Slider question

[Patswild300]

I have a Gas gas Wild 300 two stroke. I just bought the bike and the bottom end need some cleaning up and it loads up. I'm at 5200 feet. The carb is jetted
Main 150
pilot 40 ...1/2 a turn out
needle in the top position n1ef is the needle number
slide is a #6
I have a #9 slide.

What does the slide numbers mean and whats the difference between a #6 and a #9?
Does anybody have a start point on what I should start with?
It also came with another needle #CHN

Check the jetting thread with the chart. You motor is the same as the EC300 so look for similar situations. Jetting is alway talked about on here.

Go to the bottom of this article for throttle slide (cutaway).

Here's a direct link to the current jetting database.

A 150 MJ would cook both my EC300s in minutes at 5200. I run a 165 to 168 at a 6000 ft ASL base in Idaho.

There is also a very big difference between a #6 and #9 slide, with #9 being a lot leaner (#6,#7,#8, #9, rich to lean). I could be wrong, but I would think that with the Quad being a lot more load on the motor than the bike, you would want to be richer for the same conditions if anything.

Check the float height before any jetting sessions.

Thanks for the info guys,

Well jetted it today . Dropped the pilot to a #35 1 turn on the air fuel screw, and put the needle in the 2nd to the top slot and upped the main to a 165. Also put in my new UNI filter and new plug. Bike ran great and better then its ever have since ive owned it. But thats only a few weeks.. Only problem is my pilot and air fuel. I feel the bottom end should be better then it is and I dont know what way to go. Seems boggy then hits hard in the mid to top..
Any idea's?

I'm at sea-level with an EC300 bike but found the CCK needle really helped. I tried all sorts before including LTR and couldn't get a smooth power delivery. I ended up jetting very lean (35P, N1EF on #2, 178M, #7 slide) as it "appears" to run better that way in the woods but you get that hit and it's dangerously lean when you come to a fast section. It seems better because it gets rid of most of the 4 stroking at small throttle openings. I now have 42P, CCK on #3, 180M, #7 slide and it's much better. Could probably go to 45P.

Make sure float height is correct before experimenting. It was the needle that made the difference for me, until I had that right no pilot or main change could sort it. Thanks to Pobit for suggesting CCK needle.
