Darn, i was tryin' to work it

What makes the 53 a better cylinder for the water cooled kit ? Is it design , different porting, or just a different quality.......?

I 'm looking for something to replace the 54mm and we're kinda torn between stroking it with another 54mm or going back to 52mm to allow wider class entry. Some of the local races here allow every mod except you can't violate the 90cc size. Other classes are 90-125cc anything goes.
Really wish we had more races in MIchigan that didn't require outta state or across state travel.Would luv to do it, just can't rght now.
