I just did jd jet kit. Did 4x4 air box also removed exhaust baffle. Took it for a ride and it was awsome no problems. I had to wash it because it was caked in mud. Started it and let it run for about 2 min. and then I was reving it up a little and then I noticed it had the slight bog back. Air srcew out 2 1/2 turns. Elevation I'm at is 500' main jet 158 & pilot is 42. 5th clip on red needle. Still have stock filter but plan on buying twin air.
Thanks guys.
