17 mm racing carburetor for Sachs 503 2 AL/BL, ABL, AAL, AB, AC, ADV or Puch X30 Velux, as well as other mopeds / mopeds which are originally fitted with a Bing SRE carburetor and have the idle throttle screw on the right-hand side of the carburetor (in the direction of travel).
World first: The tuning carburetor consists of the slide tower of the SRF 17 mm carburetor and the base of the SRE carburetor. This achieves a passage of 17 mm with an almost original appearance. A special intake manifold with a 23 mm connection diameter is required.
For perfect camouflage, the tuning carburetor is provided with the original number «1/12/327». This means that the carburetor is practically indistinguishable from the original when fitted.
Attention: If the original Velux air filter is used, the right-hand side protection must be slightly underlaid. If the air filter box is to be used with the Sachs 503, it must be carefully drilled out.
