OMP/Premix question
Hey all, I have seen a bunch of ppl talking about using premix and ditching the OMP. But I was wondering if you could use the OMP to pump 2 stroke oil from a remote resivour(sp) so that you could always just keep the little premix oil tank full, and not have to worry about getting the right premix ratio.

It was kind of a curiosity thing, cuz I would think that doing premix in a daily driver, would be a pain in the *** and this way it would be fairly simple.

One of the problems with the OMP/MOP injectiopn is that the oil dribble only lubes ONE area of the rotor.
THe FI spray takes care of this... so premix inTHE TANK is better

Such a hook-up/device is discussed in this thread:

beh! they sell a device for avation for around $100 that mounts under the OMP that has a hook up for a seprate reservoir.
i also heard that the standered OMP does a fine job of oil coverage and the only problem is if the omp stops working. So its best the 'downgrade' to the mechanical style pumps if u have an s5.
your right, trying to drive your car daily and premixing sux! Makes topping off rather hard to do....
check this!

CARBON IS EVIL!! Ok, I've read about ONLY using fuel injected approved 2-stroke oil. Anybody have experience with this stuff...I've read about people pre-mixing and fuel filters cloggin and injectors getting clogged. I plan on running pre-mix on my rebuild.

Just get something that was designed to be run through two strokes with reed valve induction. A reed valve will clog easier than an injector or filter.
OC I considered the aviation mod for a header tank supplied OMP instead of the stock setup. Really, the problem with the OMP is the oil it injects, not it per se. But the evidence of this device merely "dripping" oil into the center of the housing has me tilting toward the hardcore lifestyle.
You know what I am going to do? Oregon sucks in a few ways. You can't pump your own gas, someone working at the station has to. I don't want to have to explain why I need to put a half quart of premix into my car at every fill-up so I devised a plan. I will mount a six ounce R/C model engine fuel tank in my spare tire well with a 12 volt electric fuel pump also made for model use. When I stop for gas, I'll hit a switch and have it squirt the two stroke oil into the main tank as it is being filled. There would be lots of liquids sloshing around and mixing in the process . . . just my crazy idea. I will let y'all know how it works out when I get some $ to fix my messed up engine and get it running again.
I still have to come up with a way to remotely fill the 6oz tank between fill-ups without opening up the tire well. I think I will get a half gallon reserve container and hook up a fill valve to the 6oz tank, using a manual valve and gravity feed.
Sound like a plan?

But something else I though about was jsut having a small pump that would mix the premix as it is pumped into the Intake, kinda like older 2 stroke street bikes. Ohwell thought I had a good idea going but I guess not.

The thing that gets me is that the injectors from the OMP have such lousy coverage.
This is why I'll continue putting the premix in the tank.
In Ontario we can choose between self and full serve. I prefer self, mainly cuz I don't see the point in paying a few extra bucks when those lazy ***** still won't clean my windows...

Yeah I tend to never wash ppls windows, but I definatly would, but the only seven that ever comes into work has a 350 chevy small block.
Back on the subject. From what I am hearing the oil injectors don't really "inject" oil they just drip the oil on the rptors? That seems stupid, I will definatly look into my idea, it shouldn't be that hard. They have been doing that on motorcycles for a LONG time.
