Post-1979 models use smaller 34 mm (1.3 in) Mikuni CV carbs with needles that seem to be listed in parts menus as being 'fixed' position,(in other words a needle that may only have one clip position). The pilot and main jets can be changed for different sizes. If the 34 mm (1.3 in) CV carb needles only have one fixed clip position.
The engine in the Aprilia SX 50 is sourced from Derbi/Piaggio (D50B0/D50B1). This engine is used in the Derbi Senda DRD/X-Race/X-Treme supermotos and crossers, as well as the 2006 onwards Derbi GPR 50 and Aprilia RS 50 road bikes, although the road bikes feature an electric starter instead of a kickstarter on the supermotos.
The new Mikuni model BST38SS carburetors were 38 mm diameter and featured an additional "Powerjet" high-speed circuit that was used to fine-tune fuel mixture from 10,000 rpm to the rev limiter. In the unrestricted USA bikes, the Powerjet circuit was jetted with a "zero" sized jet and activating the circuit simply required replacing the "zero ...
The GSR versions used two twin-barrel Mikuni-built Solex carburetors for a total of 110 hp (82 kW) . 4G32 ECI engine in a Mitsubishi Mirage. A version with an early iteration of Mitsubishi's MCA lean-burn system (MCA-IIB), fulfilling the intermediate Japanese exhaust regulations for 1975, was called G32A. This was built for less than one year ...
The idle circuit is generally activated by vacuum near the (near closed) throttle plate, where the air speed increases to cause a low-pressure area in the idle passage/port, thus causing fuel to flow through the idle jet. The idle jet is set at some constant value by the carburetor manufacturer, thus flowing a specified amount of fuel.
MiG I-300 (F) - prototype for MiG-9, 1946; MiG's first jet fighter design; MiG I-301 (FS) - production version of MiG-9; MiG I-301T (FT) - experimental two-seat trainer version of MiG-9, 1946; first Soviet aircraft with an ejection seat; MiG I-302 (FP) - experimental version of MiG-9 with the N-37 cannon moved to the side of the fuselage
Jet noise may be reduced by adding features to the exit of the nozzle which increase the surface area of the cylindrical jet. Commercial turbojets and early by-pass engines typically split the jet into multiple lobes. Modern high by-pass turbofans have triangular serrations, called chevrons, which protrude slightly into the propelling jet.
