DELL'ORTO 105-128 jet kit for SI

Description

DELL'ORTO 105-128 jet set for SI 20.15-17 A-D / 20.20 - 26.26E / G / H / 27.23 jet (105-108-110-112-115-118-120-122-125-128) In the SI carburettor, the jet is located in the jet block under the main jet mixer tube and air correction. It is responsible for producing a certain amount of fuel available for premixing. With all optimisation measures, however small, it is necessary that the main jets be raised, as they mainly affect the mid and high rev range. Their effect is closely related to the other components of the SI jet block and for complete tuning, it is necessary that all components involved be adjusted accordingly. Please note that we only use Orto jets. Those who have already tuned carburettors and found that the actual jet diameter does not match the number engraved on the side, that is what we are talking about. If 105 is written on it, then there should be 105 in it! Anything else is a cheap trick. The size of the jets increases based on stages one, two and three. The jets become increasingly richer. Simply connect the corresponding size to a non-4026 part. The jets from 142 upwards have been specially redesigned under the SERIE PRO logo as DELL'ORTO is only able to supply jets up to 140. The 105-128 and 130-140 SI ejection kits each contain 5 and/or 10 jets and are an ideal basic programme for any tuner. Conclusion: A selection of main jets is an absolute must for every scooter rider.
