Question on pilot adjustment

[BigBoyinMS]

For those that have made adjustments to their pilot circuits... what technique do you use? With 4 carbs can you hear an idle change when tuning each carb?

 

I plugged my AIS and synched my carbs last weekend. I also popped the caps and turned the pilots out 1/4 turn each. Since then the bike is running great but I'm now getting a bit of popping through the exhaust on decel. That signifies a lean condition but I turned the pilots out not in.

I've been told that you can listen to the idle but my ears aren't that good. I use a Morgan Colortune. It is like a spark plug with a sightglass so that you can see the color of the spark. Most modern dealers would use an exhaust gas analyzer.

If the mufflers are still popping, turn 'em out some more.

 

Yes, the screws can be adjusted with the carbs still in the bike. Even the caps can be popped off without taking anything apart. You just need a long screwdriver.

I had popping on one side and I could listen as I adjusted, it was the left rear and as I backed the screw out the Idle smoothed out and it took care of the popping

about 15K ago. No problem since.

Thanks for the replies, guys.

 

And Gambler, the caps look like brass cones. You can see them on the opposite side by looking between the carbs. With a long flat blade screwdriver you can pry them off and adjust them. They pry off easily.

Thanks Peg & Big , I will be doing ajustments soon
