Also he moved his clip down to third position but wont that only lean out the top.
Nothing like owning a new bike that wont run. GOOD THING I OWN BLUE, it starts everytime.

Lowering the clip (raising the needle)will richen the mid range. To set the air screw, first the bike has to be idling. He has to turn in the air screw until the engine starts racing. Then, slowly back it out until he hears the engine start to stumble, then turn it in 1/2 turn.

1) Remove Gas cap from KTM 380.
2) Discard or sell remainder of the KTM under gas cap.
3) Get new Yamaha WR426.
4) Replace gas cap on new Yamaha.
5) Ride and enjoy

here it is Quote>>
I currently run a 175 main and
the (I think) "H" needle on with the clip on the second notch down.
My bike revs out better than my buddies bikes do, so maybe my jetting
is right and they are running lean.?? I may be a tad rich on top
but I tend to rev a lot so I'm ok with that.
I run Silkolene Comp2 oil at between 40-36:1.
Hope this is of help.

Ok, we can do them too -
The 380exc is rich because of the triple taper needle. It will be something like NOZH. Try the next clip leaner (#2) and possibly a leaner pilot jet. There are optional leaner needles and the next step is NOZI.
Pilot jet - #42
AIR screw - 1 1/2 turns out
Needle- NOZH or NOZI in clip #2
Main jet doesn't matter for low end.
If it still isn't good enough, go to a Honda needle from the CR250 - R1369LS in clip #3. This will REALLY make it run more clean down low. Go back to the #45 pilot with this needle.
Just do it -PROBLEM SOLVED, NO PLUG FOULING
I have a bunch of posts on www.dirtrider.net under the KTM section on this.
