Just imagine a 750cc YS stuck between your legs in a motorcycle frame. If you think that would work well for a long time well I just wish you luck with it.
You would need a mechanic on the bike and a trash collector following it to pick up the pieces.

Sort of true. I have a Yamaha TZR250 and a Yamaha TZ250. The TZR is about 15,000km between pistons and rings and the TZ is 500km. Full engine rebuild at 1,500km BUT the TZ is an absolute weapon on the track where it's designed to be run. I genuinly thought the YS would run like a train for years, but I haven't been lucky like that. So while Yamaha kindly supplied me with maintenance schedule for the TZ of what to replace and when so I don't have any major problems, I think YS should do the same rather than rely on owners replacing stuff when it goes pear shaped.
I will admit that as a throwback to the older days, I still like to get in one flight before the comp when I go somewhere differnt just to make sure the mixture is OK. I'm sure I wouldn't have to even think about that if I flew electric.
