Moose Racing Stainless Steel Exhaust Valve Kit for Yamaha YZ WR 250 F M80-80860

  

This item fits the following models. Each kit includes stainless steel valves, High-Rev valve springs, steel retainers, and Viton valve seals.

Stainless steel valves are made from a one-piece forging out of 21-4N stainless steel. Valves go through a black nitrided hardening treatment which decreases valve wear and improves performance. High-Rev springs are heat-treated and stress-relieved, which dramatically increases the springs' life cycle. Valve seals are made with Viton rubber which allows for greater seal and less stiction. We must be notified within 24 hours of receipt of any missing, defective or damaged goods.

Any item which has been used, worn, damaged or had tags/labels removed will not be eligible for return. Any damage claims may be exchanged for the identical item only.
