hi, in a previous post i asked if it was possible to low comp my standard pistons.
lots of people have said it is ok.
but how much needs to be machined/skimmed off the top?
is it as simple as that?
hope you can help cheers.

 

you can take off up to 1mm but you need to work out what comp ratio you wont to run

 

no need to go low comp unless your going over 22psi or is will just lose you power
