I've never personally seen an NSR oil pump fail, but it is a mechanical part, and any mechanical item is liable to failure somewhere along the line.

The (well documented) benefit of premix is that you are directly responsible for the consistency of the 2-stoke mixture. The downside is if you hit reserve or run the tank dry whilst flat out in top, NOTHING is pumped into the bottom-end (and consequently the top-end too). The oil pump continually pumps while the motor is spinning and there is oil in the reservoir.

For the road I will choose the oil pump (on an NSR) whenever possible - for convenience if nothing else!
