Just got the SX and SRX fogged put away for the summer. When I fog an engine I start it and let it warm up, pull the top off the airbox, spray fogging oil into each carb until the engine wants to kill and all the white smoke is about to kill me, usually spray for about a minute. Next I pull the plugs and shoot some fogging oil into each cyl, about 3-5 seconds each and pull it over a few times. Just wondering how everyone else fogs their engines?
 
If you think that smokes, you should try ATF like NOSBOY recommends !!!

Wow, does that ever stink up the place !!!

But I must say it does work and cleans up stuff too.

ohh good old fogging oil. how do you guys drain your tanks?

Flo N Go for draining. I Fill my tanks right fuel with premium for storage. In the fall I drain it out and put it in the 6.0L Chevy. I've had problems with dry rot so I like to leave things full so no condensation. I usually start the sleds once a month and bring them up to operating temp to burn any moisture out. My sleds are stored right here in the shop so easy access and very dry.
 
really, you store your tanks full? any one else do this? since thier plastic tanks i never thought there was a need, if they were steel this woud be a diffrent story
 
For what it's worth, I've ALWAYS stored tanks full in everything from dirt bikes to sleds. Dump some junk in the fuel. Run it, choke it till you well....choke. Usually have Sta-bil, some Iso, and maybe some Sea foam in the fuel, fog and park. Never fogged the bikes. Usually store stuff in the garage, not outside though.
Really digging on that Mechanic in a bottle stuff. Gonna add that to the cocktail too.
I usually try to use discretion and restraint burning up the old fuel. Try. Doesn't ALWAYS happen, but I still try.

My Dad never even bothered with the fogging, just ran Sta-bil through the system for a whille, and parked everything. ONLY thing we ever had a problem with was one year with a machine with an old diaphragm carb. Diaphragm dried out over a summer the year it was stored outside. No sweat, just soaked the carb in a bucket of gas for a few days, put it back on, and it was good to go from that point on.
He never fogged our bikes either, and we never had a stitch of trouble with any of them.
 
Fill a clear plastic jug 1/2 full (so you can see it) and leave it outside to the temperature differentials and see what happens.
 
I've always fogged the sleds but think I'm just gonna start it once a month to keep everything lubed, fresh and moving. Like taylzee said as long as its brought up to operating temperature the moisture should dissipate keeping the infamous crank bearings rust free.
 
siphon most of your gas out,add a few capfuls of ATF to the remains,shake sled so it mixes.Start the sled with this and warm her up good.Then I would still fog thru the carbs.
A few years back before my rebuilds I was just pulling oil cable wide open,run throttle to keep it going.Do this for around 10 minutes.When I opened up the motors,the cranks where still wet with oil and coated..never had any break downs with these. triples.Maybe it is all a myth about fogging!!
I run the motor to a good temp and then shut of the fuel with shut off valve until it dies.Then I get all the gas out of the tank.I run all my equipment until gas runs out,never want to leave gas in the tanks to turn to slim.. everything starts good with fresh fuel 6 months later.
 
I pretty much do the same as you shagy( with a splash of atf on valved motors). As far as starting it once a month or so and bringing it to operating temp......Guessing theres a reason Yamaha says DO NOT DO THIS, THIS IS THE WORST THING YOU CAN DO.....right in the manual.

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.

Maybe you could explain why? Yamaha says a lot of things, and their not always right, look at the pro action skid for instance, worst engineering ever. I also don't think it says anywhere to add a cap full of ATF to your gas for storage. Different strokes I guess. Also don't tell me starting the sled in the summer will rust the crank bearings because that's a load of crap, if that was the case my dirt bike wouldn't run. Starting once a month is causing no harm, if anything it keeps fresh gas in and all the lubed parts lubed and moving. Seems better than fouling my plugs and gunking up my carbs with fogging oil.

There is no right exact way of doing it that is why we have this forum to share ideas. I have left gas in a sled and ran it no problems 3 years later and also cannot start a motor because gas was sitting for only 2 months. The important thing is to try what people recommend here so you can see what works for you. Ask questions is the only way you will learn.

Exactly what I'm doing. It was implied starting my sled once a month was a terrible idea and would destroy my sled. I'd like to know why. If your going to tell me I'm wrong because the almighty yamaha bible said so at least tell me why so I might learn from my ignorant ways.
 
The starting the sled thing makes me cringe.... All your going is stopping the corrosion for a little while maybe a day at most. Then once the cases cool, it just starts where it left off and eats away at the bearings more and more till ka boom. But I will say it will stop the carbs from gumming. Don't forget your probably running winter fuel in there, and it does not like heat. Do me and the sled a favour, just take the top off the air box and fogg it. Well your in their clean and drain your carbs. Be adventurous! Invite some buddy over, crush some beers well you smoke the neighbours out, Who knows maybe it will be fun! And as for the dirt bike runs fine thing, my buddys 225 johnson powerhead will beg to differ! Lower bearing poof. Plugs are cheap, overhauls are not. Not trying to start a fight, just don't like seeing good mechines blow up because if lack of simple matiance. I learnd the hard way.

So then all winter everytime the sleds not running it continues to corrode where it left off? Why would it make a difference starting it in the summer or winter? Your saying all 2 strokes are designed only to be run during winter months? So long as its brought up to temp it should evaporate any residual moisture. Also the point of starting the sled is also to move the parts that are designed to move relubing everything. You can't just say it eats the bearings where it left off and kaboom, please provide some kind of logical or scientific explanation as to why.
 
Just for the record, I bought the sled in February and have torn it completely apart, rebuilt the entire engine, skid etc... It's not that I'm lazy or don't know how, I'm just not completely convinced that fogging the engine is better. Maybe better than not doing anything if your storing it far away or can't run it every now and then.
