Seafoam

Postby thefrontsight » Fri Jul 08, 2011 10:56 am



Holy moly! I have an 82 interstate and its got 48k miles on it. After reading this forum, I decided to try seafoam out. I was wondering what a 30 year old bike that had been sitting for quite some time would run like after i shot this stuff down the air intake. At the time i heated the bike up, shot about 10 oz into the intake and ran it for a bit. I then poured about 6 oz into the crank case and after a hot ride, changed the oil.

I cant tell you how smooth this thing has become! Its like a new motorcycle! Im extremely impressed! Thanks again to webmaster and everyone who contributes to this site! You have saved me tons of money and every suggestion you have recommended has turned out amazing!!!

Gratefully
Michael

Yup, the Seafoam really does wonders for these old bikes. It's a good thing to throw in the fuel every once in a while.

The reason why I shot this stuff directly into the carbs after removing the air filter is because I didnt want to be forced to run the gunk in the tank through the carbs. The gas tank has been drained and replaced with fresh gas when I bought it 2 months ago. Since then Ive run only super through it and have 4k miles on it. If I pour seafoam directly into the gas tank, wont any buildup that is still inside the tank run through the fuel lines and foul the carbs?

Its running really good now...and maybe needs a slight sync...thats it.... so I dont wanna wreck it.

evey time you start the bike up the gunk as you call it is going thru your fuel system.
If you feel the gunk is really bad get a piece of fuel line and install two clean filters one right after the other to hopefull catch any really bad gunk. then seafoam that tank. once you get it all cleaned out change filters back to single filter and you wont have to worry about the gunk.
By the way you dont need to use super or premium fuel these old bikes run great on regular fuel just fine and my '82 has 82,000 miles and my '83 has 84,000 miles.
I just wonder why Honda doe not mention using Seafoam? OH! They would lose so much money repairing things that can be fixed by seafoam cleaning!

I've been riding since 1974 all sorts of motorcycles. I live in the cold north east so I put my bike up in Late Oct. and bring it out in April. I have never done anything to the fuel or gas in any of my bikes and have never had any fuel or carb problem because of this. I am a little leary about putting stuff in the gas tank or crank case that wasn't ment to be there. I have never even use stabilizer. See I probably didn't even spell it right. But now I bought an 83 aspencade with 63000 miles on it. Should I or Shouldn't I. I runs like a top now.

There's nothing in Seafoam that will harm your fuel system, short or long term - and it can be used as a fuel stabilizer. These bikes WILL get gummed up carbs if you let fuel sit in them, and a dose of Seafoam often as not fixes up hesitation or missing.

I run seafoam in EVERY tank of fuel, now the fuel system is very clean, bike runs perfect , and the seafoam conteracts the effects of ethenol in the fuel .plus riding on October, one never knows when it might be the "last" ride of the season. thus I am always stabilized.( well the bike , not me hehehehe)

I have used Seafoam in the past, but now only use it before I put my '82 Aspencade to bed for the winter. I always felt that the Seafoam made my engine run warmer even when carefully measured at the recommended rate. How does it work? My guess is that the Seafoam would dissolve the "gunk" in the carbs and allow it to pass through and be burned, and it would also heat up the upper cylinder enough to get rid of any carbon deposits. Am I right?
I've never used it in my crankcase (yet) but kept it in the back of my mind to try it if I didn't like the MotorKote I added.

Seafoam has been around since the 1930's. Its actually a petroleum product. It will not deteriorate your seals, it cleans as git goes. Seafoam added to gasoline, will keep the gas good for over 2 years. Ive been using it on my 80 GW for the past 4 years now, no issues, just improvements. Liquid Gold!

I addd it to the crankcase, drove for about 100 miles, performed two oild changes, to ensure that I got all the residual out. You wouldnt believe all the emulsified sludge that came out of that case! Wow!

Yup, me too. I change my oil more frequently than the maintenance schedule calls for, so I figured my crankcase would be fairly clean. I did an oil change on my 1100, added Seafoam, ran it for 100 miles, then drained the oil - and what came out was a horrible grey color with lumps of black sludge in it. Amazing!

Has anybody checked to see maybe that the sludge isn't aluminum sludge. LOL, I still ain't gonna put anything in my case except oil or gas in my tank. Never have never will. Never had a problem.

It's not a bike, but the hydraulic tappets on my ford expedition started rattling a little bit, Ford said it was probably dirt stuck inside the hydraulic adjusters and they wanted $1100 to change them out? I have only ever run this car on Mobil1 synthetic with genuine Ford oil filters so I can't see how dirt got in the adjusters, the car has done 63K miles. As I have seafoam for the bikes I decided to put a dose in the engine oil as recommended.. Within 4 minutes the adjusters went silent and it starts up beautifully with no odd noises. I am thinking of driving about 400 miles (to give the sea foam a good chance to clean everything) and then give it an oil change.. All I can say is a $7 bottle of sea foam just saved me $1093!! Seems like a bargain.. I will definitely add it every 20 or 30K miles in my engine oil prior to an oil change, just to clean things up..

Hello!
Kinda a different subject-but I read that 10% ethanol in gasoline reduces power by 30%. 30% ? ReallY ? So we are loosing 30% of the possible power of our bikes by using ethanol gas? That seems like ALOT of lost energy. If I filled with the almost extinct "pure" gas- would I feel much of a difference in the response of the bike? Regards, Johnyy

Only if you believe what you read. If running high-test (pure gasoline, usually) added nearly 50% power, who would buy regular?
Methinks the truth might be 3%, not 30.

Perhaps a confusion between gross energy content of pure gasoline and pure ethanol?
THAT I could certainly see being 30%, but offset by the increased octane of ethanol, if the engine is tuned for it.

I (respecfully) disagree, I cant imagine that high test is pure gas, or that it adds 50% more power. I have used high test-and I didnt see any increase in power. Regards, Johnyy (one thing I learned in life- dont belive everything you think)

O.K.
I misread-not 50% more power-it was only as an example.Still I doubt that high test is "pure" gas. Is there a difference in performance betwen "pure" gas and ethanol gas? Regards, Johnyy

No ethanol added (locally, anyways) to premium fuel. Must be different where you are, only you* would know.

*Edit- Or I would, on a simple google search. All Minnesota gas is at least 10% ethanol. Interesting.
Canada retailers have to average 5%, in overall sales.




(30% reduction leaves 70%. You'd need to add nearly 50% back (of the remaining 70) to get to 100%.)

Ethanol has less energy content per volume.

Ethanol has 2/3 the energy content by volume of gasoline. So gasoline with 10% ethanol has 96.6% the energy compared to regular gasoline. At 15% ethanol, that goes down to 95%.
