porting?

[89blaster89]

does porting affect jetting? i always thought it didint? i have a head mod and that doesent affect jetting right? also does the bore size affect jetting? im confused now...

Seriously??? lol Every mod you do should require a plug chop to confirm jetting.That means porting,head mods etc. However going up one bore size will not affect it very much.

Porting should need a larger jet because it increases air flow. There's no increase in air flow with a redesigned head or increase in bore size. A larger bore increases volume but not air flow so your using the same air/fuel ratio .

On fitting a toroidial rechambered head I needed to decrease the size of the main jet by one size and drop the needle one slot.

Whatever you do confirm it with a plug chop.

That guy is talking out of the top of his head.

I run a wwholden head and it runs just fine on plain old pump gas.
