Burris Racing Briggs Raptor 0.020" Oversize Scraper Ring - BSR020R3 - Flathead Rebuilds

Every fraction of horsepower counts when you are building a championship-winning racing kart, and oil drag is the silent killer of top-end speed. The Burris Racing 0.020" Oversize Scraper Ring (MPN: BSR020R3) is engineered specifically for Briggs Raptor flathead engines that have been bored over, delivering meticulous oil wall clearance without sacrificing cylinder lubrication. When you are pushing your equipment to the absolute limit, this scraper ring ensures your engine runs lean, mean, and ready for the podium.

Precision Oil Control for Your Racing Kart Engine

Unlike standard rebuild components you might find on a generic go kart engine for sale, this Burris Racing scraper ring is purpose-built for high-RPM abuse. By effectively organizing oil flow and reducing parasitic drag against the cylinder wall, it frees up critical horsepower. Lower wall tension means less friction, translating directly to higher RPMs and extended cylinder life. Whether you are dialing in your chassis with the best go kart tires for racing or upgrading your safety gear with premium go kart helmets, your engine's internal efficiency is what ultimately dictates your straightaway speed.

Flathead Reliability vs. Briggs LO206 HP

While the modern grid is heavily populated by the briggs and stratton 206 engine, the classic Raptor flathead remains a powerhouse in modified and open classes. Achieving maximum output from a flathead requires precision machining and oversized internals. While racers focus on maximizing their briggs lo206 hp through tuning, flathead builders rely on oversized components like this 0.020" scraper ring to restore compression and eliminate blow-by in worn or freshly machined steel-sleeved blocks. It is the ultimate reliability upgrade for aggressive driving styles.

Technical Specifications & Features

Frequently Asked Questions

Q: How do I know if I need the 0.020" oversize scraper ring?

A: This ring is designed for Briggs Raptor flathead engines that have been bored 0.020" over standard size. You should verify your cylinder bore diameter with a precision bore gauge before ordering to ensure this ring provides the correct clearance for your specific engine build.

Q: Does this scraper ring require a specific break-in procedure?

A: Yes. Like all high-performance piston rings, it is recommended to follow a proper heat-cycle break-in process. This allows the ring to seat correctly against the cylinder wall, ensuring optimal compression and oil control for your next race.

Q: Can I use this ring on a standard-bore Briggs Raptor engine?

A: No. This ring is specifically sized for a 0.020" over-bored cylinder. Installing an oversized ring into a standard-bore cylinder will result in improper end-gap, which can cause the ring to bind, damage the cylinder wall, or lead to catastrophic engine failure.

Q: How does a scraper ring differ from a standard compression ring?

A: While compression rings are designed primarily to seal combustion gases, the scraper ring is engineered to manage oil film on the cylinder wall. It scrapes excess oil back into the crankcase, preventing it from entering the combustion chamber, which reduces carbon buildup and minimizes parasitic drag.
