The Wildcat 240RS is a unique engine that stands out in the market. It offers the largest displacement in a small block, combined with the best initial upgrades used throughout the industry. This means you get a high-performance engine without the need for immediate part changes or teardowns. The Wildcat 240RS is designed to meet all your needs, from spec kart racing to highly modified racing to mild and wild minibikes. And the best part?
Displacement: The WC240RS is a small block engine with a ¾" OD output shaft that is 240cc. 240cc is the same size as the smallest "big block" that Honda makes, which means you get big block displacement from a small block engine. To achieve this displacement, the bore is 72mm like the Tillotson 225, 228, and 236cc engines, but the Wildcat has a 59mm stroke crankshaft, which is a first for a complete engine.
The Wildcat 240RS is built with high-performance components that set it apart from the rest. The 240RS features the Wildcat WC946 head, equipped with 31mm Intake and 25mm Exhaust stainless steel valves. These larger valves give the engine a lot more potential than the smaller valves used on other small blocks, ensuring top-notch performance and reliability.
Carburetor - The Knock-Off VM22 carburetors are easily one of the most popular carburetors for upgrading your Predator, Tillotson, or Wildcat engine. The WC22 is an updated version that has been expertly blueprinted and tuned. The carburetor has proven to be better than other brands' similar carburetors, as seen here with real dyno results.
Camshaft - The Wildcat 240RS comes with the Banzai 265 camshaft, which has set the standard for camshaft upgrades on your mini bike and kart engine builds. This camshaft is included in the engine, which means you have a great cam out of the box, and even better, you don't have to worry about clearancing to make it fit around the 59mm crankshaft. This upgrade can significantly enhance your engine's performance, giving you a competitive edge on the track.
Flywheel/Ignition Coil - We are using the lighter cast aluminum flywheel that is rated for 8500rpms of safety and performance. Instead of using a mechanical internal governor, the Wildcat 240RS is rev-limited by a 6100rpms coil like the Ghost 212.
Side Cover - The side cover is identical to the Ghost 212, which features an oil fill on the top cover. The oil fill on top makes it easier to access when adding engine oil. You can also use this as a spot to add a fitting for a pulse line for a fuel pump.
Top Plate/Fuel Pump - The engine is set up to be nearly turnkey by including a top plate and fuel pump. This setup is chosen to work best with the WC22 carburetor since the stock fuel tank is not elevated enough to work properly. It also makes it easier to install for racing go-karts. Those who have an elevated tank and plan to gravity feed the engine may need to bypass the pump for optimal tuning.
Soft Grip Pull Rope - While it's a minor detail, we wanted to include the best options for our engine. The pull rope handle is not cheap plastic but a sturdy soft-grip handle.
Break-in Oil - These engines have not been started, so to break in the engine, we include the Maxima Racing Oil Break-in oil with every engine. To break in the engine: The engine must have a load. Do not free rev the engine! If you have a tach, keep the rpms between 3500-5500rpms, and if this is on a mini bike or go-kart, you can run the engine like normal for 15-20mins. A practice session or two works well to break in the engine. Just keep the engine below the rev limiter during the break-in.
Specs:
- Displacement: 72mm Flat Top Piston x 59mm Stroke Crankshaft = 240.11cc
- Cylinder Head: Wildcat WC946 18cc Cylinder Head with 31/25 Stainless Valves, 26lbs and Billet Retainers
- Compression: Approximately 11:1 Recommend 91+ octane gasoline (non-ethanol if available)
- Carburetor: WC22 26mm slide carburetor with Short Port Matched Intake
- Camshaft: .265" Lift Camshaft
- Ignition Coil: 6100rpms Limited Coil (No Internal Governor)
- Other Parts: Reinforced Block, Cast Aluminum Flywheel(safer than cast iron), Cast Rod, Side cover with top side oil fill(can use pulse fitting or 280 PCV), Top Plate with Aluminum Fuel Pump
