Ich Baue meinen Simson Cross Motor mit JW Sport Zylinderkit 85RM & LT85 EVO KW & Walzenlagern Part1

Today it's about the Simson engine for my Cross. I'm going to start building my engine with you. It's going to be a JW Sport 85cc cylinder. I'll show you how I build the engine and give you tips on how I personally build the engine and what to look out for. A 28 Polini carburetor is going to be installed, along with a Ronge Motorsport primary drive and an RZT clutch. I've opted for a Langtuning 85 EVO crankshaft with roller bearings. The gearbox is from Ronge Motorsport and is extra reinforced. The roller bearings are extremely robust and durable. The wide rollers mean the bearings have an extremely high load-bearing capacity. The Pro Seal clutch lever features a double seal against the transmission (the first seal is a shaft seal located in a CNC-machined aluminum sealing plate, and the second seal is the standard O-ring located on the lever shaft). This prevents dirt, water, or fuel (from the carburetor overflow) from entering the transmission, which could damage the 6000 series ball bearing or contaminate the transmission fluid. Here's something about the JW Sport Cylinder Kit: 85RM stands for an 85cc racing cylinder with reed valve intake. Technical specifications: Italkit piston, hard-anodized with piston window, very durable. Malossi VL 17 reed valve with rubberized aluminum support. VL 17 reed valve housing. 360° rotatable intake manifold for carburetors with a 35mm connection diameter (PWK 24-30mm). 5-port flushing with secondary outlets. Sensibly maximized port areas without compromising durability. Italkit piston, hard-anodized with piston window, very durable. After port machining, the cylinder is angled, drilled, honed, flushed, and deburred. Bore size between 49.25 and 49.75 mm, allowing at least 5 resurfacing dimensions. The port and timing design is engineered for high utility and a wide range with minimal resonator hole. From street use to A race win is possible thanks to the excellent drivability. Good exhaust compatibility. Compatible with many common tuned exhausts, including those from other manufacturers. Performance depending on the add-on parts and tuning: 16-19 hp per wheel with a wide usable range. The crankshaft is a Langtuning LT85 EVO forged crankshaft. With our EVO crankshaft, we finally have a crankshaft that eliminates some design-related weak points. Langtuning deliberately omitted lower thrust washers from our crankshaft, enabling a more stable interference fit between the crankpin and crank web. At the same time, the crankpin bearing is supplied with 50% more oil mixture, making this crankshaft extremely torsionally rigid and very durable. Ideally suited for very powerful engines and extreme conditions. Facts Design based on Langtuning's extensive knowledge and experience Torsionally rigid / stable interference fit Forged piston rod webs Forged connecting rod Heavy-duty alloy Optimized balancing High-quality silver needle bearings Race-tested Tapered journals allow easy installation of the crankshaft bearings Finely ground journals for long-lasting shaft seals 85mm connecting rod length 44mm stroke Enjoy the video.
