Red Line Powersports Fuel System Cleaner 4 oz — 2-Pack Concentrated Treatment for Motorcycles & ATVs

Red Line 60102 Complete Powersports Fuel System Cleaner is a concentrated 4-ounce treatment (sold as a two-pack) designed to remove fuel-system deposits and restore throttle response in motorcycles, ATVs, PWC and other powersports machines.

This compact, professional-grade formula targets varnish and carbon buildup in intake ports, combustion chambers and on intake valves while lubricating the upper cylinder area. It’s formulated for modern and older engines and works with both pump and race fuels, including pre-mixed or injected two-stroke applications. Each 4-ounce bottle treats a full tank, making the twin-pack convenient for repeat maintenance or two machines.

How does this cleaner help systems that feel sluggish?

The formula reduces octane demand and strips deposits that rob power and throttle sharpness. By dissolving varnish and carbon, airflow and combustion return closer to design specifications, improving responsiveness without engine disassembly.

• Restores more complete combustion by clearing combustion-chamber deposits
• Removes intake-valve and port varnish that disturbs airflow
• Lubricates the upper cylinder area to reduce friction during operation

Will it work in my two-stroke or injected engine?

Yes — the cleaner is compatible with pre-mixed two-stroke fuel and with fuel-injected two-stroke systems as well as four-stroke engines. It’s safe to use across a wide range of fuels and common powersports equipment when used as directed.

• Safe for pre-mix and injected two-stroke applications
• Compatible with pump gas and high-performance race fuels
• Single 4-oz dose correct for a full tank on most motorcycles, ATVs and PWCs

How do I use each 4-ounce bottle for best results?

Pour one 4-ounce bottle directly into a full fuel tank before riding for routine maintenance or after fuel sits long-term. For heavier buildup, follow up with a second treatment at the next fill or consult service guidance for more aggressive cleaning.

• Pour entire bottle into a full tank for one-treatment maintenance
• Run the engine to circulate cleaner through intake and combustion areas
• Repeat on the next fill if heavy deposits are suspected

What can I expect after treatment?

Typical benefits include improved throttle response, reduced hesitation, and a return toward original power delivery as deposits are removed. Results vary with engine condition, but most users notice a cleaner idle and crisper acceleration after treatment.

• Reduced hesitation and smoother throttle transitions
• Improved fuel economy potential by lowering octane demand
• Cleaner combustion chamber and intake surfaces for consistent performance

Who is this for: Riders, racers, and powersports technicians who maintain street bikes, dirt bikes, ATVs, side-by-sides and personal watercraft will find this product useful. It’s suited to owners who want a compact, professional-strength maintenance treatment that’s easy to store and simple to apply. Use the two-pack to treat two machines or to perform a follow-up treatment after heavy use or long storage intervals.
