Cylinder Head Cover by Yamaha

Yamaha UTV/ATV & Side by Side Valve Cover - Available at buywitchdoctors.com

Product Specifications: Genuine OEM Yamaha Cylinder Head Cover, Part # 2S2-11190-21-00.

Keep your machine running like new with a genuine Yamaha Valve Cover paired with premium maintenance parts from buywitchdoctors.com. The valve cover seals the top of the cylinder head, keeping oil in and dirt, water, and debris out of the valvetrain while giving you access to the valves, rockers, and camshaft for inspection and adjustment. A solid, properly sealed cover helps maintain oil pressure and protects the moving parts underneath from contamination and premature wear. Riders most often replace a valve cover after oil leaks or seepage around the edges, cracks or dents from a rock strike or rollover, warped sealing surfaces, stripped or damaged bolt holes, stripped breather fittings, or corrosion and sun damage.

Why Choose Genuine OEM Yamaha Parts?

Choosing original equipment manufacturer (OEM) parts ensures your vehicle maintains its factory-standard performance, reliability, and fuel efficiency. Genuine parts eliminate the guesswork of aftermarket alternatives, offering a seamless integration with your engine's configuration.

• Exact-Fit Design: Matched to Yamaha's original bolt patterns, sealing surfaces, and dimensions for a leak-resistant fit.
• Factory-Spec Quality: Built to the same standards as the parts installed on your machine at the factory.
• Peace of Mind: Skip the trial and error of universal or aftermarket parts that may not seal or align correctly.

Premium Materials & Precision Engineering

Crafted to strict factory tolerances, these components utilize high-grade alloys and chemical-resistant seals. This specialized engineering withstands harsh off-road vibrations, extreme temperatures, and modern fuel additives, preventing premature wear and leaks. The valve cover is cast or molded from heat-resistant, oil-resistant material with a flat, precisely machined sealing surface and accurately placed bolt holes, so it seals evenly against the cylinder head and holds up to engine heat cycles and vibration.

Other Popular Parts & Secondary Accessories

• Valves & Springs: Valves and springs control the flow of air and exhaust in and out of the cylinder, and worn parts can hurt power and idle quality. Since the valve cover is off for inspection, it is a great time to check them and catch problems early.
• Top End Gaskets: Top end gaskets seal the cylinder head and related surfaces and are typically replaced whenever the top end is opened. Pairing a fresh set with your new valve cover helps ensure proper sealing and easier reassembly.
• Engine Gaskets & Oil Seals: Engine gaskets and oil seals keep oil, coolant, and pressure where they belong. Replacing them while you are working on the valve cover helps prevent leaks and lets your repair start clean.
• Complete Gasket Kits: A complete gasket kit bundles the seals you need for a full engine or top end service in one package. Choosing one with your valve cover saves time and helps make sure you have every gasket on hand before you start.
• Gasket Maker & Epoxy: Gasket maker and epoxy help seal tricky joints and repair small cracks or stripped areas when used as directed. Check your Yamaha service manual to see where sealant is called for so you use it only where it belongs.
• Gasket Scraper Tools: Gasket scraper tools help you remove old gasket material and residue without gouging the sealing surface. A clean, smooth mating surface is the key to a leak-free fit with your new valve cover.

Frequently Asked Questions (FAQs)

Q: How do I know when my Yamaha valve cover needs to be replaced, and how do I confirm the right one for my machine?
A: Look for oil seeping around the edges, cracks or dents, a warped or damaged sealing surface, stripped or broken bolt holes, and damaged breather or hose fittings. Before replacing it, inspect the gasket, the cylinder head surface, and the bolts, since a bad gasket or damaged threads can cause leaks even with a good cover. Because valve covers vary by model, model year, engine, and trim, confirm the correct part, gasket, and installation procedure using your Yamaha service manual or factory schematic, or contact us with your model and VIN and we will help you match it.

Q: How do mud, water, sand, and heat affect a valve cover on the trail?
A: Mud, water, and sand can pack around the cover and its fasteners, trapping heat and speeding up corrosion, while constant engine heat cycles can harden gaskets and cause slow oil seepage. After a wet or dirty ride, rinse the area gently, avoid blasting water at seals and breather fittings, and check for oil seepage or loose bolts. Follow your Yamaha service manual for correct installation and sealing guidance so your valve cover stays leak-free.
