I have one. To keep a car healthy, it has to see a redline at least once a day. I make sure of it. I think I kind of learned to do this from my phase 1 motorcycle days (I still ride, but I’m in the phase 2), that 2 stroke would foul plugs if you don’t let it do what it’s supposed to do, which is running in the power band all the time, and occasional redlining would blow crap away.
