Hi PJ and welcome to the site.
I flipped through the front section of the factory service manual for '09's and
the Aussie model is different but only slightly. The same basic mods will apply
to your motorcycle and should give you the maximum power available from a
stock engine. These bikes are by no means powerhouses but they have some
serious pull in the first few gears.
The .22 mod is explained fully in this and the tech sections. In a nutshell shorty version
your fuel metering needle will be raised .026"-.052" (inches american) to richen the fuel
mixture slightly throughout most of the midrange rpms giving better throttle response and
a little more power that has been restricted away to meet clean air laws.
All models show 30 ft lbs torque (40 N-m/ 4.1 kgfm). That won't change and is more than plenty.
The airflow and fuel flow mods are for midrange and top end performance and easier
breathing at higher rpms.
Oh yes. The doohickey issue is resolved as far as breakage. You are safe. The spring is way too
long for little if any adjustment though and needs upgraded unfortunately. Usually most of us have
done it or had it done in the first 5,000 mi /8,000 km or less to be safe.
