| Post subject: | Help - Which carb to use? |
Having read a few articles on here; am determined to fit new carbs on my Paso. (Still running the old weber's). According to most testimonies, the 40mm Dellorto's sound most optomistic (and my final choice), however, have been tempted by a cheap set of webers. I know 1 step forward, 2 steps back. A risk. These are described as 40 DCNF performance carbs. I know they have been used on the 86'; MG maestro, Lamborghini Urraco P33 and SS Ferrari Dino 308 GT4, but are they the same one's already in my Paso. i.e. The original fittings? :umm: Can someone help please. |

Naster - I gotta go with the Aussie on this one - why not just rebuild & set up your own Weber properly - at the end of the day - it helps keep your bike original....... |

Or at least hang onto your original Weber if you do decide to swap out. I have two Weber 44s - one installed, one rebuilt in a box. Two different jettings. Neither one of which is making me 100% satisfied. But like red said - it's an open road specialist, not a gridlocker. I haven't heard anything of the DCNF 40s, so if you do give it a shot, let us know!

If the carbs are 40 DCNF, they are the same type as the stock carbs (44 DCNF). Although the body of the 40 is smaller than the 44, they can be set up to work for the same application, up to the maximum diameter (40 mm) of the carb body. The important things for setting up and using the carbs are (in order of importance): 1. Venturi size - measure the inside diameter of the main venturis, they should be sized between 32 mm and 36 mm. The stock carbs have 36 mm venturis, but they seem to be a little large for proper fuel/air mixture across the full range of throttle openings - they work better at full throttle. 34 or 32 mm venturis will work better at part throttle, but will not flow as much fuel at full throttle. 2. Main jets - with 36 mm venturis, a main jet size of .155 to .165 will be necessary, depending on what exhaust you are using. If the venturis are smaller, you will need a main jet size that is smaller, probably .140 to .150. 3. Air corrector jets - with 36 mm venturis and corresponding main jets, you will need air corrector jet sizes of .155 to .160. With smaller venturis and smaller main jets, you may need to go a little smaller, maybe .150 to .155. 4. Idle jets - .160. I hope this helps.... |

Cheers for all your advice guyz. :thumbup: Wreckon I will hold on to the orginal webers, (just to keep the bike original). :thumbup: However, really wanna upgrade those carbs. Whenever i take her for a ride, can't help thinking she's not quite giving me the kick she could. That fuel is definately not reaching the engine in good time. Just my humble opinion, but: surely, that engine deserves justice to perform its full potential. Besides, where I live (London) really could do with that extra response to cut through traffic. Gotta comment though, Paso exterior is absolutely beautifull. Only sex turns me on more. (sorry if thats to much information). Never been attached to another bike (ever). Those 'itis' know how to design sexy wheels. (Shame there not just as good when it comes to electrics and fuel feeding.) Thats enough for me to keep her. Will probably buy those webers. There only £75 (about $150 US dollars) Will let you know how they perform. Please, if anyone has any further thoughts/comments on these webers, could really do with the input. Nice one, one and all. |
