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
How about 81 MPH at 5000 RPM. With a 17 tooth sprocket I could do 80 MPH at 4500 RPM. Just sitting hear thinking(my wife dosn't like me doing that)now that I've got enouft power at start why not try a 17 t agein. Rudy
what type of exhaust do you have, air filter sys, snorkel removed? All this will determine your jetting requirements. Go HERE and click on Jetting calculator
Well I've told it in past but we all sleeped since then. I've got a 03 America with unico air cleaner snorkl in(don't want the noise). Got Harley short muffler with drilled baffel. But I'm pushing a 200 lb. sidecar. Now something you guys forgot to remind me abot the choke. I had forgot about the choke test. Took her out today and got up 80 MPH and no faster till I pulled the chock 85 MPH. That tells me need a biger main jet. Now if it had run worse would have told me that I had to big of main jet. You all remenber the choke cuttes down on air and increas gas flow, Right? Oh I don't know what need jet I'e got in. I changed back and forth so many time. What or the letter on the older thounder bird or the stock america?Rudy
