      I started riding motorcycles in 1970, dirt bikes, a yamaha 125 enduro lasted almost two years of hill climbing, and tearing through the woods and hills of WV but i tired of that and i wanted a street bike. A RD 350 yamaha bought by working for a year at a local grocery story provided the funds and and i enjoyed "cafe" type racing throughout all the little twisting roads  that snaked through the mountains and I thought I had the world by the tail until one day i saw this on the cover of a motorcycle magazine. I still have that magazine encased in plastic for all time 
       https://www.motorcycle.com/features/archive-1971-yamaha-gl-750.html

      I worked as many hours as possible hoping to one day own that beautiful motorcycle but finally I got tired of waiting and bought a Kawasaki 900. I thought I'd never forgive yamaha for not producing that motorcycle but I forgave them when the yamaha 1100 midnight special became mine. 
      But I still dream about what it would have been like to have thrashed the curves on a motorcycle, that at the time, was close to 5 years head of everyone else in nearly every way. Just before yamaha decided not to produce a street legal version of the bike, opting instead for the TZ 750 road racer it was rumoured the production bike was going to be a 1000cc two stroke 4 along with reed valves, fuel injection, hydraulic disc brakes and liquid cooling, all this in 1971!...   Sadly my dream never came true but I still have my baby in my dreams.

      Just a warning - testing using a new PSU how not yet tested LED emitters do amperage wise on a Friday evening while drinking whiskey does not render viable results and renders precious LED’s dead. Learning is expensive.

      I'm glad more academics are thinking of Simulation hypothesis in terms of a virtual reality or even video game rather than the ridiculous idea that the simulation must simulate every freaking particle/wave in the entire Universe.
