{"product_id":"tillotson-212r-reinforced-engine-block-bare-70mm-bore-modified-class","title":"Tillotson 212R Reinforced Engine Block (Bare) - 70mm Bore - Modified Class","description":"\u003cp\u003eBuilding a championship-winning racing go kart starts with a foundation that won't crack under extreme compression, and the Tillotson 70mm reinforced block delivers exactly that. Engineered specifically for high-RPM applications, this bare block is the ultimate starting point for your 212cc or 196cc clone build. By utilizing a heavy-duty cast iron sleeve and thickened webbing in high-stress areas, it eliminates the flex and catastrophic failures commonly seen in standard clone or Predator blocks. When you are pushing the limits on the track, this rigid foundation ensures your crankshaft spins true, transferring maximum power directly to the chain.\u003c\/p\u003e\u003ch2\u003eUnmatched Durability for Mini Go Karts and Racing Chassis\u003c\/h2\u003e\u003cp\u003eWhether you are building high-performance mini go karts or tuning a modified engine for national-level competition, structural integrity is non-negotiable. This block features enhanced gusseting and a premium casting design that dissipates heat efficiently, preventing power fade during long mains. It is fully compatible with standard clone internals, allowing builders to easily mix and match Tillotson heads with clone cranks. Note that it requires the JF168-1500 crankcase cover, as there is currently no OEM Tillotson alternative available separately.\u003c\/p\u003e\u003ch2\u003ePrecision Engineering for the Ultimate Build\u003c\/h2\u003e\u003cp\u003eTuning a race engine requires precision at every level—from dialing in your lo206 carburetor kit to ensuring your cylinder bore is perfectly matched to your piston. This block's superior machinability allows for custom over-bores, unlocking tailored torque curves that pull hard out of the corners. The built-in front tank mounts also make it versatile for \"stock appearing\" classes. Even if you are browsing adult go karts for sale, upgrading the powerplant with this reinforced block guarantees a night-and-day difference in reliability and brute speed. You'll feel the improved power delivery right through the steering wheel and chassis the moment you hit the throttle.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeavy-Duty Cast Iron Sleeve:\u003c\/strong\u003e Ensures long-lasting cylinder life under extreme heat and high-RPM racing conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickened Webbing \u0026amp; Gussets:\u003c\/strong\u003e Targets common failure points to prevent block cracking during high-compression strokes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e70mm Standard Bore:\u003c\/strong\u003e Ready for your choice of piston, rings, and custom displacement tuning.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClone Internal Compatibility:\u003c\/strong\u003e Easily accepts Honda GX200, Clone, or Predator crankshafts and camshafts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFront Tank Mounts Included:\u003c\/strong\u003e Perfect for builders competing in \"stock appearing\" racing classes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuperior Heat Dissipation:\u003c\/strong\u003e Keeps engine temperatures stable to prevent power fade during extended track sessions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRequires JF168-1500 Cover:\u003c\/strong\u003e Designed to mate perfectly with specific crankcase covers for a leak-free seal.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What crankcase cover do I need for this block?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e This block requires the JF168-1500 crankcase cover.
