Re: flat tires on a motorized bicycle (do not turn tire inside out)
Flats are no longer much of an issue for me since using tire liners on all of my bikes. I used to get flats every couple hundred miles whereas I have never gotten a flat on a bicycle with tire liners.
I get many odd looks when purchasing tire liners in bike shops. Typically, other customers and shop employees think I'm nuts for adding "unnecessary weight". I think they're nuts unless they don't mind changing flats on the side of the road. The obvious exception is peddle racing where you want as little weight as possible.
Honestly, I might look for very strong tires for my XR80 build. Tire liners are nice but make the tire changing process a little more challenging.
