Cometic one-piece fiber base gasket, intake gaskets, and cool head O-ring kit. Port Timing Is Critical - Don't Skip It. This 421cc setup must be ported properly.
These cylinders are dune/play ported by design, however, the port timing is made for a 392cc/400cc configuration. Slapping in a thick base gasket is NOT a real fix and WILL rob your Banshee of its true potential! Correct port timing to match 421cc stroke. Use BPRATV's in-house porting service for maximum performance.When it comes to building a high-performance Yamaha Banshee, Nikasil (nickel-silicon carbide plating) is a game-changer. Transfers heat more efficiently, keeping your motor cooler. Provides a harder, smoother piston surface, reducing friction.
Lasts longer between rebuilds thanks to durability. Lightweight aluminum design for stronger performance. Athena vs CPI Cub vs BPRATV ARES.Athena and CPI Cub cylinders have long been the benchmark for Banshee builds. Athena delivers strength at a higher price, while CPI Cubs are known for raw performance and Nikasil durability. The BPRATV ARES cylinder bridges the gap-offering Athena-level performance at a fraction of the cost!
