. so im not really sure what the 28 is..

what are the numbers on the side of the top end?


If it has 28 36 its a 28mm bore and 36mm stroke 29.5cc. First number being stroke, 2nd being bore size.


I doubt it will be a 29-35
