There may be other guys that disagree with me, but I say the japs that designed this bike are way smarter than most of us will ever be.
They are Brainy Smurfs for sure, but the issue is that (not being VW-Audi) they are constrained to comply with EPA regs regardless of the affect on driveability. Thus, their work can be improved by backing up the EPA chain a bit. California is worse than 48 state US is worse than Canadian spec. Main jets between Canada and 48US spec is the same and is correct. California mains are leaner.
