bike carbs on b14?

[kohshin]

hello,
someones see a b14 with bike carbs??
i such on volvo and renault but not found

[kohshin]

the intake pipe consists of two tubes, is it possible that the best will be to put 2 carburetors and not 4?

[classicswede]

I have looked at making some manifolds to change the carb. As a good carb for economy I have thought about a single 1 3/4 su or for power a single Webber 40dcoe. As to the bike carbs I would say 2 carbs would do what is needed and 4 carbs are likely to not work as well or at least no better than 2

for you , what's a good size for 2 bike carbs?

I wanted to take a super intake manifold 5 to start but it is not at all the same size as the volvo

i see this post on a mini's forum
http://www.theminiforum.co.uk/forums/to ... onversion/

one man use a TDM850 twin carbs (2X mikuni 38) for a mini 1380cc and 2 intake pipe
mabye it's a good direction for this installation

That sort of size would get the job done but no smaller.

I can have a weber 44 dcnf from a ducati 750 , is it good??
and the tdm850's carbs in 38 is the same of ducati monster 600/900cc

I know very little about bike carbs in all honesty. The 44 would normally refer to the throat size so size wise it will work. Most bike carbs are normally very adjustable but Webber carbs on a car need different chokes and tubes to adjust them, I do not know what the situation with bike variants is.

but 44 it's not to big for my 1.4 ?

[classicswede]

No if I was going single webber I would go with a 45 but 44 is close enough not to matter. If going TB then 40mm is big enough as there is no choke reducing the size.

this is a ducati's carbs spec

for you, what's the best spec (main jet and idle jet) for a B14?
