Carburettor DELLORTO PHBG 19,5 AS choke lever, rigid, without separate greasing

If you want to preserve a low consumption while having more performance than a SHA or other model for endurance or road for example, the PHBG model will make a very good compromise. This low cost carburetor is of very high quality and has a multitude of settings: richness screw, idle jet, needle bushel ... This model is the AS (also exists in BD model, AD, DS, DD, CS black edition, or BS), this 19.5mm is just above the 19mm model, its main difference with the 19.5mm CS is that it does not have separate lubrication, so it is cheaper. It is rigidly mounted with a lever choke, you can also switch to cable choke without difficulty. In relation to the SHA carburettor, this model is much more precise, performing at the recovery, acceleration and peak speed. This model has a separate greasing, you do not have to use it and it comes with a original shutter on this socket. This model also comes with a black admission tulip! This tulip improves performance and is Ø60mm, so you can install a Ø60mm filter attachment or remove this tulip to install a filter in Ø PHBG Ø32mm standard.

Tip : accompany it with a pipe of 19 or 20mm, slats of carbon valves, pipe a maximum aligned with the valves, you can simply use an air filter of origin but also a cornet. Plan an array of sprinklers from 76 to 95 depending on the filter used.
