So far this jetting is working for me: <cross-posted from jetting database> 5,000+ elevation. Dual FMF exhaust and no emissions. Mains - 155/160 low spd - 42 IAMS - 2.25 turns IAJ - 70/70 Stock needles, 2nd clip. Floats - 3.5mm Seemed to run great. No loss of power or throttle response that I could find. 2nd gear roll-on to 9K RPM and it never felt like it was flattening out. I still needed to open the enricher to start it and it very nearly died when I shut that off after a few seconds. I opened it back up just a tad to let it finish warming up. It was about 70 degrees ambient temp for that. I tried putting it in a higher gear while going slower, maybe 25mph in 3rd gear, and then ripping the throttle open. It didn't bog down like it was flooding. It just kept chugging along with a low rumble. So now i'm wondering if the jetting is still a bit lean. I was expecting the bike to bog down with too much throttle. Also, the IAJ's were at 70 when I got the bike. Should I put those back to the OEM size 50 for any reason?
