DELL`ORTO by DRT SI 20.20-26.26 carburettor float cover, for Vespa 125 TS/150 Sprint V/Rally/PX80-200/PE/Lusso/T5 with Ø 5.2 mm float needle, for QUATTRINI 177/POLINI/MALOSSI 208cc The DELL `ORTO SI 20.20H/24.24H chamber float cover is a special treatment and a perfect upgrade for all 20-24 SI carburettors. With its 5.2 mm float needle, it solves the problem of reaching full throttle. The DELL `ORTO float chamber cover, which has been revised by DRT, is also intended for all Vespa riders whose hands tend to get nervous on the clutch when riding downhill on the motorway. It has a larger valve and a 5.2 mm float needle. The 0.7 mm hole ensures that enough mixture always flows through at full throttle. On these covers, the feed hole from the float chamber to the main jet should be drilled out from 1.5 mm to 1.8 mm (PX177) or 2.0 mm (PX200). Conclusion: an excellent upgrade for the original SI carburettor. Ideal for largeframes running constantly at full throttle. This float chamber cover with 5.2 mm float needle solves the problem of piston seizure at full throttle. Please drill open the feed hole from 1.5 mm to 1.8 mm (PX177) or 2.0 mm (PX200).
