by putting it in the gas tank, it will run through the gas lines and into the carb, which should clean it out good.
For the crankcase, I believe it's 1 or 1.5 ounces per quart of oil (it says it on the bottle) and just pour it in with a funnel.
I've been using it since i got my quad in april and my oil stays nice and golden.
I haven't taken apart the carb, but it always starts up nice and quick and idles nicely, so i think the seafoam is working

i would think you'd still be fine with putting the recommended amount in the oil. If your worried you could open the drain plug a little to let some out and then pour in the seafoam.

dumb question but what is sea foam and what is it used for???
From the Sea Foam website:

"Sea Foam® is a safe and versatile additive that can be used in fuel, oil or added directly into the combustion chamber on 2-cycle, 4-cycle, rotary and diesel engines. Sea Foam® is a 100% pure petroleum product, so it is as safe for seals, o-rings, sensors and other fuel system and engine components as the fuel or motor oil that runs the engine. Sea Foam® contains NO harsh chemicals. All three types of engines (2 & 4 cycle, rotary and diesel engines) suffer from the problems described below, all of which are addressed by Sea Foam®.

1. Old petroleum residue (gum and varnish) buildup. All fuels and engine oils leave behind residue deposits that accumulate over time. In the crank case, this residue builds up around lifters and rings, preventing them from functioning properly. In the fuel system, residue builds up in the injectors or carburetor jets, on the tops of pistons and on the backs of intake valves. Carbon in the exhaust adheres to this residue and forms carbon deposits. THERE IS NO DIFFERENCE BETWEEN THE RESIDUE IN YOUR CRANK CASE AND THE RESIDUE IN YOUR FUEL SYSTEM. IT IS ALL PETROLEUM VARNISH. Sea Foam® slowly and safely re-liquefies this varnish so contaminants and carbon deposits can be safely cleaned out of the systems as the engine is operated.
2. Lack of lubrication. This can occur in the fuel system as the result of dry fuel additives such as ethanol that actually remove lubrication from the engine components. In the crank case, varnish buildup around the lifters and rings can prevent the oil from properly circulating and lubricating. Sea Foam® contains a high-temperature penetrating, lubricating and cleaning oil that will not evaporate even in high heat areas like the combustion chamber. It is also able to safely dissolve varnish from lifters and rings so the oil can flow and lubricate properly.
3. Moisture. Fuel can absorb moisture from the atmosphere - even more so with the addition of ethanol. Crank case oil can also become easily contaminated with moisture. Sea Foam® fully encapsulates the water molecules in the fuel and oil to prevent phase separation - rendering the absorbed moisture harmless.

By addressing these three key factors that produce premature engine wear and cause many common drivability problems, Sea Foam® can be used by professionals and do-it-yourselfers alike to safely eliminate many contamination and lubrication related performance problems and help prolong the life of an engine. A clean, dry and well lubricated engine will run smoother and more efficiently."

Sea Foam testimonial.

Go to the maintenance section and there is a sticky. I put it in all my Recons. I put an ounce in right after changing oil.

But what was truly impressive was when I dumped a bottle in my 99 Suburban with 190k miles. I put 1/3 in the crank, 1/3 in the gas tank, and 1/3 directly into the engine via the brake booster vacuum hose. What a difference! The engine sounds great. Even if it's my imagination, I don't care but it really helped.

I really did it not thinking it would work, just wanted to see the dang thing smoke to high heck like in the YouTube videos. It didn't smoke as much, but it seemed to help.

If I was doing it, I would probably do it before the ride. You're supposed to add it and then change the oil after the oil color turns dirty looking. Here is what the website says about using it to clean the crankcase:

"To clean built-up oil residues and contamination from the crank case, add 1½ oz. Sea Foam® to each quart of engine oil. Sea Foam® will slowly re-liquefy residues and suspend contaminants for easy removal. Monitor oil for color and clarity and change oil and replace filter when oil looks dirty."

Sounds like, in other words: You'll still need to change the oil, just probably a lot sooner based on its color.

Interesting, I never knew you could just run it in the oil. I'll be trying this on the 420... Thanks!

To be honest, I wouldn't EVER do that to an ATV. I MIGHT try it in the crankcase, if the transmission oil and crankcase oil are separated, but even then, it's not worth the risk to see any benefit. You're risking the clutches for what again?????? You shouldn't have that much gunk in your atv anyway. I think a good synthetic cleans better. SeaFoam was originally designed for Boat Motors (or so I thought).

Just my opinion! Take it or leave it!
