XS1100 Idle jet setting?

[RanMan]

Hey All,
I've done the main jet adjustment and found that the idle jets range from 3 turns to 5/8 turn. This seems pretty strange so I'm asking what's a good starting point for these? These were virgin carbs and I've just uncapped the idle jets.

Thanks, Randy

.. a good starting point would be 1 and 1/4 turns out then adjust them either direction from there until you get the smoothest idle from each carb

Sounds good brother. Two of them were around 1-1/4 and 1-3/8 so that may be the range to start with. OHHHHH boy!

Thanks, Randy

RanMan,

Start with all the pilot screws 1-1/4 out.

Do your synch with a mercury stick.

After synch, with stick still attached, one carb at a time, rock the pilot screw in then out to attain the highest possible vacuum reading on that carb

Move to the next carb, do all four

Re-synch.

You should then have the smoothest engine your side of the Mason-Dixon!

I am no professional mechanic, but did you mean to say, "screw in then out to attain the highest possible rpm"?

Skids,

Either way the result will be the same, but it's easier to see the change on the stick than it is to see on the tach
