Has anyone taken the oil injection off there 800 xp and used premix with good results?

I was more thinking about reliable,how many miles since you removed it?I've removed the oil injection on my sled. It's not a performace upgrade, apart from losing say 8-10 lbs. Sled runs just fine though if that's what you're getting at.
the oil pump has a cable that tees into the throttle cable the more the throttle is applied the more the oil pump opens allowing more oil based on throttle position.the oil pump is driven off the crank so mabey rpms has some effect but i would think that once the oil supply was cut of by letting off the throttle it wouldn't get any extra oil.not sure on that.I don't agree that running pre-mix in a snowmobile is more reliable . . . concider this - while decending a steep hill and you have the RPMs up to help slow you down and your not applying throttle the oil injection continues to lubricate the engine based on RPMs where premix relys on throttle position
And I guess we are all assuming that more is better? Also, just because oil is oozing on the crank case wall from the injector doesn't mean it is getting enough air/fuel to actually pick it up and lubricate the motor.
I did the delete because I wanted it to be more consistent and when I went in last time (because my tank cracked) I noticed the oiler cable had backed itself out considerably. I don't want to run it at 20:1 like it was set at a few years ago. I pre-mix at 40:1 and it seems to work great.

Ok but no . . that is exactly how the e-tech engine operates, only intake air and oil travel through the crank case. The fuel is injected directly into the combustion chamber and is never in contact with the oil. This is why the e-tech is such a clean burning engine, there is no fuel to wash the oil away.
I think what snowcatter is trying to say that when you are going down hill and the engine braking is engaged the throttle is closed, yet the rpms are high. In this situation if you are running premix you aren't getting much lube because the throttle is closed and no gas is entering the engine, thus no oil. He also is stating that in this situation with the oil injection that as rpms increase the oil pump will increase the amount of oil it is injecting to correspond with rpms, is this correct????
I thought the oil pump ran solely from the throttle cable pulling it open, and not from rpm's.
So if a guy wants to pull all the oil injection stuff off and run premix what is needed? it sounds like you remove the oil tank and lines. Then there are two nipples on the crank case that currently have hoses routed to the oil tank, and you still need to supply them with oil in case a seal goes out. Is this correct?
I like the idea of running pre-mix so i know exactly how much oil the engine is getting and run more oil, as all the stories of cables breaking etc... scare me.
As for more oil and power it makes more power. Aaen told me that 20 years ago on the dyno the more oil in premix the more HP on the dyno. Kevin Cameron also many years ago did a complete dyno workup on a dirtbike and had the same results. Downside is the spark plugs won't last as long.
