I am right there with you on the heat, Brian(heat is the enemy), though I have no aversion to any of the "f" words really. :)

Adapting the Kyosho spur is pretty easy - a few minutes and a steady hand on the lathe is all it takes. It is tedious, though(and if you cut too much, the gear is junk - this is why I prefer cnc - the machine doesn't get distracted and make mistakes). I guess a brass spacer could allow use of the stock bearing as well(similar concept to the bore reducer). Maybe I am making it too difficult here. I wanted a custom spur(hopefully a few teeth options as well) for the best fit, but the Kyosho spurs may be the easiest and cheapest way to go.
