BC3851 - Yamaha YXZ / Textron XX Stainless Steel Exhaust Valves - 27mm (+1mm)

BC valves are one piece design with a friction welded Stellite tip for the best possible performance.

The undercut stem above the head area not only reduces overall weight for extended rpm potential, but also significantly improves air/fuel flow in and out of the combustion chamber. Every valve is fully machined and features a swirl polished finish under the head.
