Key Features & Qualities
-
Holy Grail 64mm Standard Bore: This is the BIGGEST selling point of this setup. These cylinders are measuring a true 64mm, meaning they are the original factory bore and have never been oversized, ported, or hogged out. With a standard bore, you have maximum material left for future rebuilds—giving you the ability to go to 64.25mm, 64.50mm, or 64.75mm down the road. The factory Nikasil plating is intact and presents well, offering a fresh starting point for a hone and new pistons/rings.
-
Genuine OEM Cylinders (Cilindros OEM): Authentic Yamaha castings with zero hack-job modifications. No welded repairs, no stripped stud holes, no cracked intake skirts, and no broken cooling fins. These are solid, straight, and true.
-
OEM Head (Tapa OEM): Includes the factory original cylinder head with stock domes. It has not been milled, shaved, or altered to run higher compression. This gives you the reliability of factory-spec squish and cooling.
-
Complete OEM Reed Valve Assemblies: Comes with the factory Yamaha reed cages and pedals. No broken reeds, and the rubber stops are in good shape. A perfect bolt-on setup for crisp throttle response.
-
OEM Intake Manifolds (Intakes OEM): Includes the original rubber intake boots that connect the reeds to the carburetors. They are pliable and free of dry-rot cracks, ready to seal up perfectly against your stock or aftermarket carbs.
Condition & Warranty / Disclaimer
-
Condition: Used / Pulled Complete: This assembly was removed from a running engine that was disassembled for a full chassis restoration. It has normal carbon buildup consistent with a well-used machine, but critically, there is no scoring, no deep gouges, and no seized piston damage on the cylinder walls.
-
What You See Is What You Get: We have not deglazed, blasted, or painted these parts. We are selling them in their honest, “as-pulled” mechanical condition so you can see exactly what you are working with. Please note, these will require a standard cleaning, fresh gaskets, and new pistons/rings to your preferred tolerance before installation.
-
Warranty: This top-end assembly is being sold “AS-IS” for the serious builder. We do, however, 100% guarantee that these cylinders are not cracked, not welded, and have no stripped head bolt threads. We back this up with a 14-day fitment/function guarantee—if there is a hidden structural flaw we missed, we will make it right. We do not cover wear items, assembly errors, or tuning issues once installed.
-
Shipping: We will professionally pack these heavy cylinders and components to ensure they arrive to your doorstep safely.
