Gorgeous work. The Koso instruments are weatherproof? Recent thread I was reading indicated the Motolanna ones were not, surprising considering the cost. You could have incorporated a area into the headlight bucket for the gauge. They often look very cool if you like that look. Carbon stuff can get very hot out in sunlight...keep that in mind in the peak of summer you may wish to employ a bike cover.
You do very nice composite work.
