Red Line 20W-50 Powersport Motor Oil V‑Twin Powerpack Kit — 5 qt engine oil, transmission & primary care

Red Line 90226 Powerpack is a complete 20W‑50 motorcycle service kit built to refill V‑Twin, Twin‑Cam, Milwaukee‑Eight and Evolution engines with high‑performance 20W‑50 oil plus transmission, primary and fuel system care.

This all‑in‑one kit supplies the core lubricants and cleaners needed for a full oil service on many Harley‑style motorcycles. It bundles five quarts of 20W‑50 motorcycle oil together with V‑Twin transmission oil (with ShockProof friction modifier), primary chain case oil, a fuel‑injection cleaner formulated for powersports, a funnel, a sticker set and a Red Line embroidered hat—everything packaged to streamline maintenance while using Red Line’s long‑established formulations.

Which engines and models does this kit work with?

This Powerpack targets American V‑Twin platforms and is compatible with many Evolution, Twin‑Cam and Milwaukee‑Eight engines from model year 2007 onward. It covers the common wet capacities found in Milwaukee‑Eight and many V‑Twin primary cases, though some large Twin‑Cam engines require an extra bottle of primary oil to reach full capacity.

• Covers 2007+ Harley‑style bikes with 96 cu in and larger Twin‑Cam engines (note extra primary oil may be needed)
• Supplies enough 20W‑50 oil for standard oil changes on most V‑Twin crankcases
• Includes transmission and primary oils matched to V‑Twin specifications

What exactly is included in the kit and how much of each fluid?

The kit is assembled so you can perform a thorough service without sourcing individual bottles. Quantities are set to fit typical V‑Twin service intervals and to simplify parts stocking at home or in a small shop.

• 5 quarts of Red Line 20W‑50 motorcycle oil for the engine
• 1 quart of V‑Twin transmission oil with ShockProof additive
• 1 quart of primary chain case oil
• 1 bottle of Red Line Fuel Injection Cleaner for powersports
• Includes funnel, sticker set and embroidered Red Line hat

Will this kit complete a full service or are extras required?

For most Milwaukee‑Eight, Evolution and many V‑Twin bikes the kit contains sufficient oil volumes to execute a complete oil and fluid service. Be aware that some larger Twin‑Cam cases have larger primary capacities; in those cases you’ll need one additional bottle of primary chain case oil to fill to spec.

• Tested for compatibility with common V‑Twin wet capacities
• Buy one extra primary oil bottle where engine spec lists 38 oz (45 oz dry) capacity
• Always verify your motorcycle’s exact fluid capacities before starting service

Who this kit is for: Mechanics, DIY motorcycle owners and small shops that service Harley‑style V‑Twin bikes and want a single, branded package of high‑viscosity 20W‑50 engine oil plus the matched transmission and primary oils. It’s aimed at riders who prefer established, race‑proven lubrication brands and want to simplify routine maintenance with a ready‑to‑use set. If your model’s primary oil capacity exceeds the kit’s included quart, plan to add one extra bottle of primary chain case oil to meet the manufacturer’s fill specification.
