how many are turning up your oil injection?

[EASY]

The transfer ports are open to the crankcase so when the piston comes down it pushes the air from the case reed air intake up the transfer ports to the top of the pistons. While doing so it also pushes the fuel that the injector sprayed into the transfer port to the top of the piston. So there may be minimal fuel that gets down into the crankcase but very little so adding oil to the fuel will not likely benefit the crank but should give the pistons and cylinders a little extra lube when it comes out of the transfer port on the top. So throttle body injection injects into the throttle body and comes in the crank with the air, semi direct injection is straight into the transfer port and the fuel gets mixed with the air on the way up the port and direct injection is directly on top of the piston mixing with the air right before TDC.

Exactly right........the only reason I questioned vftrader was because he said " no gas touches the crank ''

I never said that all the gas goes down to the crank, I did say some goes there. or in your words " so there may be minimal fuel that gets down into the crankcase " minimal is not none. when the injector opens most of the fuel will be taken up into the combustion chamber, but not all of it!!! yes the transfer ports have to be open for the motor to work. but I was talking about the injector port. If no gas period!!!! is suppose to be in the crank then why is that one open to the crank?? I believe that there is some or minimal gas that ends up in the crank housing, and then mixes with the air and oil following through the transfer ports to the cylinder for the next power stroke.

And I agree that adding oil to your gas will do little or nothing for your crank and bearings, That is why some of us are turning up our oil pumps.
IMO from the wear that I could see on the intake side of my pistons, I will be adding a little oil to each tank too help with any wash that might be happening.
I do understand how most of these motors work!!!! but I wanted vftrader to explaine how absolutly no gas touches the crank, when the injection port is open to the crank. I am always open to learning something new

Turned mine up, also adding to fuel. Cheap insurance IMO.

I turned mine up aaaaaaallll the way -- until only like two threads left on the screw. Then I tightened the jam nut up tight. I also add about an ounce of oil for every gallon of gas.

She's smokes plenty now, which always means good protection in my book.

keep in mind the more you turn the oil ratio up the leaner the charge will get.( If your adding x amount more oil there will be x amount of less fuel in the charge).. That being said I turned mine up to 50:1 and run 150:1 in the fuel with turbo setup . ( extra injectors in the throttle bodys)
I think 70:1 is way to lean...

The guys in my group can pick out my tracks on the hill from the black trail in the snow , turned my oil pump up as soon as i got it from the dealer and add 125ml per tank, does not seem to effect performance.

 

[bowtieboy]

Cranked mine up after break-in. It was about 90:1, now its down around 50:1.

OP, Why not make it a poll ? ...

With all due respect, how would you know if it does, or does not effect performance, if you turned it up before you rode it?
Not being a smart azz, but I wonder if dmj1 has something there.

Turned up my oiler over a year ago, and now she has 2000 miles with zero issues..........so far.

That was my understanding, but I'm no expert on these motors. I too am alway open to learning new things that's why we are here. Would some gas get past the rings? And then in the crank? If not, how much lube from the oil in the gas would lube the bottom ring? I'll ask the Polaris people at the Show in Salt Lake Saturday.

 

[skibreeze]

we've had 3 pros now and haven't had a problem with one of them. I am a believer in oil. gas. and go! people read these forums and turn into snowmobile hypochondriacs.. just take care of it and it will take care of you. I think the actual number of people that have problems with their motors is pretty slim. I dont think polaris would keep putting out faulty motors...

Call me a hypochrondriac or maybe it's just because I've been thru more pistons than I've had sleds, but I call BS about Polaris and not putting out bad motors. The fact that they have made changes every single year since at least 08 in their motors tells me that they have.

Can't argue with that.

 

[troyburt]

i turned my oil screw in 3 turn's tonight with just the hood off!

was pretty easy, but that arm is pretty easy to twist! F**K lol

Can't argue with that.

I second that.

Turned up the oil adjustment the 13 before it was even started Yes it has a 4 year warranty, but just seems silly to not to adjust it correctly when we all know a motor needs lubrication! Many people have done this with no ill effects to performance or runability. But it is your sled and your money.

IMO my riding time (which is short, I work a rotational shift) is way more valuable to me than my sled being busted down waiting to be warrantied mid season. Plus I really hate asking my friends for a tow just because "I think the manufacturer should of had my oil pump set to spec". Do you realize they are only doing this to meet the strict EPA emission standard, not for reliability?

die hard poo,

How many turns did you go in on the screw? Yes it way too lean from the factory.

 

[907assault]

I've never heard of anyone going "too rich" by adjusting their pump. I don't know if there is that much adjustability there.

I adjusted mine as far as I could go. (last thread flush with nut, full nut of lockdown)

I haven't had a chance to put a hard ride on it since the adjustment. So, if I still am not going through oil at a safe rate, I may replace the factory adjustment screw with a longer allen head set screw (rounding the set screw end off first). That way, I will have more room to play with, and a good way to hold better back up when tightening it up after adjustment.

 

[die hard poo]

I adjusted mine to where the notch on the oil pump linkage is slightly above the scribe mark on the pump body. Basically required almost all available threads. This seemed to be adequate. Literally doubled my injection rate on my previous pros. I have to fill my oil container after every ride now . If I went two rides (full tanks plus 2 gal) my oil light would be on...

Could somebody explain how the line on the oil pump is sopposed to correspond to the throttle/arm position?

You can use the forum search or read through this thread.

I didn't line mine up with anything when I turned up my oiler and it works alrighty.
