Carburettor DELLORTO VHST 28 BS 1 flexible racing choke lever without separate greasing or depression

We finally present to you this version of the VHST 28 carburettor reference 09357, this version is expressly revised and corrected especially for engines with very high diagrams (we recommend it on 50cc 80cc hyper Racing kits with minimum diagrams of 129/190). On this model the jet has been changed to 142, the starter jet is 60 and the idle jet (also secondary) is size 35.

For the needle well dellorto opted for an HE 269, the needle is a D 41. As much to say to you that in relation to the other VHST 28 standard this carburetor was expressly designed only for the very pushed engines! Apart from these differences this carburetor remains completely identical so it is a top-of-the-range model with a lever choke without separate lubrication, the finish is perfect, the flat bushel offers a breathtaking recovery. DELLORTO worked at length on its needle bushel assembly made by screws / spring.

It is a rework weapon and it is much easier to adjust than many competitor's flat bushels. Thanks to its detachable 2-part float on axis, you can give it an ever greater inclination. The bushel is therefore flat and has a laser cut, it is basic true chrome, no plastic at Dellorto… You will appreciate the Dellorto standard nozzle sizes in order to find the parts. It really is a very high quality bushel. The air filter inlet diffusion is excellent! A model to discover ... the Italians Dellorto once again show their skills, and they have fine-tuned the finish, the accessories such as the aluminum tank ... quick change of the nozzle by plug.

Fixing diameter in pipe: 36mm
