How much 2t oil does your NSR250 use per tank of fuel?

I'm trying to get mine running correctly, but it seems to me that mine uses too much 2T. I'm afraid it would run out of oil before I ran through a tank of gas.

get way more than a tank i have never remembered how many tanks i think 3-4 . Check there is no 2stroke oil in your gearbox the seal on the bottom of the oil pump can fall down .

Yip that was my first thought.
If that seal has dropped out of the bottom of the oil pump, and you have put plenty of 2T oil in, be careful when you open the gearbox cap, oil will likely pour out everywhere if this is the problem.
