Tried reading previous threads on this,but they seemed to get sidetracked w/o solving the problem,so here goes.My neighbor and I put a Spike a/c on his 2005 Softail,and start to jet it.He's got the Thunderslide kit from Dynojet,and that goes in as well(on previous advice from Harley?).They recommend a stock pilot(45?),and 185 main with his intake/pipe combo,needle in the 4th clip.Runs like crap-starving on top.Now,we're at 5500ft....call Dynojet and dude says "175 main,drop needle to the 3rd clip.Makes sense at elevation.......but doesn't work.Is even worse.Tried all sorts of different remedies,long story short-had to go to a 205 main,needle back to the 4th clip...could still go bigger on the main.Only flattening out a little at WOT now.Does this even make sense at this elevation?Do these things flow THAT MUCH air?Any ideas?
