OI typically adjusts the ratio based on RPMs. Runs leaner at lower RPMs. While it may be 100:1 at idle it'll likely be much higher at WOT.
Since the early 70's I have had LOTS of motorcycles, snowmobiles, and outboards with OI that have worked flawlessly. If the oil tank ever ran low I made sure to bleed the lines to prevent air gaps. Never had a problem.
I avoided Optimax when it first came out (99?) due to it blowing up a few heads - but they got that figured out over time. As I mentioned earlier, I'm currently running a 70hp on my jet that had the system removed when it was rebuilt - but overall modern OI systems are pretty darn reliable in my opinion...
