This product fits on almost all products Product description
The DELL’ORTO PHB series carburettors are the first choice for the area of midrange tuning. They belong to the drum carburettor category (rounded throttle slide) and are available for smallframes (PHBL) and largeframes (PHBH) with a 24-30mm outlet. The DELL’ORTO PHB carburettors are also the right choice for everyone who wants to get the best possible performance from their scooter at the lowest possible expense. Their design is more complex than on the SI or SHB but the DELL’ORTO PHB carburettors also have more room for individual settings. These can be made with a sensible combination of slide (available with different cutaways), needle, calibrator and jets from the wide range of DELL’ORTO products. The carburettors that we supply have a basic setting which enables problem-free installation. The fine tuning to suit the corresponding engine has to be completed by the individual and specific to the engine in question! The designation ‘S’ (ital. sinistra = left) on the carburettor means: Mix regulating screw to the left of the direction of induction; ‘D’ (ital. destra = right), means: Mix regulating screw to the right of the direction of induction. This is important for the installation of the carburettor. The carburettors are fitted with a flip-up choke as standard, but can easily be converted to a cable choke (e.g. part no 40320000) with the corresponding kit.
Conclusion
: The best price-performance ratio. Perfect midrange tuning for those with more limited wallets.
Required under all circumstances: Suitable intake manifolds (watch the connection width), sport air filter and air bellow. The best idea is to experimant with the jetting kit (e.g. part no 40270200) when completing the setting work!

“An amazing component! I drive the carburettor on Pinasco with long stroke. It gives great torque and is good fun for the money. Explanation of the carburettor markings: BD carb.= Adjustment screw to the right of the airflow direction BS carb.= Adjustment screw to the left of the airflow direction
