I started with 76/83 and the dyno guys said I was lean at WOT. I went to 79/87 and it was too rich at lower end, so I went back to the 76 on pri. I am getting a little popping as Bruce mentions, but I think I just need to tweak mix some. I have a new set up pipes I am putting on it so I am waiting to see what they do before I call it done. I will check fuel pressure though since I think mine runs higher than recommended.
