No, but I have used it in vehicles that have sat after some time. It helps remove varnish and is really good stuff. Just dont leave it sit in the tank too long and you will be okay.

Sea Foam isn't a stabilizer, it's more of a cleaning product. Typically, you have to have the engine running to use it. If you pour it into the crackcase (as opposed to running it through the intake), you'll want to change the oil not long after.

I've used it on my car (valves get very dirty on direct injection engines), but I'm not sure I'd use it on a motorcycle with a wet clutch. You're never sure how these things will react with clutch plates. I have, however, seen a few references to people using it on my Ducati forum. But we've also got dry clutches.

tell your buddy- It is a total of 4.0 gallons.. Drain the fuel out, or siphon the bad fuel out of the motorcycle petrol tank- Put fresh fuel in....
And if a concern of disposing the bad fuel, Put it in the fuel tank of your car - with a larger amount good fuel.....

^ Agreed, drain the old fuel out. Or try to siphon as much fuel out of the top as possible and replace with fresh fuel.

Products like Stabil help to keep fresh (or relatively fresh) fuel stabil over a period of time before storage. SeaFoam won't be able to "bring back" the degraded fuel either - it's typically used as more of a fuel system "conditioner" for the fuel system IIRC.

Definitely drain the fuel, but don't be afraid to throw some SeaFoam in there. I thought it was snake oil for years, but have to be honest and say it has saved me some serious work this past spring/summer on getting more than a few rides fired back up. The stuff just plain works. I've run it in all my bikes this year and have added it to my spring startup routine...

I use it and have for many years. The proper use is to spray into the intake while engine is running before long term storage. I do this for my lawn tractor, both boat engines and my motorcycles. It's intended use is to prevent oxidation and tarnish build up by coating the internals. Their web sight is full of uses, if you follow the recommendations above, then spray it into the intake once running it should clean out engine per their web sight.

Guys over on the Goldwing forum swear by it. I've never used it, but I use Stabil and have my tank full of premium fuel when I put both bikes away. The Wing doesn't require #1 gas, but regular goes sideways so fast around here (ok just about anywhere anymore) that I hate for anything to sit for any length of time with that in the tank.

Duct tape can't fix stupid...but it sure helps muffle the sound
