Yamaha YXZ1000R / Textron Wildcat XX Valves
BC valves are one piece design with a friction welded Stellite tip for the best possible performance. Every valve is made from premium grade, heat resistant stainless steel 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. |

YAMAHA YXZ / 998 SERIES CAM BUCKETS (SHIM UNDER)
Due to Yamaha's notorious bucket wear, BC only offers cam buckets in DLC coating. Features "shim in bucket" design that requires BC0950B valve spring/retainer kit. Made from aerospace grade, 4140 chromoly steel alloy and completely CNC machined from heat-treated billet round bar. Heavy-duty wall thickness eliminates distortion and cam face depression, while reducing overall weight from non-critical stress areas. Nitrided and polished to a surface hardness of 60RC for minimal wear. Provides lower friction with cam lobes and cylinder head lifter bores for improved durability. |
