anyone have weber adjustment info for my mechanic, he's stumped? the run fine above 4000 rpm but sputter and choke below that

i understand others have replaced the webers with mukuni's?

when is this advisable and where can they be had? cost?

thanks guys, new user here

appreciate your help

Look for the "Ducati Cuddle" postings by Skins ( I believe - sorry if I got that wrong)

As far as when is it advisable to change?

Basically I think the answer is IF you can get the Weber to work then don't bother changing, If like most of us on here you can't then change as soon as you can.
Cost varies country to Country but when I did mine a few years ago it came to around £100 with used carbs and new cables and inlets with a bit of shopping around. Jets were extra

Taking carbs and inlets from a 750ss or monster is the way to go. Paso 750 is the Guru on all this. I think there are some permanent postings in the FAQ sections of the site. Also search the Yahoogroup for postings if you don't find what you are looking for.

The weber is supposed to set for a fast idle if you are tuning... @ 1500 as this is the speed the main jets are working... if it's having trouble at normal idle this would point to the idle jets. try taking them out and cleaning them...

every time my dukess runs bad over 4000-6000 rpm I understand it's the time to change spark plugs and test ignition plant

thanks guys

my mechanic now says he wants to put on a 750ss fcr kits part number 016720 keihen carbs

will this work on the 1988 750 paso?

he couldn't think of a more expensive way of solving the problem then?

No kidding ... FCR's ain't cheap.

If you want to work on tuning the Weber some, send a PM to jfiore - he has a great write-up detailing his experiences with the Weber. He's worked his into shape, and has the recipe for anyone else to follow.

There's a handful of links in the tech FAQ digest about it, too

here`s some more info about Webers from David Harvey`s old site

http://www.geocities.com/750paso/paso/906carb.htm

http://www.geocities.com/750paso/paso/906carb2.htm

and from Baukes

http://www.geocities.com/750paso/paso/weber.html

http://www.geocities.com/750paso/paso/f ... blues.html

don`t change to FCRs if you aren`t after a performance boost. But also if you are this modification should come with others. Therefore the stock Mikuni from a Supersport/Monster is the better and cheaper choice if you just want a reliable carb.
However, the Weber can work nicely it just needs some more attention.
Hope the links help.

funny subject to me this as they've been fine on my bike, they do have a flat spot {reviews] though this can be sorted by the wiring mods elsewhere in this forum. also are you in the uk ill let you know what spark plug to use this also took time with me as sometimes it would run rich then another day not. desmodave:

Well tuned Webers are well worth keeping if you are not interested in commuting on your Paso (& you should not be because that is not what they are for).
Tune them well & engoy the road
