Part: Honda CL450 / CB450 / CB500T Main Jet Tuning Kit
Why You Need This: Did you swap out the intake or exhaust on your bike, and now you're noticing it's not pulling hard to red-line? Do you live at a high elevation? It sounds like your carbs need a re-jet. Every parts combo and engine is different, which means you must tune the bike to where it runs best. While this can be a tedious process, we're here to ease the pain. Our Honda CL450 / CB450 / CB500T main jet tuning kit comes with jets in increments of 5. The carburetor rebuild kit comes with a #130. We fill in the gaps with jets sized: 120, 125, 130, 135, 140, 145, 150, 155, 160. One kit will tune both carbs. If you are running a Pod Filter like ours, then this kit is highly recommended.
Installation Tip: Use the right sized screw driver to fit the jets, they are soft brass and damage easily. Start your tuning with a fresh set of spark plugs so that you can read their color. Use the factory size jets first and move up or down from there. BTW no jetting change will help a less than spotless carburetor.
