A very high performing race exhaust with an especially broad and practically laid-out power delivery.
Where a four-stroke motor requires valves, camshaft, exhaust and a turbo, a two-stroke just requires a well designed exhaust. A few pieces of sheet-metal modelled to create a form that harmonises perfectly with the layout and size of the openings in the cylinders bore, known as transfer and exhaust ports. The design of the resonance chamber not only influences the removal of hot exhaust gases, but the pulse effect also affects the flow of fresh fuel mixture into the cylinder. On modern two-strokes this technology is the main reason for its superiority over the four-stroke motor.
As simple as the description may seem, the creation of a properly formed expansion chamber body is a science for itself. This is where the wheat is separated from the chaff. Really good exhaust fabricators are as rare as uncooked steak and often only maintain limited production runs, making their products usually expensive.
NORDSPEED, based near Bremen in northern Germany, enjoy an almost legendary reputation as far as the production of excellent race exhausts for vintage geared Vespa and Lambretta scooters is concerned.
and NORDSPEED have combined their efforts in this field and the result are exhaust systems with the most powerful design, coupled with modern features such as EGT and a lambda sensor connection possibility.
Technical Specifications of all by NORDSPEED exhaust systems :

O-ring flange, suitable for all common cylinders.

EGT connector.

Lambda sensor connector.

Flange plate allows the attachment of most common silencers.
Camaro:
The ‘Camaro’ produces good torque and convinces with an appreciable power-band coupled with a harmonic delivery. It can also provide an excellent maximum performance. Whether in an urban environment, commuting or even touring through the mountains, the predictable power characteristic and strong, even torque delivery make the Camaro hard to beat.
The Camaro shows its true potential when combined with the suitable peripheral components and porting. This involves a larger carburettor, a gas-flowed inlet port and a tuning cylinder with larger transfer ports.
To fully exploit its advantages the Camaro requires matching with a cylinder possessing suitable port timings
– Transfer port timing: 124
– 130

– Exhaust port timing: 186
– 194

– Blow down timing: 30
– 32

Conclusion:
The perfect exhaust system for a very strong road-tuned motor, providing increased torque delivery and a well balanced combination of a wider power-band and a higher maximum performance.

TIP: A well set up carburettor and ignition are essential for a reliable motor. Tools such as a strobe lamp (#FS118600) and a degree disc (#83002000) are available in the shop. The jets for the carburettor set up should be from the same reputable manufacturer, as numerous producers work with different manufacturing tolerances. We recommend the purchase of a jetting kit from either or KMT.
