“for competition only! Not allowed in the German StVZO area! A very high performance racing exhaust with a particularly wide and practical power delivery. Where a four-stroke engine requires valves, camshaft, exhaust and a turbo, a two-stroke only requires a well-designed exhaust. A few pieces of sheet metal molded to create a shape that harmonizes perfectly with the layout and size of the openings in the cylindrical cylinder, known as transfer and exhaust ports. The resonance chamber design not only affects the removal of hot exhaust gases, but the pulse effect also affects the flow of fresh fuel mixture into the cylinder. On modern two-stroke this technology is the main reason for its superiority over the four-stroke engine. As simple as the description may seem, creating a properly formed expansion chamber body is a science in itself. This is where the grain is separated from the straw. Really good exhaust makers are as rare as raw steak and often only keep limited runs, making their products usually expensive. NORDSPEED, headquartered in Bremen, Northern Germany, enjoys an almost legendary reputation for producing excellent racing exhausts for vintage Vespa and Lambretta scooters. SIP and NORDSPEED have combined their efforts in this field and the result is exhaust systems with the most powerful design, combined with modern features such as EGT and a possibility of connecting the lambda sensor. Technical specifications of all SORD NORDSPEED exhaust systems: – O-ring flange, suitable for all common cylinders. – EGT connector. – Lambda sensor connector. – The flanged plate allows the attachment of the most common silencers. Camaro: The “Camaro” produces good torque and convinces with an appreciable power band coupled with harmonic delivery. It can also provide excellent maximum performance. Whether in an urban setting, commuting or even touring through the mountains, the predictable power characteristics and delivery of even strong torque make the Camaro hard to beat. The Camaro shows its true potential when combined with the right peripheral components and porting. This involves a larger carburetor, a gas flow inlet port, and a tuning cylinder with larger transfer ports. To take full advantage of its advantages, the Camaro requires pairing with a cylinder possessing adequate port times – Transfer port timing: 124 ?? – 130 ?? – Discharge port timing: 186 ?? – 194 ?? – Delivery times shutdown: 30 ?? – 32 ?? Conclusion: The perfect exhaust system for a very powerful road engine, offering greater torque delivery and a well-balanced combination of a wider power range and higher performance. TIP: A well set carburetor and ignition are essential for a reliable engine. Tools such as a strobe lamp (# FS118600) and a degree disc (# 83002000) are available in the SIP shop. The jets for carburetor installation should come from the same reputable manufacturer, as many manufacturers work with different manufacturing tolerances. We recommend purchasing a jet kit from SIP or KMT. “
