Results:
Great torquey power which will happily lug just at idle all day and then respond crisply when required. Nice meaty hit of mid-range power which builds and revs nicely into a smooth top end. The transition into the mid-range is pretty abrupt and can make technical trails and hills interesting. This jetting was rich throughout the circuits once the needle got on the taper and it showed in the fuel economy.
