I'm breaking in my rebuild and it has new OMP lines. I've driven it at varying speeds for about 65 miles and I noticed there is still no oil in the new OMP lines. How long can I expect before they work oil up to the oil injectors??? I expected it by now. I am running a 2-stroke oil in the gas until the lines prime. 90 vert.

 

mine works as soon as I turn my engine on, I see oil going up the line pretty fast, but after that you can't really see it anymore cuz oil will be filled in the tube. but if you pay close attention to it you will see tiny little air bubbles (if it works)

if you're not sure, premix in tank just to be safe, then run it for a bit, and pop open one of the OMP lines on the engine side, if oil leaks out, then it's working.

 

Thx!

 

My oil climbed my lines very slowly at first. Seeing as the S4 is a mechanical pump metered by the throttle position, I turned the OMP lever over so the OMP was full bore while at idle and let it sit for about 10 mins and all was fine.

I was running 2-stroke oil in the tank at the time.

Not sure if the S5 system, being electric, works on a similar throttle-dependent demand method as the S4's mechanical system.
