Do you have any plug fouling issues with your jetting set up? I installed JD Blue needle clip #4, 170mj rest stock. I went out for a quick spin and ran ok. Then loaded up trailer and went to some trails and right off the bat fouled plug. I'm not sure if the plug was on the brink from my previous jetting or the jd set up did it. I did not have another plug, so I cleaned the fouled one up and took bike out again this time with 165mj and 160maj like in your signiture. Ran good down low then through the mid a little breaking up, and top felt ok, maybe just a little flat. My plug probably wasn't cleaned up to good so I will wait until I put a new plug in to judge.
When I put the new plug in I was wondering if you still use the 160maj with the 165mj because Im debating on wether to go with the 170mj,200maj or 165mj with 160maj. I run pipe uncorked with lid off air box so I can't figure out why my plug keeps fouling. My last set up was eln #3 with various combos of smaller pj/paj and close to stk Mj's. With Jd's jetting 170mj and blue #4 should I even be close to fouling a plug riding aroung 1000ft in Michigan?

I am running stock jetting with the JD blue 4. I forgot to change the MAJ in my sig. (sorry) but its 200MAJ. I rode this weekend, high 80,s and 100% humidity. Had some stalling off the bottom so I went in 1/2 on the fuel screw and it was fine. I have a little over 100 miles on this setup, no plug problems. The jetting is better at 75 degrees and dry air but was not bad when hot and humid. I think the 160 MAJ is to small for the 165 or larger MJ. If is stays hot you may do better with the red needle as Indy said. Also JD replied earlier to a 426 post and recommended to try Red 4 or 5 in the hot humid conditions. I think if you do 165MJ and 200 MAJ, Blue 4 and in a little on the fuel screw when its hot you should not foul plugs, and when the temp. drops to the 70,s hang on. Good luck.
