Overview

The Boyesen RB-18A is a replacement carburetor boot designed for 600cc snowmobiles, specifically noted for the 2014 Ski-Doo MXZ Sport 600 REV XP. This component is part of Boyesen's Rage Cage system and features a dual-stage reed design, which aims to provide more usable power and improved performance across the entire RPM range compared to stock single-stage reeds. The dual-stage design combines a soft top reed for crisp throttle response and a firmer, ported bottom reed for maximum flow and horsepower at higher RPMs. The T2 epoxy construction includes toughening additives to enhance reed petal lifespan against fuel-related breakdown. This part is compatible with various Boyesen Rage Cage assemblies including RAD81A-2, RAD83F-2, RAD84-2, RAD84-KIT, RAD85F-2, and RAD85F-KIT.
