Installed ECP kit and let me tell you it now runs STRONG, but I have a low speed "burble" that is apparent at partial throttle. Not a huge issue but just an annoyance. It idles fine and cleans up quickly and pulls very strong once past approx quarter throttle.
I am leaning towards the pilots and a slight fuel screw adjustment, Fred can you point me in a direction as I want to limit the times I need to pull the carbs.
Thanks!

You must first be absolutely certain that the carbs are synchronized! The burble that you hear might also be the incresed noise due to the removal of the airbox. Back in the old days we all took the air filter out of mom and dads car to make it sound like a 4 barrel. This is similar. If there is no hesitation it is not lean. "Burble" makes me want to think rich however. Make sure the fuel screws are all closed lightly and then opened to 1.5 to 2.0 turns out. They are all set differently from the factory for pollution reasons, so be sure to seat them all closed lightly and then open them. Try richening and leaning the needle as well.

Freddie,
I synched the carbs and preset the screws as instructed, but the burble is a definate miss (slight) of sorts, as I mentioned it is only just off idle and in the low RPMs and it cleans up perfectly once into quarter throttle range which is steering me away from the needles.
It is very minor but it is present.
Idea's?
I should have mentioned I am also running White Knuckle QC-1 exhaust, but I would doubt that has much to do with anything.

I have ECP and the Qc-1 as well. Did the sync, played with it a while, and it seemed like the Ring-free fuel additve is what cleaned up what I could not find myself. I can say the Rx rocks, but it ain't as close to the Apex as I thought it would be.

I had the same thing and raised my needles on click. It didn't completey get rid of the burble but it's about 80 percent gone.

Remove each cap/coil. Then remove the upper rubber boot on the cap/coil. Re-install the caps and run the engine outside when dark or inside the garage with the lights off. Look down into the sparkplug well and see if you witness any arcing. If you do get some dielectric grease and smear it over the offending cap inside and out. This will get you riding while you wait for the new caps/coils to arrive from your dealer.
