all i can suggest is with the 2152 DJ kit set for stage 1 (no intake or major exhaust mods) a/f=3, needle=3, mj=dj116 (sea level, fl), it will run smooth and strong.....

Just found this thread - I may have the surge issue but I've also been playing with my TM36 jetting so it could be that causing it too... Glad I found this.

I'll try it.

I got a 07 & have a stumble, is it possible that this wiring issue effects bikes in 07, or do I need to work on my jets more?

Cut the wire an inch from the plug, made new ground and regrounded to the screw next to it where an already existing ground was (i think on the engine) fixed the problem but kept the bike from charging my battery. Out in the middle of the Everglades, battery died, took out the ground , retwisted the wire baxk to the one in the plug and taped it and my battery sparked right back to full batt...... Is there something i did wrong? Has this happened to anyone else? Why is it draining my battery?

You made sure your grounding the ribbed box and not the existing wiring harness right ?

But did you ground the box or the wire that you cut that used to go to the box ?

thats the rectifier, the part you are grounding. the budle of wires plugs into that and then you add/replace the ground coming out of the box (the yellow/black wire).
