WISECO - VES028 - Exhaust Valve - Yamaha YFM350/YFM400
Valve geometry and material quality are what determine how cleanly your engine breathes, seals at the seat, and delivers compression across the rpm range. The WISECO VES028 is machined to OEM dimensional specifications for Yamaha YFM350/YFM400 engines, giving you a replacement that maintains the seat geometry and stem tolerances your engine was designed around. Treated with either CVD or CNI (depending on the application), both applications are wear- and friction-reducers that resist heat penetration as well. Application: Exhaust. A precise, properly fitted valve is one of the most fundamental components in a reliable engine, and the VES028 gives you exactly that.
