Lowedog, Sounds like a stand up triple on your first at bat. Simple base hit clip adjustment and your home. Nice Job... Despite being at similar elevations, with my 68 PAJ to your 100PAJ and my airbox possibly being modified heavier, I cannot get near your results. Time to play the trump card. I installed the RED JD needle (4 position) late this afternoon. I already had a 165MJ installed and decided to start there. Right away I noticed my low end problems are gone and I have a little soft popping with an occasional backfire on decel. I adjusted the fuel screw and improved it somewhat but still backfiring. I changed to a 170MJ and adjusted the fuel screw back in a little. I am real close now and maybe there, I didn't get to ride much after making this latest adjustment. I still may need some tweakin but JD was right on in his earlier post recommendation. I still have a issue of the bike missing when pushed to the peak in gears 1 thru 4. The bike pulls hard and strong up to that point. I may just be hitting the rev limiter because I am not use to reaching peak rev's this quick since switching to JD jetting. Question: What's the major difference or response by going from a 68~70~72 PAJ to a 100 PAJ?
