Ok what I have got from the manual is that you start at the factory setting.

On my 1200 84 it is 3 1/2 turns out.



You turn out 1/2 turn and watch the idel raise. Keep doing this on all carbs until the idle drops when it drops, I dont know what else to do.



DO you turn out all carbs before watching for the idle drop or each one individually.



What kind of tach do I need and what does it connect to?



Really guys I read it 3 times an still am lost.

An inductive tach is the easiest, it just clamps over a plug wire. The RPM will show double what it actually is. Turn all 4 out 1/2 turn at a time until the idle stops increasing and starts to decrease.Adjust the main idle speed then do the individual adjustments.

You will need a tach that will show a 50 rpm change. The one on the bike won't work. You work with 1 carb at a time. I don't remember what to do after the rpm drops. :?

On older carbs for sleds, lawn mowers etc, you would turn the adjuster in or out to get the highest idle which was always the leanest mixture, than turn out 1/2 turn to richen it up so you didnt burn a piston or valve. I suspect that this is the same principal!?

I think I understand it now. Turn them all out a 1/2 turn at a time until the idle drops. This wouold be full lean. Then back in each seperate one and watch the idle once they are set the books calls for one full turn bACK.
