BC3853-N - Yamaha YXZ / Textron XX Inconel Exhaust Valves - 27mm (+1mm)

BC valves are one piece design with a friction welded Stellite tip for the best possible performance. Every valve is made from premium grade, extreme heat resistant Nimonic 90 alloy or Inconel material to insure reliability with high boost and/or high rpm applications. 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.
