The Short Carburetor Modification will increase throttle response, increase power from bottom-to-top with
more over rev and choke removal.
Having your carburetor bored will improve mid-to-top power and is available for the KX85/100 and CRF150R
The stock governor spring on the Kawasaki KX85/100 is too stiff causing the valve to open too late, which
results in a dip in the horsepower curve. The Governor Spring allows the valve to open at the right time,
eliminating the dip in the horsepower curve and resulting in improved bottom-end.
The Pro Circuit Power Valve for the KX85/100 lowers the exhaust port height to where it should be, resulting
in gains in the bottom-end while maintaining horsepower. This power valve combined with the governor
spring will provide a major improvement over the stock set up.
Pro Circuit’s Adjustable Power Valve for the KTM 65 SX allows the tuner to adjust the horsepower curve. You
can also use the pre-set setting that it comes with.
