Goes well with (optional):

Mediterranean 41 mm cast iron racing cylinder with 55 cc for your Sachs moped / moped with 503 2AL, AAL, 2BL, ABL CH engine.

The GPO Pomodoro cylinder kit (Italian for tomato) is the sun-ripened, refreshing alternative to comparable greenhouse racing cylinders. It impresses with its freshness in the lower rev range, powerful acceleration and pulling power, as well as a fruity finish in the upper rev range. The cylinder absorbs more nutrients than original ones, transforming them into juicy, powerful pulp and exuding a tantalizing aroma of oil. A real treat for your engine that fills the streets with passionate flavors.

Details:

  • Grey cast iron reproduction cylinder with Ø 41.0 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 connection exhaust manifold: 26 mm
  • incl. Ø 41 mm GPO piston

Differences to the original BADASS cylinder:

  • Original or swiing® intake manifolds can be fitted
  • The BADASS 15 mm & 17 mm intake manifolds cannot be fitted
  • The cylinder cannot be adapted to a 502 or 50/2 engine
  • Higher intake timing vs;higher intake timing compared to the BADASS

Due to the correct angle of the intake surface, both original and swiing® brand intake manifolds and carburettors fit under the side valving without the need for adjustments.
The GPO piston improves intake timing, resulting in higher engine speeds. The edges of all ports are smoothed, which enables optimum mixture flow.

Note: Replace the rubber silentblocs on 503 BL engines with aluminum bladders to avoid exhaust flange fatigue fractures at increased power. Ideally, you should use reinforced clutch springs to ensure that all the vitamins and minerals end up on the plate. For an additional flavor note, you can install a 32 mm resonance pot.

Protect the Pomodoro cylinder from heat with the original Sachs cylinder shield or the Pergola cylinder head in the optionally available accessories. You will also find a suitable swiing® irrigation system and piping there.
