That is, until I rode my TW in shorts today. What a day, near 80, beautiful riding but only got to go about 15-20 miles. I hit reserve at 91 miles, and after fillup, had gottten like 69.24mpg. My best so far. Had my son on the back for a bit, then dropped him off to put a few miles on myself. Found out a Stewarts shop about 4 miles from my house has ethanol-free 91 octane. That's where I will be filling up my TW and my gas can for my yard equipment from now on...
