Jet SI Push In SIP 130 (SI 20.15-17 A-D/20.20 -26.26E/G/H/27.23 - Main Jet) (Vespa)

The jet si push in sip 135 (si 20.15-17 a-d/20.20 -26.26e/g/h/27.23 - main jet) (vespa) offers a replacement , keeping your scooter in peak condition. In the SI carburettor, the main jet is located in the jet block under the mixer tube and main air correction jet. It is responsible for making a certain amount of petrol available for premixing. With all tuning , no matter how small, it is necessary for the main jets to be raised, as they mainly impact on the middle and upper rev range. Their effect is linked very closely with the other components of the middle SI jet block and for comprehensive tuning, it is necessary for all of the components to be accordingly. In recent times have regrettably been unable to deliver some of the more important jet sizes for their carburettors. The quality of certain after-market reproduction jets is unacceptable for us at . For these reasons we have teamed up with the people at KOSO to have our own jets , with the logo! While the sizes of the jets can vary up to +/- 0.05mm from the given value, the jets are much more precisely with their sizes only varying by +/- 0.005mm. Those who've tuned carburettors and found the actual jet size does not correspond to the number on the side, know what we're talking about. If 105 is written on it, then there'd better be 105 in it! else is a cheap trick. The size of the jets increases on the basis of one, two and three stages. The jets get increasingly richer. Simply attach the corresponding size to part no 4026. The SI 105-128 and 130-140 jetting kits each contain 5 and/or 10 jets and are an ideal basic programme for any tuner. Unfortunately, does not follow a consistent system when naming its jets . , it can be assumed that the number by which the single nozzle is named indicates the of the hole in 1 / 100mm. This means that e.g. a 107 jet has a bore of 1.07mm. On the main jets for the SI carburetor that is only partially true. Up to a size of 120, the bore corresponds to the jet designation. From 120, the actual increases faster than the designation of the jets . This is independent of fluctuations or manufacturing tolerances, which further complicates a clean gradation between the numbers. When manufacturing the jets for the SI carburetor, we had to decide whether we would make it exactly like or if we had all jets manufactured exactly according to the respective designation. We have decided for an exact production according to the given measure. This better transferable results and a finer gradation. Unfortunately, this leads to the problem that a tool box with a mixed jet set makes carburetor tuning very difficult. Of course, we recommend simply using the jet set from because they are manufactured with the tolerances available on the market. For the switch from to jets, we have created a table. With their help can be , which corresponds to jet of the respective jet: in mm Size Size 0,45 45 45 1,19 119 119 1,20 - 120 1,22 120 122 1,25 122 125 1,28 125 128 1,30 - 130 1,31 128 - 1,32 - 132 1,34 130 - 1,35 - 135 1,36 132 - 1,38 135 138 1,40 - 140 1,42 138 142 1,45 140 145 1,48 142 148 1,50 145 150 1,52 - 152 1,54 148 - 1,55 150 155 1,58 152 158 1,60 155 160 1,62 - 162 1,64 158 - 1,65 160 165 Conclusion: Finest quality, perfect value for money and exact sizes are once more available. For optimum tuning in the middle and upper rev range order a corresponding mixer tube (e.g. BE4 art no. ) at the same time. Manufactured by SIP, Vespa, for quality and reliability. A must-have for any scooter enthusiast.
