Ok, now that I have your attention the 130 is my best tank. I just made a couple of changes and my 4 week average is 108. Two weeks ago was extremely windy (35-40MPH winds) for several days and I dropped down to 93 MPG that week. The last change was going from a 38 tooth rear sprocket to a 33, and I was averaging 93MPG with the 38. I also changed to a non-O-ring chain. Other previous mods include a 16 tooth front sprocket (from 14), a Scottoiler chain oiler and a jell-pad seat cover. I run 44 PSI for the tires and the jell pad makes a big difference. I also added a rear view camera which is priceless when you are in a tuck. Also as seen in the top view attached I added a tail bag which is a little more aerodynamic. I believe aerodynamics is where the biggest gains can be from here as other treads also get into.
