Yes. In my experience, at 2 to 2 1/2 turns out and a larger pilot - it works better. Then you can turn down idle (back it out) to improve separation of carb circuits.... The air screw will then have more effect - e.g. you will be able to fine tune - like a quarter turn will make a difference, etc.
If you are worried about losing idle screw - you could put a very small dab of low strength loctite on it's threads. Let it dry completely prior to installing. jeff

Thanks for the tips about being 2 1/2 turns out on the air screw. I will try that this weekend.

In my mind - #8 slide is good along with everything else.... Be sure to re-set idle screw to lower level.

Don't be afraid to try needles. You just can't jet the wrong needle to work.

When it's right you'll know. Wheelies at will mean you're close. Wheelies when you don't quite expect are the biz.

Thanks for the guidance guys. I will adjust the idle screw more closed and try 40 and 42 Pilot Jets this weekend with the Suzuki NECJ needle.

I made changes as you suggested and noticed great improvements. Increased MJ, PJ, opened AS to 2.5, lowered slide so just barely open, raised NECJ clip to eliminate midrange blubbering. Ended up at top clip. Think I should get a leaner needle since I am at the top clip and I usually ride at much warmer temperatures 90 to 100 deg F.
More low end from below idle. When I crack open the throttle from idle the front wheel will come up. Power builds linearly into a Good clean midrange that revs out nicely. 2007 Ec300 Temps 60 deg F 38mm AS1 PJ 42 (was 38) MJ 172 (was 168) Slide 8 AS 2.5 out (was 1.5) NECJ top clip (was clip 3) Idle screw adjuster to open slide just a hair |
