Any weight saving from a two stroke is taken up by the extra fuel it would have to carry.
My 200 used to use 10l per 100k on gravel roads taking it easy, my 4 strokes use between 5 and 6 liters per 100k.
Considering 30l was not enough for an FI 450 ridden by a front runner, how much fuel would you need for a 300 2t?
