43 mm racing cylinder with 63 cc, suitable for Sachs mopeds / mopeds with 503 2AL, AAL, 2BL, ABL CH engines.
Thanks to the additional holes for the cylinder head bolts and the two mounts for the blower cover, the cylinder can also be fitted to the Sachs 50/2 and 502 models, although the intake and exhaust accessories must be made by yourself.
The large displacement and the huge intake ensure plenty of torque.
The cylinder can be used on both Sachs 50/2 and Sachs 503 mopeds with the original cylinder head, but it should be noted that the pinch point at the narrowest point should be at least 1.5 mm. To ensure optimum operation and thus tease the maximum power out of the cylinder, we recommend adapting the cylinder head to a combustion chamber diameter of 43 mm. It is best to use the 41 mm cylinder head from the accessories as a basis for this.
We also recommend that you use reinforced clutch springs so that the entire engine power can be transferred to the rear wheel. You can find these in the accessories section.
The BADASS 17 mm or 15 mm intake manifold is the perfect match for the cylinder, with which either a 15 mm Bing SRE or a 17 mm carburettor can be used.
You can find the intake manifolds, as well as carburetors, in the accessories section.
Details:
- Grey cast iron reproduction cylinder with Ø 43.0 mm bore
- Slot-controlled
- Ø 19 mm intake
- Optimized Öoverflow channels
- Improved timing
- No spindling of the engine housing necessary (Ø cylinder neck 45.0 mm)
- Ø external exhaust manifold connection: 26 mm
- Incl. Ø 43 mm piston from the Italian manufacturer -GOL-
Differences to the GPO Pomodoro - replica cylinder:
- The BADASS 15 mm & 17 mm intake manifolds fit perfectly on the cylinder
- It is not possible to fit original or swiing intake manifolds
- Thanks to the holes for the cylinder head and blower, there is no risk of damage;
- There is the option of adapting the cylinder to a 50/2 or 502 engine
- Lower intake timing
Installation instructions in German and the matching piston are included in the scope of delivery.
Attention: It is essential to replace the rubber silencers on 503 BL engines with aluminum silencers due to the increased power output in order to avoid fatigue fracture of the exhaust flange.
The aluminum silentblocs, matching gaskets, reinforced clutch springs and other add-on parts such as intake manifolds, carburettors, exhausts, etc. can be found in the accessories section.
