Need advice, just put the JD Kit and pipe on

Just installed the Kit, Blue needle 3rd position down from the top, 170 Main, fuel screw 1 1/4 turn, along with a power core 4 and I opened up the right side cutouts on the Air box. Starts no problem, idles no problem, It seems to stumble a little at about 1/3 throttle, after that...... Tons of midrange power!!!!! I came back in with a huge smile on my face, I can tell it's gonna be awesome when I get it right.

BTW I tried the clip 5 posistion down from the top and it seemed to stumble even more.

Current temp is 67 and altitude is 161. Will normally ride below 4000ft.

:cry:

you dont say what your current pilot jet is? see my signiture line, our setups are similar. your pilot should be around a 48.

Try the red needle in clip #5 from the top. 48 pilot

I like the blue needle below 70 degrees. The red needle is good for 70 degrees and up. In your case you may want to try the red needle in a rich position. :cry:
