Ok so i find it imposible to do 70mph for a whole tank i nust cant do it. I live at 80+ with a 50/50 mix of city and highway and im hard on the throttle. So 125 or so miles and im reaching for the fuel valve. For those of you that ”can” behave when do you reach for the reserve?
Same basic results with my 06 silverado too,when riding more agressive i hit the low fuel light just at approx 125-130 miles.
If i ride conservative i can go 150-160miles max before hitting low fuel light where hitting reservae is only a few miles after seeing low fuel light come on.
All the above is whith riding 2 up,stock bags loaded including aftermarket bags on rear luggage rack loaded too along with tall windscreen in upper position for more wind drag too.
I have stock airbox but do have aftermarket Road Burner longshot type pipes and did in fact need to tweak carb
a bit richer in low speed to main
transition to correct a lean cond in that throttle positon area post installing the aftermarket pipes.
