Sea Foam in a Harley Davidson

So far I have not see it do any harm unless you go overboard with it.
I only know of one person who followed some bad instructions on a Goldwing Forum and OD'ed his trike to the tune of $3000.00 worth of fuel system overhaul. This gentleman who is a 'Self-proclaimed' Goldwing Specialist/Guru (writer) posted that he (trike owner) must use the full can every other tankful three times and the problem would go away.
Used correctly it gets good results, I'll use it twice a year in the correct dose.
 
If used sparingly it should not be a problem, We have had good luck with this product for years:s

Thanks Jack. I know it's been used for quite some time but CATS on the bike are new to me last year on my 10 limited. I didn't know if they would get clogged up from MMO use or not.

I can't seeing the cat on these bikes having the same long life such as the ones on your cage. Running fuel enrichment is very hard on them. Even the factory warranty is under 20,000 miles for the cat. That kinda says it all. If you live in a state that measures CO & HC, you probably will have problems if the emission spec is low. Bikes may be exempt and have a allowable higher spec. I guess it all depends on the state.
 
I like to use sea foam to de-carbon any engine with high miles. As for bikes I would use caution on the amount used. I know some that use it at each fill up on there bikes but at a much lower dose than is called for. None of us have seen any ill effects as of yet.
 
My daughter's 1999 Honda Accord had the check engine light on for about 6 months now and it wouldn't pass inspection. The code was saying the EGR valve was bad. I heard these valves usually aren't bad, just dirty with carbon buildup so a month ago, I took it off and cleaned it real good with carb cleaner. Put it back on, but the engine light came on again after 30 miles, before we could get it inspected. Saw a video about pouring sea foam directly into the vaccuum line from the brakes, where it will be introduced into the motor and help dissolve the built up carbon, which mixes with gum and varnish and hardens, and plugs everything up. These Accords were notorious for this and Honda even extended the warranty on this problem for up to 80,000 miles, but her car has 160,000 miles now, so it's out of warranty. I didn't feel like taking off the manifold and cleaning it all out, so this morning I tried the sea foam in the vaccuum line. 1/2 can, two different times into warm motor. Let it sit 10 minutes to heat bake and dissolve the gunk. Then ran it hard afterwards to blow it all out. She just called and said it passed inspection and the check engine light is still off. WOOHOO!!!!!! Good stuff. IMHO, sea foam is more of a cleaner where MMO is more of a thinner lubricant, very similar to tranny fluid. MMO is great stuff for loosening things up like sticking rings or lifters, but sea foam or B12 is better for cleaning and dissolving gunk.

I don't know what the specs are in my state, since I'm always in the "state of mass confusion". :newsmile08:

Oh, forgot to mention, I put some sea foam in my weed eater and riding lawn mower, (some in gas and some in oil) and they've never run better.

If you have something that can be cleaned chemically in your engine, SeaFoam is hard to beat. Used in the right doses, it can be used year round. I always double dose my grass cuttin' stuff at end of year. The next spring they all start up as if you had just shut them off. I keep the tanks FULL during storage.
