Need some pics of porting jobs

[ltracer250r]

Alright i need some pics of some ported and polished heads and they need to be some good picture so you can see the details, im just trying to explain to someone what it means and they still dont understand.

you only port and polish heads for 4 pokes. 2 stroke you port the cyl and intake. look at macdizzy. they have pics of prtwork there

[lt250racer]

why do you only polihs the heads on 4-pkers and not 2 srtokes?

its because 2 strokes do not have valves well... we do have reed valves and power valves but thats defferent

[PA_Banshee]

Like solomx said you only do that to the paths the fuel/air mixture flows into and the exhaust gases flow out of. A 4 stroke comes through the head (assuming overhead valves) while the 2 stroke typically comes through the side ports. That's where you do the polishing and porting.

just tell him that you take metal out of the ports to make them flow more if they don'tunderstand that then
