just inquiring, u sure that stk head gasket .85mm, all previous gens were .65mm. so deck height on ur motor only .005-.006? dont have experience with gen 5 but lots with previous gens. my std street 10 builds are .45mm hg and .015 head mill. run on pump gas no problems. my 07 has .45hg and head milled .028, does fine as long as ur moving but not a red light/stop and go traffic bike anymore. ur not gonna detonate or overheat at that suggested minimium squish on pump gas doing what u do. just surprised at those numbers. if correct going from close to .040 squish to less than .030, bike gonna really wake up everywhere in powerband. btw, tightening the squish helps prevent detonation.
