Description
CARBURETTOR TUNING SET BGM FOR DELL'ORTO PHBH28 / PHBH30
Tuning kit for the classic Dell'Orto PHBH series or its replicas (YSN)
SUPPLY
Main jets: 130,135
secondary jets: 58,60
Mixing tube: AS266
Needles: X3, X7, X13
The set is a very good basic tuning for almost all tuned Vespa/Lambretta engines.
MAIN NOZZLE
The main jet settles around 130-135 for most engine setups. Only rotary valve controlled Vespa engines usually run significantly leaner (120-125).
NEBENDÜSE
The secondary jet tends to be used in the 55 range in the Vespa range. It is usually part of the basic set-up of the PHBH carburettors and is therefore not included in this set.
Slotted Lambretta engines usually require the size of the side jets included in this set.
NEEDLE
In the Vespa area the X2 needle is used very often, but this is installed in 90% of all PHBH from the factory, therefore it is not included in this set.
The X7 and X13 needles are variants of the X2 needle. The X3 needle has also proven to be a very good all-round needle.
MIXING TUBE
The PHBH carburettors are adapted to their intended use (2-stroke or 4-stroke) via the mixing tube.
Often the AV type is used for 2-strokes. However, with this type of carburettor the engines often tend to grease up with little slide stroke. The (shorter) AS type runs much better here.
With this set you are able to provide a very good basic setup for your engine.
