Oil injection

[roostafish]

Please, nobody shoot me, but how about this; Why do we not have oil injected off road two strokes? I just bought a 50cc oil injected quad for my son, and it doesn't smoke one bit at idle, and smoke is barely visible when he really gets on it. Wouldn't that be great?! I'd love it, if there was a little oil tank on my bike to fill and watch the level on, and just put straight gas in the tank, with the side benefit of less spooge dribbling out of the exhaust. Why not? What do you all think? The unit on my son's quad looks very simple, and it injects into the intake as it goes into the cylinder. I'll bet I could retro fit one, but would that make me a throwback to the '70s? I remember my dad's ancient yamaha 175 enduro with oil injection, and when I was a kid, I thought it was cheesy, my bike wsa cool 'cause I had to premix.
