But here is the questions:


How big can a 23cc be built to?


and how big can a 26cc be built to also?

I believe 30.5cc

the highest we can go is a 30.5. its a simple head and piston but with the large mills you also have to do the crank shaft. with the higher displacement comes less rpms, but a larger room for re-gearing and more chance of brokin driveline parts

so this is why everyone goes with the 28.5cc headkit. I see the light now.

 

[kryptonite5b]

ya the 2 biggest things you can do for power and speed are the pipe and headkit. alot of people do the pipe first, where i ALWAY do the head first. plusits cheaper. a good headkit cost $75.00

Stroke stock is 28mm +1=29mm +2=30mm


piston's come in 34mm 35mm and 36mm, that is all there is to work with.


26cc stock stroke of 28mm and a bore of 34mm


27.2cc +2mm stroke of 30mm and a bore of 34mm


28.5cc stock 28mm stroke and a bore of 36mm


Why people are sticking with the 28.5cc Short stroke means it revs up fast and the larger cylinder/piston makes alot more power.
