Here is the DELLORTO VHSB 34 QD carburetor, the most violent of the carburetors! Configured to be efficient, it is a model intended and adjusted for an APRILIA RS, Classic, ... 125cc and CAGIVA engine, flexible mounting with cable choke, with separate lubrication without vacuum connection and socket for antifreeze circuit.
Obviously, this is not a replica but a real carburetor from the Italian house DELLORTO. This version is configured with a DP266 needle well, a main jet of 160 large steps, a choke nozzle of 60, an idle jet of 40, a K57 needle. With this basic configuration, this carburetor is clearly intended for racing configurations with good diagrams and requiring more meticulous adjustments. The fixing at the level of the pipe is in Ø44mm diameter with machined anti-slip lip, moreover the fixing for air filter remains in Ø64mm. The finish is obviously perfect at all levels on these models and the photos are there to prove it!
Carburetors with a round bushel are easier to adjust over the entire speed range, for example from 4,000 to 16,000 rpm. The flat bushels generally used on the motocross, offer more engine response (the engine responds faster to the opening of the valve), there are also special flat bushel versions suitable for competition, track, and high revs ...
We note that a bushel round is the best choice for riding every day with simple adjustment, low consumption, excellent performance at high revs, very good stability (although fashion is oriented to low bushels flat ranges ...) . In addition, we generally recommend a flat bushel on cylinder with bar exhaust while the round bushel would lend itself better to cylinders with booster or oval exhaust.
