ordered a 14cc head ;)

[justinkk2005]

Current mods:
flat top piston
billet rod
18 lbs springs
mikuni 22 mm carb


the 14cc head make a big difference on the gx200? I'll have to run 93 wont i

comp ratio with flat top is like 11:8:1

18cc has more flow... but it's a tradeoff.

Flywheel next.

some say it flows the same..

Good info out there on other forums.

bobs 4 cycle, minibike forum ect ect ect

4cycle said that... lol... and seeing as they weld up/mill their own heads, and the actually port the combustion chamber... I'm inclined to think they know what they're doing...

Actually I think they might've flow bench'd it... me no remember

most of the guys at 4 cycle actually weld up the 18cc heads, achieve similar combustion, and still have the needed port velocity. its not really a trade off this way, but. You're 14cc head will make a diff in power and sound. My engine is 13.5:1 comp and needs 110. it sounds like a popcorn machine.

I think youwill see no difference between shaved 18cc and a 14cc (stock) on your cart

the stock carb flows less then both heads anyways

14cc add larger stainless intake valves and unshroud them you will have a NICE head for a BAD@SS motor.. your mikuni should do fine on both.
