your posts have actually now given me some insight now into why my pressures on that motor reacted with increased RPM appropriately, but started to fall off shortly afterwards. all this time i thought it was the modifications i made to the e-shaft jets. now i'm thinking i might have simply blown out the front cover o-ring.
if i recall, that front regulator bypasses at 156 psi from the factory, it usually gets shimmed when you use the high pressure rear regulators.
