Just took a trip from Greenville, SC to Ocean Isle, NC, on my 650 V-Star. Half of the trip was on the interstate. Speed limit of 70, but you know no one in South Carolina adheres to that. I was trying to keep up with a couple cars running 80-85. My fuel economy went to [censored] (27-35 mpg instead of 50). Not upset about the added fuel cost, just curious if 300 miles of this type of riding will cause me long term issues.
