I'm reading a great stuff about high compression...etc.
They say that you can diminish the squish clearance down to 0.0125 times the stroke. Cool. That's valuable info for a head shaving...but how do I measure the squish clearance? Or anyone know the stock squish clearance of a shee?

Thanks.

 

put a light coat of oil on the piston and head,place a piece of modeling clay on the piston,put the head back on with gasket and turn the engine over. remove the head a cut the clay down the middle and measure the thickness with a mic

 

Isn't this gonna change if the engine is cold/hot ?

 

all parts grow when hot so it should not change very much,.001/.003 at the most.
