I dont think it would matter fan or liquid, not sure of the boys age, but when I was young, and dumb, I was aways  on the throttle not matter what! , part of the passage ! many great rides!

Just as you said, up through the 80’s, D to the 303, lunch at Edgewater, 303 to  D123, into Kearney, back to D, back through 80’s and across buck lake, down D to 88, took that out to hwy 11, filled at Ultramar, lake back.   Everything was awesome

Where'd you go, up the 80's to seguin over to sand lake and back or did you loop around through hgr? I know LOB was being run dwight to north portage and possibly staked today. 

550 fan or liquid? id have to assume liquid.  Your son doing all he can to keep up to that 800..😂

Oh, and for those gas geeks. me -f-800  son -550 sport ( carbed)   pulled out both completely full. Stopped for fuel in Kearney, obviously we did the exact same mileage, I took 13.43 litres, he took 21 litres
