Still at it.....Cleaning the carbon off my heads & pistons, would Seafoam penetrating/cleaner or carb cleaner hurt anything such as valve seals?

dont know bout seafoam but carby cleaner will work, you can also get carbon cleaner an an aerosol and use those green dish scourers

Used it in metric bikes all the time. It was a life saver on a couple of them. Got 4oz in Harley right how, but won't know if it helped til first startup in spring. I have had such good results with Seafoam that it hard to let it go.

Take care and ride safe eh!!

I was wondering about using the cleaner not only on the combustion chamber, but also around the valve spring area. I want to make sure everything is super clean before it goes back together. Is there any rubber seals that could get damaged from using those cleaners? Thanks.

The Seafoam is a good product for removing carbon /freeing up stuck rings - can use it in the fuel tank or oil , will remove carbon if sprayed into intake ,
use it all the time in automotive to clean high milage low maintance vehicles with carbon / sludging problems,

I use Seafoam in the gas tank ever other month. Don't know if it helps, but so far it hasn't hurt anything.

Long reply but here's what I know about SeaFoam (from the internet, of course)

Sea Foam can be added as a gas or as an oil treatment. It is designed to remove buildup in your engine over a period of time. You add the Sea Foam additive and then change oil as per your normal oil change period.
Here is a Harley Davidson discussion from another site info.


SEA FOAM MOTOR TREATMENT for Gas Engine Applications

100% Pure Petroleum
Use in All Engines in All Seasons
2 Cycle, 4 Cycle, and Diesels
Treats 3 Critical Areas: Gas Tank, Fuel Systems, and Crankcase

* Cleans fuel injectors
* Cleans carburetor jets
* Cleans carbon
* Stabilizes fuels
* Upper cylinder lube
* Removes moisture in fuel
* De-icer
* Frees sticky lifters
* Frees sticky rings
* Removes moisture in oil
* Cleans P.C.V. systems
* Cleans catalytic converter odors
* Oxygen sensor safe


How Many Mechanics Use SEA FOAM In Tune-Up of 4 Cycle Gasoline Carbureted or Fuel Injected Engines
Autos, Trucks, and Tractors

1. With engine warm, slowly pour 1/3 to 1/2 pint through carburetor or throttle body throat. (If vehicle is port injected slowly pour SEA FOAM through direct manifold vacuum line that will feed all cylinders, possible sources are P.C.V. valve or brake booster line.) This will pull SEA FOAM down on top of the pistons and to the back of the intake valves to dissolve carbon. Turn ignition off. Restart engine after 5 minutes. If severe carbon build up is apparent, use more Sea Foam as previously directed. Make sure exhaust is well ventilated when using Sea Foam in these various ways as fumes will be extreme for a short time.
2. Pour 1/3 to 1/2 pint into oil crank case to clean rings, lifters, dirty parts and remove moisture.
3. Pour 1/3 to 1 full pint into fuel tank to clean injectors, carburetor jets, fuel lines and remove moisture.
4. Immediate Results: Smoother idle, increased R.P.M.'s better throttle response and improved performance. See label on can for detailed results for use in each area.

FUEL TANK, CARBURETOR, INJECTION and OIL CRANKCASE.
For Peak Performance, Use SEA FOAM Every 2,000 to 5,000 Miles

* A 100% pure petroleum product for use in all gasoline and diesel type engines, both 2 and 4 cycle. OXYGEN SENSOR SAFE.
* Cleans dirty engine parts internally by removing harmful gums, varnish and carbon. WORKS AND PERFORMS INSTANTLY.
* Removes moisture from oil crankcases and fuel tanks.
* Stabilizes and conditions fuels. Use for engine storage.
* Cure hesitations, stalls, pings and rough idle due to carbon buildup.
* Helps pass emissions test. EPA Registered.

When Used Thru Injection or Carburetor

* Cleans carbon build up
* Cleans intake valves and pistons
* Gives smoother idle
* Cleans catalytic converter odors
* Cures hesitations and pings
* Restores power and pickup
* With warm engine running, SLOWLY pour 1/2 pint through carburator, throttle body or direct manifold vacuum line that will feed ALL CYLINDERS. Possible sources are P.C.V. valve or brake booster line. Turn ignition off. Restart engine after 5 minutes. Be sure exhaust is well ventilated. Fumes will be extreme for a short period of time.
* For use in injector cleaning machines, use 50% SEA FOAM and 50% fuel.
* Fill diesel filters with SEA FOAM to clean injectors fast.

When Added to Crankcase (Oil)

1. Frees sticky lifters and rings
2. Increases R.P.M.'s vacuum and compression
3. Cleans dirty parts
4. Removes moisture
5. Cleans PCV valve systems

One pint treats 10 quarts of oil (avg. 1 1/2 ounce per quart).

When Added to Fuel Tank

* Cleans fuel injectors and carburetor jets
* Cleans carbon as you drive
* Lubricates upper cylinders
* De-ices and removes moisture
* Diesel full conditioner and anti gel
* Stabilizes fuel

One pint treats 8-25 gallons of fuel (average 1 ounce per gallon).

In Injector Cleaning Machines

Add a 50/50 blend of fuel and SEA FOAM into injector cleaning machine. Run directly through the fuel rails to clean injectors fast. Add SEA FOAM to your fuel tank to clean injectors as you drive.

Sounds like you want to use it as a cleaner not as an additive in a running motor and dont know if it would harden the valve seals or not. The hot tank at your local machine shop that rebuilds engines is the best idea. It will come out looking like it is brand new, cleans everything off even burnt on oil. You will have to lap the valves back in or get them ground one or the other and would be a great time to stick in new seals too since they are not that expensive. Carberator cleaner or a can of spray parts cleaner from wal mart will do a decent job too but it may also make the seals hard and brittle also. Good luck and just some FYI from a preson that has worked on motors for many a years.

BTW seafoam is a great product have uaed it as an additive many times before

Thanks for the info.
