The problem is that this system works only as a pre‑break‑in, and the engine still requires an on‑track break‑in.\u003c\/p\u003e\n\u003cp\u003eAt Ultimate Racing, we wanted to go one step further and offer our customers the possibility of purchasing engines that are fully broken‑in and ready to race with no additional break‑in required. In other words, engines that can be used in the most demanding competitions exactly as you receive them, straight out of the box.\u003c\/p\u003e\n\u003cp\u003eTo guarantee quality and ensure that all “Team Edition” engines are broken‑in to the exact same standard, we have developed a fully monitored break‑in bench that controls temperature, RPM, and break‑in time at all times. The entire break‑in process is performed with the engine perfectly lubricated to minimize load and wear on all components, significantly increasing its lifespan.\u003c\/p\u003e\n\u003cp\u003eDuring each phase of the break‑in, the engine’s resistance torque is also monitored, allowing us to determine the precise moment when the break‑in should be completed. This guarantees that all our “Team Edition” engines are perfectly broken‑in and ready to compete.\u003c\/p\u003e\n\u003cp\u003eOnce the break‑in is finished, the engines are disassembled, inspected piece by piece, and reassembled by our racing team, ensuring the highest product quality for our customers.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\u003cp\u003eIn addition to the modifications already included in the previous version—such as the crankshaft, backplate, cylinder\/piston set, the innovative 6 and 6.5 mm FlowMax venturi, and the crankcase designed to achieve greater power without compromising fuel consumption—\u003cstrong\u003ethe v3 incorporates a new, less sensitive high‑speed needle to make it easier to find the optimal carburetion setting.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWith this engine you will enjoy an incredible power curve that delivers outstanding usable power at all times.
