To seafoam or not to sea foam
14 Sep 2010 13:56
One small question about Seafoam: Is seafoam safe to use in M C gas tanks after it has been sealed/lined with any of the products for this,do any of these additives have MEK, or anything else in them that would pull the liner loose,degrade it in any way so as to impar the running or life of the bike?

OK, stupid thing for me to think about here but..... Have to go with it anyways :blush: ...
Unless wanting to run a whole tanks worth through the carbs, why not use a external 1/2 gallon - 1 gallon tank instead...
Example, carb sync hanging tank...
Just a thought...:blush:

Sorry guys I went fishing yesterday afternoon. :blush: :whistle: :whistle: The "Seafoam" is fine to use in the lined tank. I however have found new and better products since than. "Seafoam" has changed it's formula over the last few years and is not as good as it used to be. Besides that the price went up quite a bit. I now use the Lucas oil products. For deep cleaning like, I used to use "Seafoam" in the old days, I use Lucas, "deep clean Fuel System Cleaner" #10512. For every day maintenance, which I run in EVERY tank full, I run Lucas "Fuel Treatment" #10003. Personally I buy it in the gallon bottles #10013, because I run it in every vehicle I own, and at all times. I find that the engines run much smoother and give me better gas millage, when I do. I run the "Fuel System Cleaner" in my cars about every 3 months, and every 1000Mi in my bikes. I find the Lucas 10512 product as good if not better than "Seafoam" and quite a bit cheaper.

I use the Lucas fuel treatment myself but did not know there was a "deep cleaning" version of it. It must be doing something because I now leak fuel out of every orifice on the bike. Must've cleaned out the gunk that was being used as gaskets. I guess I should have expected that from a 31 year old bike that in all likelihood has never had a gasket replaced (had 6900 miles on it when I bought it). I don't mind. It needed it anyway. There isn't a piece of rubber in and around the motor that isn't as hard as a twig from an oak tree.

It is relatively a new product. It has been around about two years or less I believe. It retails for $12, but I have bought it for as little as $6. Most of the large chain automotive stores carry it.
