I swear by it. I'm not a gimmicky guy either as there is plenty of snake oil on your parts store shelves. I've used it in boats, cars and trucks and mostly older bikes. I actually run the tank very low, pour some in while the engine is running until it almost cuts out. Shut it off and let it marinate for an hour or so in the carbs. Fresh gas and restart. It will smoke your neighborhood out but it cleans the necessary dirty bits in the carbs.

Good product.

 

Some times it works and sometimes it doesn't. Depends on how bad things are plugged up or how much the old gas has done its damage.
My neighbors skid loader had been sitting in the shed for 2 years without being run at all. He finally got it started using starting fluid, but it ran like crap. It barely idled and missed like it was going to stop any minute. So I went back to the shop and got a can of Seafoam, and dumped half of the can in his skid loader tank and let it sit at a high idle for about 10 minutes, while we stood there discussing world events (like neighbors do) and low and behold, it reved up and started running like new! The Seafoam cleared up the carbs good and it runs good now.
Now that doesn't always work that way, but it's always worth a try first before you go and tear the carbs apart.
I think it's better used as a preventative procedure instead. Putting a little in your tank thruout the riding season will keep things running smooth and it also works as a fuel stabilizer during the winter months. I've been using it for the past few years and the bike always starts easily each spring, no problem.

 

I use it all the time, I always put it in just before storing any gas engine for the Winter or Summer. My riding tractor, show blower and preasure washer have never failed me since using it.

 

I put it in every gallon of gas that goes into my bikes, lawnmower, blower, etc etc etc

 

Very interesting, I just got a job at advanced auto in my town and have seen it on the shelves and have though about giving it a try, I think I will.

 

Just read the label, you do not want to put too much in at once.

I've used the stuff in my vehicles and bikes. It's good stuff.

 

I use it fairly regularly as a preventive measure.

 

Can't really speak on Seafoam, have seen people use it, I may give it a try later on once more familiar with the bike. Although My great grandfather used Marvel Mystery Oil, so did my grandfather, and so do I. I've seen my grandfather take a goldwing Interstate that was locked down, with the rocker boxes off, a bottle of MMO, and a torque wrench on the crank & plenty of patience the engine broke free and was running 6 hours later. before I rode my bike, did a tuneup wth plugs,coolant,oil,filter,& air filter, I always add 2 caps of Marvel to every tank of fuel, and 2 & 1/2 caps to every oil change. -Joe

 

U can also add it to your oil to clean out any gunk in the crank case.i did and it didnt bother my clutches.

 

Only got another 11 miles on it tonight but I think there is a real difference. Going thru the whole tank of gas will tell me better I think. Wife was behind me in the cage on the way home, she says it stunk. I guess that's expected and just more proof this stuff is working (already). So badly want to go out and ride it some more but with only 250 miles of getting used to this bike, better to wait for daylight. Not to mention if this Seafoam loosens something up enough it kills the engine. I plan on 2 tanks. I think I'm going to try the run it dry, add 4oz, let it sit for an hour when it starts to die, fill it up and go routine.

Now to just find that syncing carbs thread....

 

Shocking. A seafoam thread on Hondashadow.net.....

 

Put it this way, Seafoam will not hurt anything if used properly (according to the instuctions on the can) and will keep things running smoother too.
I don't know how many times I've read about bikes running like crap each spring and carbs being cleaned, etc. because of gunk built up inside them. If Seafoam would've been used regularly, those problems wouldn't have happened. Check your gas filter every season to make sure it's clean too. If the Seafoam does its job, any gunk should end up in your filter. That's what its there for, to prevent that stuff from entering the carbs.
A little preventive maintenance can make the difference between an enjoyable riding season or sitting alongside the road, waiting for help, it's up to you.

 

I use it(or Berrymans) with no problems and my motor sounds great. May or may not have anything to do with it. I asked some time ago the Honda service manager his opinion. He said "seafoam bad, not good for the bike". Guess he would have less business if more people used it.

I put some in my weedeater gas and it starts and runs twice as good!

 

You'll have a better effect on a two stroke ... nasty oil in the gas :mrgreen:
