Fogging engine for summer storage

Actually yes. Letting a engine especially a 2 stroke sit stagnant is really bad its not so bad in the winter because any moisture just freezes, and does not harm anything. Plus 2 stroke oil is thick in the winter and actually has a chance of sticking to the metal I never said anything about them only being run in the winter months....? Its simple chem and common sense that bare metal rusts. And on top it, your crank seals will dry out. quicker. Just to show you how bad bare metal in a engine can get ill post a pick of my yamaha xs 400 bike engine that wasn't fogged and sat with the exvalve open for only 2 and a half years and it was in a "dry" garage
 

Sitting for 2 and a half years is different than sitting for 1 month then starting it. Also your saying 2 stroke oil is thicker in the winter this may be outside of the engine but when it reaches the inside of the engine thats been running the temptature is the same in the winter or summer. So by your own logic because the crank would be hot the oil would just run off the crank and bearings regardless of it being winter or summer. Also the seals are made of rubber they don't dry out. If that were the case how come tires sitting don't dry out, they're made of a similar rubber compound. Also in the tech section of this vary website the procedure for winterizing a sled says to let the sled run and hold the oil cable to full, no mention of fogging. If what your saying is correct and the oil would just run off why is this still in the tech section?
 
Not trying to get in the middle of what's being said, but my yamaha mechanic recommends just pulling up on the oil cable for 5-10mins. She'll smoke good and ya can kill it. Follow the book imo.
 
Stop getting around the fact that its stupid to not fog it or protect the metal in some way during long storage. Also, apparently you have never seen a old tire dry out, go pour some gas on your truck tires and let it sit for a while. Watch the rubber fall apart. Its not the same rubber! you said just shut it off an leave it. Then start it once a month. When they pull the oil cable they LEAVE it all year long after that and don't touch it so their not re introducing moisture into the cases and Their adding extra oil, same effect as fogging or adding motor oil. I'm not saying 2 stroke isn't good for storage at all, I'm just saying theirs oils designed for this purpose which are sticky and displace water. The starting thing is stupid, to me. I'm done with this, do it your way I will do it mine, just don't come crying to every person on here parting a sled looking for bearings or something because of your storage technique.
 
You are taking everything your saying to an extreme, your dirt bike engine bearings rusted because you let it sit for 2 years, the seals will dry if I don't fog, 2 stroke oil runs off the cranks in warm weather but if you winterize the sled via the way in the tech section the oil doesn't run off? I'm not saying fogging is stupid, I'm saying I've fogged sleds in the past and am tired of fouling plugs and getting sticky oil on my carbs, someone mentioned starting the sled in the summer every now and then is bad I'd like to know why with a non jibberish non defensive answer. There are people on other snowmobile forums that have been doing it that way for 20+ years.

Exactly, no fogging oil necessary. Now I'd just like to know why starting the seld until it warms up in the summer months is bad. I don't buy the whole moisture thing as if the engine gets warm enough it should be hot enough to evaporate any moisture thats made its way into the case.

The trick to me is to bring up to temp to burn the moisture out. The doing harm comment posted earlier doesn't make sense. Otherwise I would have to ride my 2 stroke dirt bike everyday so as not to eat the crank bearings.

I agree with the other comment that there is no right way to do things because everyone stores their sleds in different places (outside, inside, trailers, barns, etc...). I store mine in a dry concrete humidity controlled environment. I don't fog. I park them with full tanks, and start them once a month, Bring them to operating temp to burn out any moisture before it starts to rust the bearings. Then in the fall, I will drain the tanks, put new premo in, clean the fuel system and go.

I have a 1997 600 Twin that has over 12,000 on and I have never cracked the motor. Still running strong as ever. So, not to say I am 100% right in my methods, but if I was wrong, I think I would have had to have rebuilt at least one of my sleds throughout my life due to improper storage. However, this is not the case.
 
That was my thought. If you want to fog your engine fine but don't tell me not to come back on the site and whine about blowing a crank. People have different methods to storing a sled, don't tell me mine is wrong unless you have logical evidence that could convince me otherwise. Also saying my crank seals will dry out because I don't fog my engine utter nonsense. If that was the case wouldn't my crank seals be drying out the whole riding season when the engine wouldn't be fogged anyways? In any case I will be starting my sled once a month to keep everything lubed and in motion.
 
I used to start my sleds once in a while in the summer to hear them run but now i just pull the rope a few times and let them rest.Power valves get greasy with all the smoke.

Comparing an apple to an orange. Sunlight (clear jug) will effect fuel in a way that it wont on your black plastic tank. As well as tank is vented for expansion/contraction.

My point was that you can get condensation in plastic. You can get condensation in most any container regardless of color or material. Not just steel. Steel tanks add the rust factor.
 
I've always just poured the recommended amount of sta-bil in with the gas and topped it right up into the neck of the tank on all my recreational toys and power equipment. Never have I started any of them in the off seasons. We still have good gas up in canada compared to what some of you experience in the states. My toys and power equipment always start no problem.

So you just hold the oil cable full open fill and stabilize tank and let sit?
 
its just in hot weather, 2 stroke snowmobile oil is very thin and doesn’t stick to parts as well. in a 2 stroke once that oil film drips off, and there bare metal it starts to rust so slightly. its all additive. i personally do not think the starting method leaves enough oil on the parts. i am more fawned of the one with pulling the oil cable, but the fogger still is the most effective in my books. sorry for the arguing and bitching, its just the way i have been doing it since i first swung a leg over 2 stroke machine many years ago. I’m passionate about this stuff.

I didn't take any personal offence to any of your statements. This is a forum and you can't take things out of context.
Sometimes things get heated, I just keep the fact that I can't see your face and the emotion behind your comment. It makes a guy think a little more before going off.

Sometimes things come out wrong and the way it's taken is wrong as well.
I'm sure no harm done!

You got it! Spray the entire engine and compartment with WD-40 too. The helps to repel any moisture. Some guys use silicone spray. ;)!
 
well I have my fogging oil and silicone sitting here ready to go.Once the threat of the Flood is gone,will move sleds back to shed and summarize them.
 
It's a snowmobile forum in the summer time, what better form of entertainment then two grown men bitching like a bunch of children? Like I said no worries fog away. I've had other sleds but this is my first Yamaha, my previous Polaris' were pieces of crap. I fogged those engines and they died on me all the time (I know Polaris is not Yamaha). So I bought my first Viper in February with 9300 miles on. It was a tad neglected, so I ripped the whole thing apart (engine and all) and now it looks brand new. I honestly don't think I could leave it all summer and fall without starting it up and sitting on it like a giant child waiting for snow.
 
I could write a BOOK on this topic.... Oh thats right... I think I DID !!!! Well,, not exactly,,but,, some think I could.... Look for the ATF posts that I had something to do with.. If you don't learn anything by my posts,, at least it's GOOD READING...
