Oil pump cable broken.

I bought my super 9 used with 6000km.  I have put about 2000km in the last 2 months.  I was removing the mud flap and decided to give the engine a once over functions check.  I noticed the oil pump lever was not moving when I advanced the throttle.  After taking the rest of the body panels off I found the cable was broken about six inches from the pump. 
I had no problems with the operation of the scooter.  No overheating or piston seizure.  Does the pump have a fail-safe? Does it go to wide open if the cable breaks?  Currently I have the pump at wide open with the 6" of cable locked into the bracket. 
With every other oil injection system I have worked with if the cable broke you bought a new piston. I just cant understand how i have not been stranded on the side of the road.  Anyone else have this problem or know of a permanent solution.  If I replace the cable it will more than likely break again.

Replacing the cable is the best option unless you want to pre-mix your fuel and oil.  The oil pump still delivered oil to your engine with the cable broken because it is driven by a worm gear on the crankshaft.  With the cable broken though, it delivered less than it was supposed to.  Basically, it would deliver the same amount of oil to your engine as it would if it were idling.  Typically oil injectors run just slightly on the rich side, so your engine might be just fine.  I would remove the exhaust and look up into the exhaust port on the cylinder to visually inspect the piston, rings and cylinder though, just to be on the safe side.
