I've run the TFI for the past year on my 09 RG. It also has the Ness Big Sucker stage 1, V&H mufflers and stock non-cat headpipe. Quick question out of curiosity... If the red pot is set back too far, would the bike to run lean only at higher RPMs (i.e. above 4000 RPMs) or across the RPM range? Current set up: GREEN - 3:00 (Idles great, solid 1000) Yellow - 3:00 (I'm getting 40-42 MPG) Red - 2:45 RPM - 4:00 I use to have it set at 3:30, but turned it back to 2:45 a month ago to see if I experience any changes in cruising and acceleration. Still runs strong through the RPM range, even above 4000 with the changes. No pinging and heat has not increased from before. Thanks in advance for your comments. Ride safe and have fun.
