BIG and Hi COmp...:P

how much levey ,do you have new valves for it ?

Valves are good, name your price.

Hey Levey,

My head needs re-work but it also needs a fat gasket to bring the comp-ratio down. So it basically needs more money thrown at it.

I'm interested in this one but not certain, I have a low comp head on the way to me to try but I would prefer high compression.

Any chance you could tell me how big the chambers are in cc's?

Is the rocker gear included? Springs singles or doubles?

To get the cc's I use a cheap CD case covers with a small drilled hole and 10ML syringe to inject oil, simply count the cc's until you can see the chambers are full of oil (any oil is good).

You may need to seal around the chambers with some coloured (marine?) grease just to make it easy to see when it is full and to make sure no oil leaks out.

I think I need 21cc+ chambers to put me back onto pump fuel.

EDIT: Oh, could you also confirm if the ports are standard or larger?

Combustion chamber is 25cc stock.

I CC'd it a while ago but cant remember the result, will do it again.

I remember now, I got 27.5cc last time and the same reading on a H75 head. This time 28cc, are you sure about the 25cc DD? this head has been resurfaced aswell.
Oh and I used water not oil.
Ports:
Inlet: 33x40mm
Ex: 22x29mm

EDIT: Comes with single springs and rocker gear.
