Yamaha Blaster Performance Cylinder Head – High Compression

Description

Yamaha Blaster Performance Cylinder Head- High Compression

Increase the power and performance of your Yamaha YFS200 Blaster with a professionally modified cylinder head from Ken OConnor Racing. This performance head features a reshaped combustion chamber designed to improve compression, combustion efficiency and overall engine output.

Depending on your engine combination and supporting modifications, this cylinder-head upgrade can add approximately 3–5 horsepower. It is an excellent addition to ported cylinders, aftermarket exhaust systems and other performance-oriented Yamaha Blaster builds.

Unlike a generic replacement head, this cylinder head is professionally machined for Yamaha Blaster performance applications by an experienced two-stroke engine machine shop.

Fuel requirement

This is a performance cylinder head that increases engine compression. Always use fresh premium high-octane gasoline. Fuel requirements can vary depending on compression, port timing, ignition timing, elevation and the rest of the engine combination.

Proper carburetor jetting and a leak-free engine are required. Check piston-to-head and squish clearance during assembly, especially on stroker, decked or otherwise modified engines.

Important note
