The technically refined Dell’Orto flat slide VHS carburettors are significantly better than simple drum carburettors and therefore improve the performance and efficiency of the engine. The decisive factor in this case is the (double) slide model: In a flat, square design, the protruding edges of the carburetor drum were omitted. Due to the straight tearing edge of the flat guide it is possible to achieve a smooth, streamlined air passage and thus a superior cylinder filling. With a socket of up to 39.5mm they are not only suitable for use on largeframe high performance motors but also for high end smallframe set-ups. We have the VHS series in four versions (B, C, H, T). Depending on the design they have a pre-installed folding choke (VHSH / T) and a mixture cable. To adjust your carburettor, you can choose from DELLORTO’s wide range of high-quality jets. The needles, main jets and idler jets all generally come from the proven solar time product range. The VHST convinces with its compact design, which is not only clear during installation, but also in terms of improved throttle response and shifting. A chromed slide, 2 individually connected floats and spring loaded round needle of the shut-off valve float the overall positive picture. The VHST is a tribute to the classic racing carburettors of the 1960s – and is available in a particularly elegant design as a Red Edition. The VHSH 30 CS is also one of the absolute high performance carburetors. It was developed by DELLORTO in collaboration with the main ma-nufacturers of trolley engines and has been used ever since as a series carburettor in the ICC formula. It convinces with a smooth running intake surface, a screw on carburettor cap, a separate central screw plate for quick main jet changes, an integrated fuel filter and a spring-mounted float needle valve. The VHSB series is one of Dellorto’s largest and most powerful carburetors. Its oval shaped intake is as good as it gets in the field of high end carburetor tuning! With the 39.5 VHSC BD deciding the largest flat guide carburettor available in the DELLORTO range. Conclusion: Flat slides are significantly superior to drum carburetors low end and mid rev in particular! SIP-TIP: A jet set (e.g. aircraft at rest, 5mm, code 40100000 and main jet, 6mm, 40270100) help when tuning the VHS carburetor. Dont forget the matching RAMAIR air filter (for example part no 40390000)! SIP community corax user part no 40043000: Carburettor Cool. Polished slide. Good tune. top!
