Description:

The main jet meters fuel at larger throttle openings, so it governs how your engine runs from the midrange up to wide open. The correct size keeps the top end clean and crisp, while the wrong one leaves the bike rich and sluggish or lean and flat. Match the jet size to your setup, and if you are simply replacing worn jets, order the size stamped on your originals.

• Meters fuel at mid-to-full throttle
• Sets clean, crisp top-end running
• Match the size to your carb setup
