Red Line Powersports Fuel System Cleaner, 4 oz Two-Pack — concentrated treatment for injectors, valves and combustion chambers

Red Line 60102 Complete Powersports Fuel System Cleaner is a concentrated 4-ounce treatment (sold as a two-pack) designed to clean fuel injectors, intake valves, and combustion chambers on motorcycles, ATVs, PWC and small engines.

Formulated for powersports machines, this compact fuel system cleaner targets gum, varnish and carbon deposits that accumulate from ethanol blends and high-performance operation. It works with pump gas, race fuel and pre-mixed two-stroke fuels, making it a flexible option for street bikes, dirt bikes, quads, and personal watercraft. Each 4-ounce bottle treats a fuel tank for a thorough, quick clean-up without overfilling or diluting beyond effective strength.

How does this cleaner restore performance?

The formula reduces octane demand and removes deposit build-up that can rob power and throttle response. By cleaning intake valves and combustion chambers and lubricating the upper cylinder, it helps the engine run more efficiently and consistently under load.

• Breaks down gum and varnish on injectors and carburetor jets
• Removes carbon from combustion chambers and valve faces
• Lubricates upper cylinder to reduce friction and wear
• Helps recover lost power and improve throttle response

Will it work with my fuel type and engine?

This cleaner is compatible with a wide range of fuels and engine formats common to powersports. It treats both pump and race gasoline and can be used in pre-mixed or injected two-stroke systems without changing fuel chemistry.

• Safe for fuel-injected and carbureted systems
• Works with ethanol-blended pump gas and high-octane race fuel
• Suitable for pre-mixed and injected two-stroke engines
• Designed for motorcycles, dirt bikes, ATVs, quads and PWCs

How do I use a 4-ounce bottle correctly?

Pour one 4-ounce bottle into a near-empty fuel tank or add at the gas pump before filling for good mixing. Run the engine through normal operating ranges or take a short ride to allow the cleaner to circulate, dissolve deposits, and be consumed with the fuel.

• Use one bottle per tank for typical powersports fuel tanks
• Pour into tank before refueling to ensure proper mixing
• Ride through varied throttle ranges for best circulation
• Repeat treatment if heavy deposits are suspected

What benefits can I expect after treatment?

After treatment, many users notice improved throttle response, more consistent idle, and a smoother power delivery — especially if deposits were restricting flow. While results vary with engine condition, regular use helps maintain cleaner fuel pathways and reduces octane demand caused by deposits.

• Improved throttle response and quicker revving
• Smoother idle and reduced hesitations under load
• Potential fuel economy improvements when deposits are cleared
• Helps preserve fuel system components over time

Who is this for: Red Line 60102 is aimed at riders and owners of powersports machines who want a compact, concentrated fuel system treatment. It's a practical choice for enthusiasts who service their own bikes, racers prepping machines between events, and anyone facing performance issues tied to fuel deposit buildup. The two-pack format gives two treatments for routine maintenance or back-to-back cleaning sessions.
