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.
 
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.
 
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.

Great info.....The float was the first thing I set.. Where can I get the CCK needle? Do you think I should go to a #7 slider?

Any Keihin agent should stock them. It's a standard Keihin needle. I believe Sudco are one of the main agents in the US?
 
I would try a 40 pilot, needle clip in the #3 position based on you brief description of the midrange bog. With the larger load from the quad, I would keep going up on my main jet until the performance dropped off. You might be able to pull a up to a 175 at the higher elevations and it's important if you plan on spending alot of your time on the pipe/MJ.

Thanks Mike
It had a #40 pilot and it was worse I think, Thats why I went with the #35 and went another half a turn out. I was going to up the main another size up and see..I also tried the needle in the middle and it had the hesitation so I went to the 2nd fron the top and it cleaned it up alot..
 
The LTR powervalve cover helps with bottom end. We put one on a Wild HP 240 and it made a difference on the bottom end. I also have one on my EC200 and noticed a difference as soon as I put it on.
