How do you get your oil ratio...

I been seeing in these threads that the "oiler" appears to be set way too rich from the factory. Can anyone explain how to get the oil ratio and what ration we should be at. I haven't checked my adjustment on my 09 M1000 yet but I'll bet it's rich also... I read in a earlier thread there are "marks" on the oiler. Are these supposed to be lined up? Thanks..

Most will set it between 40:1 and 50:1. To figure out what it is now you need to top off with gas and oil. Remember how full you filled the tank (usually the bottom of the filler neck) and make a mark on the oil res with a marker. Go ride it for the day then refill both to the same level. You will need to write down how many gallons of gas and how many oz. of oil you put back in. 1 gallon of gas = 128 fluid oz. If you put in 10 gallons of gas and 32 oz of oil take 128x10=1280. Then divide that by 32. 1280/32=40, the ratio would be 40:1

oil ratio

you need to have a base line to start, here's my method.
I fill the gas tank to the bottom of the white plastic in the fill neck. filling it exactly to that spot every time.
draw a line on your oil tank close to the top of the tank, fill you oil tank exactly to that line to start.
now after you ride and time to refill fill your gas tank and your oil tank fill both back to those marks. (record the gallons of gas ie. 5.4 gal.) fill the oil tank using a "measure rite" measuring glass, fill the measure rite to the top ounce line. fill your tank and record how many ounces it takes to fill your oil tank. do this exact as much as you can.
now take your gas ( 5.4 gal. times 128 = 691.2 oz.)
now divide your oil ounces into the gas ounces used. ( 17 oz. )
691 divided by 17 equalls 40.65 to one ratio. this is just an example.
check ratio 3 or 4 times to get a base line before you try an adjust the oil pump. My 09 M8 is running about 24 to 1 right now. pig rich on oil.

How the hell do you adjust it? Do you pull the air box and access that way? I have an m6 that is pig rich...

Pull the belly pan off. Not sure on adjustment.

Does anyone know which is the best way to adjust this pump top or bottom? Where are the marks located on the top or bottom of the pump?

If you have to remove the rod arm from the oil pump the only way to get it back on is to remove the belly pan. But I cannot see the alignment marks with the throttle bodies in place. I know they don't line up with the arm removed on my sled. I had the throttle bodies moved out of the way and I could see that. The mark is about a 1/6th of an inch above the other mark and "I think" this is a "less oil" position because you would have to pull on the throttle a bit to get them to line up??

Adusting oil linkage

You do not need to pull the belly pan, just remove the pipe and y-pipe, open the throttle then reach down with a large flat blade screwdriver and pry the link off of the pump arm, do the same on the top but be sure to have a hold of the link with a set of needle nose vise grips or pliers. The local dealer here is advising 3 turns longer but definitely 2. To reinstall use mechanics wire to hold the pump linkage in the raised position then slide the link down and pinch on with long nose pliers, do not try to pry on or you will bend the pump arm. Snap the top linkage onto the throttle body arm and you are done. One more thing if your linkage has a plastic end do not overdo the lock nut. This sounds complicated but it actually only takes about 15 minutes.:

M8 09' is running about 33-35/1.

He has it right on i am able to do it without taking off the pipe and y pipe just a little bit of creative fingers.

tttt

So what is the best oil ratio to run at, without the chance of squeeking the engine.

They will run at 50/1 with synthetic oil. If you use cheap crap,better make it a little stronger mix. That said I run at 40/1 to 45/1 just to be on the safe side. It will vary with each fill depending on how you are working the throttle. The oil lever should be resting on the pump stop with no tension on the cable when at an idle. If you do major adjustments at one time, use premix at 100/1 until you are sure of your ratio.

Isn't there alignment marks on the pump body and one on the actuating arm?

If you remove the skid plate from the bottom of the sled (T20 and approx 1 minute) you can see two small lines on the front of the oil pump that are supposed to be lined up from the factory. (use a mirror and a flashlight, lines should be even when throttle is wide open, even one line width off is significant) note: proper throttle cable tension is crucial for this to be accurate

Lines being even does not mean that your oil ratio will be right because the sleds are set up for low elevations. (check your ACTUAL ratio)

The BEST way to adjust your oil linkage is to remove the oil rod completely, noting its orientation. Loosen the jam nut and lengthen the rod to lean out your oil pump. I suggest that you only lean it out 1 turn each time run again, and check your new ratio.

Depending upon your dexterity you may or may not have to remove the y pipe to reinstall the oil rod (remember to maintain correct orientation to avoid binding)

There is no automatic oil compensation for altitude on arctic cats. Therefore as your altitude increases and the ecu tells the injectors to use less fuel, the mechanical lever on the oil pump still uses as much oil as it would at any lower elevation............. creating a rich oil situation at that higher altitude.

The higher the altitude , probably the leaner you can afford to go. It is safest to calculate your ratio at the lowest elevation you will be riding at to avoid seizure.

Sorry for being so wordy, but this IS the right way to do it!
