Oil level concern/ New Pro owner

[rmscustom]

UPDATE:

Gave the adjuster (3) full turns

Went from 80:1 to 70:1

Checked it over a 400 mile ride

Going to give it another 4-5 turns

2,000 miles on the 2013 -800 still runnin'

Interesting... 13 Pro rmk 3 turns in from stock was about 25:1, 1.5 turns back put me at about 38:1... Difference in trail vs back country miles maybe?

If you drive the sled fairly gentle and not WOT on a regular basis you won't use much oil even if you turn the pump up all the way. The oil pump is affected most by throttle position and not RPM. If you run around at 1/2-3/4 throttle and 7200-7800 RPM your oil usage will be much much less than if you run around at WOT and 8150 RPM.

On the bold,

Fairly gentle?

Sounds like a fabric softener for doing laundry

LOL. Yea, I didn't like the way it sounded when I typed it. I guess my point is if you aren't spending a significant amount of time at WOT you may not use all that much oil.

I am curious about how many turns you got or have left on your adjuster. Most that I have seen only have about 3.5-4 turns till the adjuster screw is maxed out. Seems yours may have as many as 8 turns if I read your earlier post correctly.

Thanks AK IQ Pilot. Everything you said here is spot on and I hope this will end the misconceived perceptions that others have. If any questions ever come up on this subject, it should be referred back to this post. Good job on explaining. Thanks

No, you are not understanding how the oil pump adjustment works on this motor. The adjustment affects the entire range of throttle movement. Just like adjusting the cable on an old style oil pump affects the entire range of throttle movement.

Adding oil to your fuel tank has almost no positive affect on lubricating the motor. At best, it helps the rings seal better and at worst it clogs your injectors and increases the unburned deposits on the top of the pistons and exhaust valves as well as clogging the ring lands with gumming oil deposits. Any oil that may get on the cylinder wall is immediately wiped off by the ring as the piston heads towards TDC.

For discussions sake, lets say your motor is currently consuming oil at 2oz/gal. That is a Fuel:Oil ratio of 64:1. Now you add another oz of oil to the gas tank for every gallon of fuel. Your new Fuel:Oil ratio is 42:1. So now you have a 50% increase in oil usage but not one bit of that oil is being used to lubricate the rotating assembly. No additional oil is lubricating the crank bearings. No additional oil is lubricating the center shaft and waterpump gears. An almost unmeasurable amount of oil is lubricating the cylinder and piston. Most of the additional oil is just fouling the Injector Tips, Piston Domes, Exhaust Valves and Spark Plugs.

Turning up the oil pump is simple but more importantly, it increases lubrication to the rotating assembly of the motor where it's needed most.

The biggest reason these Pro motors blow up has nothing to do with the oil injection anyhow. They break piston skirts and cylinder skirts. All the oil in the world is not going to fix that.

The factory setting, altho seems pretty low, works fine. Without the fresh fuel flushing out the oil from the bottom end, it stays longer down there and does its job like it should. There have been some bearing failures but I think is was either do to an air bubble from not bleeding the lines from the factory or just bad luck with an out of spec bearing or proper bore sizes or crank runout.

I don't add oil and didn't turn up the oiler either. No one I ride with does this either. No motor failures in our group yet.

My fault for sounding like an idiot. i should've posted it like a question instead of misleading others. sorry and no offense taken. Still a little bitter from not having my sled for last 3 weeks of nice riding due to bottom end failing. 2 crank bearing and waterpump gear. imagine that polaris has never heard of a '12 600doing that.

Picked up my sled 1st week of February, has 2,000 miles on it now from 3 trips
Trip # 1- 3 1/2 days- 540 miles-stock oil adj - 80:1 and ran pre-mix (brisk pace ridin')
trip # 2- 4 days- 1,033 miles- stock oil adj - 80:1 and ran pre-mix (ridin' w/psycho team, 338 miles on day 4)
trip # 3- 3 1/2 days- 420 miles- 3 turns richer oil - 72:1 & NO pre-mix (moderate speed ridin')

Not saying I'm the fastest sledder out there, but there's not too many guys that pass me up

Don't do too much "cruisin' part throttle, it's usually idling or flipper to the bar

Dealer did the last oil pump adjustment, didn't see how many threads left, but I have it home now, will be tearing into it soon as I get a chance, and I'll post pics, but looking to go (5) more turns.

Will probably send out the clutch to INDY Dan this summer

Belt lasted 1,600 + miles, same original plugs, dealer mis-diagnosed an occasional 'hiccup" as a bad injector, ended up being a faulty T.P.S. and then I had to argue with the tech to set the T.P.S. properly.
Friggin' dealers.

Overall, VERY HAPPY with the 2013 800 PRO-R

RAN away from my bud's 2011 A/C 800 and barely inched away (several times) from my other bud's Dynoport piped & clutched 2013 Ski-Doo 800

Well after putting a little over 300 miles on the little beast I figured out I must be one of the lucky ones. I crunched the numbers several times and figured my ratio to be somewhere between 40:1 and 50:1. Maybe I'm a lucky one? All mountain riding here.

I have adjusted nothing and have decided to leave it alone.

I just crunch the numbers for 40:1 when I get home and if it doesn't take it all in the oil tank I dump whats left in the gas tank. In the end its getting 40:1 I usually wind up adding 3-4oz to a half tank of gas.

I will probably stop adding oil to the gas though. I can live with 50:1.

IMO, the "oil ratio" is old school thinking.

You don't need much oil to lubricate the bottom end. What you need is a small amount of oil in all the right places.

How much oil does a 4 stroke use up per gallon of gas? Nearly zero. Nothing about motors requires them to consume oil at a particular rate.

It's easier to design a two stroke that burns oil, but it is equally possible to design one that burns very little, it just takes a lot more work.

I hate to defend anything to do with polaris motors, but if this is such a huge problem, where are the sleds with blown bottom ends?

Needing less oil means cheaper running. Not a bad thing assuming it all works, oil is not cheap.
