"The average range is about 140 miles. however, you'll find yourself turning the petcock to the reserve side at about a little over 100 miles"
Though that has happened to me before, it's very rare I do less that 130 before switching over.
100 was a VERY windy when I was a fat b*stard!
Normal is high 120's.
I don't ride slow either.
I like to hear my baffle-less pipes ya see!!
Suppose it depends a lot how you normally ride and the bike set-up too.
