The BGM FASTER FLOW SI carburettor is based on a brand new SI24/24 E Dell''Orto/Spaco carburettor.
This one is revised by Bgm whereby it also meets the high demands of a strongly modified engine.
They use a float chamber of the Vespa Cosa models which is modifyde again.
The Cosa float chamber cover already has a larger float needle ex works which is additionally equipped with a spring. This effectively prevents excessive pressure at the sensitive rubberized needle tip.
In order to meet the increased fuel requirements of a tuned engine, the carburetor was optimized and a modification made to the through bore between the shimmer chamber and the nozzle block. Normally only 1.5mm in diameter, the FASTER FLOW carburettor already has a 1.8mm bore. This allows it to permanently supply main jets up to a size of 170 with tidy fuel.
These two modifications lead to a significantly improved fuel supply, which means that there is no fuel shortage even with very strong exhaust systems. Especially when using an air funnel like e.g. Polini, this measure is extremely important to keep the mixture composition stable over the whole speed range.
Here again all advantages:
- no more empty float chamber when using a strong exhaust
- also well tunable for performances above 20PS
- unobtrusive and powerful
- quiet and suitable for everyday use (separate lubrication!))
