I'm back to 40 or 42 pilot what every came out on a 03( can't read the writting at my age). Went from 132 mains to 125. But added one more shim. It will do 81 mph at 6000 rpm's at about 80% throttel. So I think biger main's. Every thing eles is really good. But frist I want to read plugges. What I'm worried about,if I take my Triumph to Sturgis this year. That's 300+ miles at 80 + mph over Inter Sta. 90. Will I be running lean after 80 % + throttel. I want to run a littel rich on high throttel.Rudy
