Did more testing today, ended up at signature jetting. Runs great, no issues. I get missing at WOT, tried MJ from 158 to 172. All jets the missing begins at 55 MPH in 3rd gear, stock sprockets. It has to be hitting the rev. limmiter. Never hit it before. Tried 158 and 172 MJ back to back, 55 MPH the missing starts. With the 165 the 1/4 to 3/4 throttle are better, also hits the limmiter very easily. I will start a new post to see if 55 MPH in 3rd is it. The difference between the 160 and 200 MAJ is so small that I can't decide. The 160 is in it now so I will leave it. You run the open pipe so a 168 MJ may be best. Think you will like it.

38PJ 1.0 turns 65PAJ EKP#3 152MAJ (6K-10Kft) at 60-100 degrees
38PJ 1.5 turns 65PAJ EKP#4 155MAJ (6K-10Kft) at 30-60 degrees
I got so much more bottom end went to a 15 tooth front sprocket, still tractors like a John Deer and can do near 100mph in fifth gear.

As a matter of fact, out of curiosity, I also procurred the JD triple taper needles to compare against what I'm running currently. If they run better than what I'm used to running (which I'm sure they will), then will I be switching? Heck yes! Faster...faster....aaaaggghhhh!
