I took the oil injection off of my quad today. Something dad said was that the system was made to mix 32to1 with a stock engine.When you started modifying the engine wiht bigger pistons, jets and stuff, it coudn't supply enough oil to mix right causing the engine to run lean. Could this be some of the problems people have with it?
 
i think the stock injector system actually runs more like 20-1 and the problem with the system is the plastic gear will fail and then you get 0-1 or no oil at all. running lean doesnt have to do with the oil so much but your jetting however if you mix your oil ratio different every time it can effect it a little and hard to get the jetting consistant.
 
supposedly, i heard, the stock injection mixes at 20:1, way more oil than needed
and we all run 32:1 mix, even in our highly modded engines
