Does anyone know the manufacturer's specified volume for the combustion chamber? I've measured mine (all 4 49.5 +0.5cc) with valves and spark plugs installed, and I'm wondering how much volume I put in there when I reshaped the chambers. Also, is their volume with or without the head gasket height (I measured to the bottom of the head only)? I searched here and at HA, as well as hyundaitechinfo.com with no luck.

How many ccs in the combustion chamber? Anyone? Bueller?

 

combustion chamber volume is only the chamber, no gasket
(only valves, and spark plus installed)

mine cc'ed at 47 cc but i did polish them a bit, and cleaned the lips where they blen in the seats

 

^ Thanks for that.

hmmmm.... You wouldn't happen to have a clean stock head up there would you?

I know shavings don't pack very tightly when you sweep them in a pile, but it would be quite a surprise to find out I had "only" taken out 2.5cc from each chamber!

 

At one point, Random (Tony) had his cc'd out when stock, and I used his figures for calculating the compression for the piston dishes and deck clearance when I did my motor eons ago. 47cc sounds 'about right', but it's been too long ago to say for sure. I was pretty positive that information made it to HA in one form or another, but quite a bit of searching has yielded nothing thus far.

Edit - I sukc at teh spelinng

 

i havea few stock heads, if i get enough "free" time i'll try to cc one for you

 

Haha, you w/ free time that's a good one!
