wow, i just did 100 miles today and got 70 mpg! and thats running 80+ mph, full open throttle at times. i have a cone air filter, open harley exhaust and 153.8 main. i can tell its got no guts in the low, so i'll be getting a 50 pilot jet tomorrow; no fiddling with the spacer yet.
there must be some variable effecting it like topping it off more on the second fill up, otherwise i got the most efficient savage out there
