Yes, John999. You can disable the oil pump and premix. Most of the road racers in the '70s,when I did a little club racing, did exactly that. The only real problem is you will have very little oil going into the crankcase on the over-run so there is a danger of seizing when you open the throttle after slowing down. Make sure you are set at a decent tickover and you shouldn't have a problem.

I used to run a Wartburg car which had a 3 cylinder 2 stroke engine, I used to put the oil in the tank prior to filling at the recommended ratio, I ran this car for 13 years with no problem. I think what you have is a seperate tank delivery system where the oil is kept seperate. I would think that if you did away with that and just added it to the fuel like I did it should be ok, the only thing would be to get the correct ratio.
