Carburation

#1 PostAuthor: Surfdeneige » Fri May 11, 2007 9:45 am

I have a z1000A2 that runs like a pig. On stripping the carbs I find that they are full of shite. Put them all back together and it runs badly. Can anyone write an idiots guide to carb setup please as my two manuals are pretty vague.

Thanks

First thing to do is balance em using adjustment between carbs.
An old trick i was shown was to hold a piece of tube to your ear and the other end in the carb mouth (with engine running) even a slight difference is very noticable, get them all sounding same,
see how she runs then.

Clean the shit out of the carbs before you put them back together :D

On a more serious note - adjust cam chain, check valve clearance, check ignition and then start on the carbs. Clean thoroughly not only the fuel jets but the air jets, emulsion tubes and the little holes that supply fuel on tickover as well.

Set fuel hieghts first, set slides by sight - I usually just have a gap visible and then screw the tickover adjuster up. 1 1/4 turns out will be a good starting point for the air / or fuel adjuster screw.

I would also like to know the standard opening setting for the pilot screws please as I have a set of carbs to build, and all the pilot screws were different.

What type of carb? fuel adjuster screw (underneath at the front) or air adjuster screw (top side rear) ?

If screw underneath at front, this controls extra fuel addition at low revs, so wind out about 1/2 turn from fully in, out further richens it.
Screw top side, this is an air screw and works by letting more air (not fuel) into idle system, between 1 1/4 & 1 1/2 turns out. Further out weakens mixture :!:
Sorry for stealing ur glory Rich :blah
