I’m guessing that’s the left hand mirror, I left it a bit loose because I had to fold it every time I put it in the garage to get it close to the wall 🙂, it never folded on me though ,you’re riding it too fast!, just tighten the Allen bolt!, yes mpg is good, I never properly checked what it was doing but well over 50mpg is my guess, told you it got quick above 7k 👍, and let Dave have a go, you’re hogging it 🙂
