How to fog engine - Polaris 600

[Hoosier]

Do you have to pull the airbox off to fog a Fusion 600? I haven't pulled that off before, but I've heard it's kind of a pain to take on and off. I haven't fogged an engine before either, but it doesn't seem too difficult.

Thanks.

I was told to pull the airbox off and spray fogging oil into the carbs till it dies. Also since you have the airbox off it would be a good time to drain the carbs as well.

I don't have your type of sled, but I run fuel stabilzer through, shut the gas off and run it until it idies. Let it cool off, pull the plugs and fog the cylynders. Tighten the plugs and pull over a couple of times. Pull the plugs again and re-fog just for good measure. Me thinks this is going to turn into another "oil debate" thread.

If you let the engine die first, do you just spray into the cylinders instead of through the carbs?

Hopefully this thread stays positive - I'm not asking what brand fog oil to use.

I just spray it into the cyliders through the spark plug holes.

I really think you need to spray into a running engine thru carbs in order to properly protect the lower end, i.e. crank bearings. Just spraying into cylinders of a non-running motor does not do much if anything for the lower end, IMHO.

I pull air box, and spray into each carb until engine dies or is smoking like crazy. Shut fuel off drain carbs then pull plugs and spray some more fogging oil into each cyl while pulling over slowly. I also stabilize the fuel before starting the process and still siphon most of the fuel out and burn in truck before the next season.

Doesn't take very long and is cheap insurance.

My engine is currently being rebuilt because a rod bearing went bad, so that's the main reason I will be fogging - to protect the lower end. After you pull the airbox, do you just take turns spraying between the carbs until the engine dies?

Yes. Switch spraying the fogging oil into each carb until the engine dies or gets good and smokey.

Stabil and run till warm. Use 2 CANS of fogger , run rpms up so engine won't die so easy. Spray quick shots so engine won't die until smokey, then blast itin both carbs at same time, till engine stahls. Pull plugs and blast the top. If you turn the engine over at this point, it is wipping the cylinder clean IMO, so I do not do that.Shut off fuel, but do not drain at this point. (Drain most of fuel next spring). Be sure to cover intake and exhaust ports good so no debris or varmits can enter.

Next spring will require fresh fuel and a good tank of REGAIN carb cleaner.

I can only speak for Cat triples, but strongly disagree with the above statement. I would pull the plugs and dump a couple oz of oil down each hole. Pull rope real slow, otherwise squirts out the plug hole. After a few pulls, I would pull rope fast. I would add few more onces. Put the plugs back in then pulled rope a few more times.

When it was time to wake the kitties, I'd blow into the tank to make sure the carbs were full (tanks were stabilized). Sled fired in first or second pull and SMOKED heavily for 15 minutes at idle. And would smoke heavily again on the first ride the first mile or so. Don't think that was burning off the top of the piston.

Must of worked, 800t was sold with 16,500 miles and 1000t sold with 23,400 miles and no engine work on either sled. Only time I fouled a plug was when I put 7 gallons of diesel in the 800t. Sled still ran on two and left one heck of a smoke trail from Michigammie to Bruces Crossing.

like stated above I dump oil in plug holes slowly turning over till I have used about 1/4 qt I know the crank bearings are drowning in oil.if for some unseen reason I cant get to sled for a few yrs{god forbid }I know it will be fine

On my 900 fusion. I drain the fuel out of the tank. Then I mix a couple of gallions of gas and stabilzer in a can and put it back in the tank. After I run it for a good 5 min I spray fogging oil in the air intake box till the sled dies. Pull the plugs and spray some in.
