bowl to the carburetor body.)
5. Remove the main jet extender, (see figure #2).
6. Install the Power Tube, for ease of installation; turn the throttle

PLEASE READ THIS!!!!!!!!!!!!!!!!!
7. Install one of the supplied main jets. Which jet to use depends on your individual bike. The
choice will be made considering such things as exhaust, cams, and other high performance additions
your bike may have. Note: the main jets in this kit are interchangeable with stock H-D CV main
jets and can be purchased at any OEM or any aftermarket H-D dealer. However, they are not
interchangeable with Mikuni jets, the jet threads are different, even though the actual size of
the jets are the same, IE; if you have a 175 Mikuni main jet installed originally, then use the
supplied 175 main jet in this kit.
8. Reassemble the carburetor.
