Hello!
I would like to put my 696 to bed for winter this weekend. Can someone please give me detailed instructions on how to fog the engine?
Thanks in advance for your patience and help!
Go to store, buy fogging oil.
Read instructions on can and execute them.
Profit!
Really it's not much beyone pulling the plugs and spraying some oil down into there and spraying a bit on the plug before your replace it.

I have the fogging oil. I have read the instructions. The part I am unclear on is turning the engine over afterwards to distribute the oil. Can you elaborate?
Pull the plugs and spray oil into the cylinders. Dont replace plugs. Crank the engine over a couple times. This coats the cylinder walls with the oil. Spray once lightly and replace plugs.

Thank-you! I've never done this before so I just wanted more detail.
YOu can turn the engine via hand turning the rear wheel - or a quick tap on the stater. If you've got a newer Duc with the stepper style starter, jsut do it my hand

OK, sounds good.
I don't do it that way.
I have the engine running and spray the oil into the carbs/throttle bodies and keep going until the exhaust is smoky.
Then I shut it down.
It's the way Bruce told me to do it so that's how I do it.

Sorry, but how exactly do I do it that way?

There are two ways.
If you still have the charcoal cannister on your bike you would have to access the throttle body opening in the airbox.
If the canister has been removed normally the rubber lines going to the manifolds are joined and you can spray the oil in those tubes.
It is important to coat the valve seat area.
I had a corrosion issue on my bike that required disassembly to remedy.

I will check that out. Thanks!

This is how I do it as well. Intake runners and valves need to be coated in addition to the cylinders. After I stall the bike out with the oil I pull the plugs spray some in there and cycle the motor.
The directions on the can are designed to fog two stroke motors where you don't need to worry about valves.

DP, was this from winter storage? What happened and what was the required fix? Can you go into greater detail? Thanks

I know I still have the charcoal cannister. Can someone give me more detail on how to access the throttle bodies that is specific to the 696? I have very little mechanical knowledge/skill, but I want to learn.
Take the cover off of the emission canister. Once exposed, the tube on the top left, which is skinnier than the other on the top, is the one leading to the throttle bodies. Inject into this tube to fog as described by ducpainter. This is effective since this tubes sole purpose it to bring exhaust vapors caught by the canister back into the throttle bodies.
The clutch hose is clipped to the cover, so be aware of it when removing and re-installing.
PM me your email if you want a picture of emission canister removal and tubes.

+1. Of course since my bike is only down a few months at a time and garage stored I just squirt some oil in through both plug holes, crank it over a few times, re-install the plugs, and call it good.

I do mine this way except i just kill the motor by flooding the carbs with fog oil. Haven't done an EFI motor yet, but I guess it is coming.
However, I wonder how this might affect later models with a catalytic converter.

As far as we know it was. I'm wondering if ethanol fuel has something to do with it. I know motors that run race fuel need to be fogged after each running if they sit, and unfortunately my bikes sit for extended periods.
It showed up this spring. I had ducvet do my service and the vertical cylinder showed something like 60% leakdown.
The exhaust valve was badly corroded. It required removing the valves, wire brushing the valve and seat, and re lapping the valve.

I don't think the catalytic converters are all that fragile. If the fogging oil contained heavy metals then yeah, maybe a problem. I think that the cat will heat up and burn off any oil soon after starting. You can put this info in your file of infallible facts you picked up on the internet. :)

OK, so we fogged the bike as directed. The only thing we are having trouble with is getting the hose clamp back on. Is there a special way to do this, or is there a special tool we need? Thanks in advance for your help!

I'm pretty bad at winter storage precautions, but based on your experience maybe I should take it more seriously.

You should. Ethanol has made it even more critical to put things to bed.

Those clamps squeeze back together with pliers.

OK, thanks. That is what we were doing, but couldn't quite seem to get it fastened again.
