BGM PRO Vespa Fast Flow Carburettor Non Autolube (DELLORTO/SPACO) 26/26E PX200

Description Carburettor-BGM PRO-Faster Flow Dellorto / SPACO SI26/26E (Ø=25mm)-Vespa PX200 (type without autolube)DescriptionBGM FASTER FLOW SI carburettor - optimised series carburettors for higher performance enginesHigher-performance engines require a durable and reliable supply of petrol. The BGM PRO Faster Flow carburettors have been optimised to meet these needs and are based on a brand new SI24/24 E or SI26/26 E Dell'Orto/Spaco carburettor. They are completely disassembled, tested, reworked, cleaned and reassembled with great care at our factory, which means that they meet the high demands of a heavily modified engine.MODIFICATIONSan enlarged connecting bore from float chamber to nozzle blockan additional hole in the area of the float needlespring-loaded float needleThese modifications result in a significantly improved fuel supply, which means that there is no shortage of fuel even with very powerful exhaust systems. Especially when using an air funnel, this measure is extremely important to keep the mixture composition stable over the entire speed range. The spring-loaded float needle has a much longer life span and can compensate vibrations very well. The improved fuel supply is of course also an advantage on complete series engines.ADVANTAGESno more empty jet stock when using a strong exhauststill well tuneable even with power above 20HPunobtrusive and powerfulquiet and suitable for everyday use (separate lubrication!)AVAILABLE INØ24mm cross sectionØ26mm Cross sectionfor mixed lubrication 1:50 (oil is added manually during refuelling)for separate lubrication (vehicles with oil pump as standard, from 1984)FIT FOR The carburettor is suitable for all engines with SI20/20D or 24/24E carburettors. These are all Vespa PX80 (V8X), PX125 (VNX), PX150(VLX) and PX200(VSX) models. Please check if the car already has an oil pump (all from 1984 onwards, please choose the carburettor with separate lubrication).They are also suitable for all older engines that have a rotary slide valve control (crankshaft controls the intake). These are for example Vespa VNB, VBA, VBB, Super (VBC/VNC), GL (VLA/VGL), GT/GTR (VNL), Sprint (VBL), Rally(VSD/VSE). It can therefore also be used on the models with originally only 80-150ccm which only have a Ø20mm carburettor ex works.TIP: Carburettors for engines with separate lubrication can be used in principle also on engines without oil pump if the pull rod for the gas slide is exchanged. They only have a hole for the externally supplied oil. On engines without separate lubrication this hole is closed by the carburettor sump.CHANGES Older vehicles (e.g. VBB, VNB, VLA/VGL, VLB) still have small air filters, here you should change to the filter of the PX models. The carburettor sump of the models with original Ø20mm carburettor should be adapted to the larger carburettor in the transition area to the engine. Thus the full cross-section of the carburettor is used.TUNING The built-in fuel injection system is the same as the standard one on the PX200 models.This is already very suitable for many tunings on 177ccm basis, only the main jet should be adjusted. Engines with 200ccm and more need partly also somewhat larger auxiliary nozzles (e.g. 58/160). The tuning takes place in principle from too large (too fat) to lean. The initial nozzle sizes should therefore be selected so that the engine stutters (richer). This gives you a safe starting point for tuning. This is best done with our nozzle sets.NOT E Modified (drilled) air filters or intake funnels always require richer nozzles due to the better working air correction. The intake funnels (also called venturi) may require a smaller main air correction nozzle which has a richer effect (e.g. 140 instead of 160). Tips for the operation of the individual carburettor components can be found in the individual parts (side nozzle, air nozzle, slide). All new SI carburettors are manufactured under licence by the company Spaco in India. These carburettors have been and are used in the series production of Piaggio for a long time. They are of the same quality as the original Dell'Orto carburettors. They also pass the quality assurance at Dell'Orto and are therefore partly packed in Dell'Orto boxes.SUMMARY Very inconspicuous tuning carburettor that already has all the useful modifications on board and also supplies engines with well over 20 hp safely and permanently with petrol!GeneralEAN:4250366615738Carburettorssize venturi:26 mmsize main jet:120main jet type:Dellorto SI (4576)size pilot jet:55/160idle jet type:Dellorto SI (9892)size air jet:160air jet type:Dellorto SI (5827)size choke jet:60choke jet type:Dellorto SI (5582)size atomiser:BE3power jet:size slide:8492.4slide type:flat slidechoke type:manual, cablemounting type air filter:with screwsconnection size air filter:33 mmmounting type intake manifold:flange connectionconnection size intake manifold:60 mmidle gas screw:on topfuel/air mixture screw position:left hand sidefuel hose position:right hand sideconnection size fuel hose:8 mmheight:125 mmwidth:71 mmdepth:80 mmmaterial float chamber:metalconnector for oil hose:vacuum connection:
