Carburettor kit -BGM PRO 195-225 cc- Lambretta LI, LIS, SX, TV (2nd series, 3rd series), DL, GP - Ø=30mm Polini
Part no.:
BGM8597
Description
Carburettor kit especially for the BGM RT Lambretta cylinder. The carburettor kits are based on the Polini carburettors and our bgm PRO intake manifold. The manifold comes with a MB carburetor rubber and offers the maximum possible distance between the carburetor and the side cover. The carburettor is almost in the original position and straight. The original or bgm air filter box (BGM4488) can be used without any problems. The carburetors can be tuned - like the original Keihin PWK's - very well and convince with good consumption values.
A good initial jetting for the RT cylinders and the bgm Lambretta Big Box consists of:

TIP: Polini carburettors are very sensitive to the adjustment of the mixture screw, just like the original PWK carburettors. If the engine gets stuck at too high a speed after full throttle, the side jet is usually too grease. In order to achieve an acceptable idle speed with the too rich auxiliary jet, the idle speed is usually increased and the mixture screw is turned out too far (= leaner).
This compensation of the rich auxiliary jet via the settings on the carburetor leads to the engine getting stuck at a very high speed, although the gas has already been turned back to zero.
With a smaller side jet the idle speed can be adjusted to a normal level again and the idle mixture can be adjusted (screwed in) via the mixture screw also to a richer mixture.If necessary the float level should be observed. This is often adjusted inadvertently when dismantling the float chamber. To do this, always remove the float chamber with the carburettor upside down. Otherwise the float can get caught in the inclined overflow pipe.
Recommended float level: 21mm (Turn the carburettor upside down here too: Measured from sealing edge of float chamber to upper edge of float ).
