Zenoah has tightend up their squish clearance from what I have seen. You used to be able to drop the gasket all together, or just drop in a 1mm stroker crank because the squish was about .035-.040". The last G260 I measured a couple of months ago was .017". The smart thing to do is measure your stock vert squish clearance yourself. I have run as low as .010" squish, but I don't recommend it. .015 is about as tight as I would go. The stock Zen I last measured will not take the gasket swap you want to do.

So how do you measure the squish without a gasket ? a depth mic ? and then figure out from there ?
