Your dealer doesn't know what he's talking about, seafoam is a great product and won't hurt fuel injected engines. I use it all the time in all my gas powered engines and never had any issues.:bigsmiley12:
After the recent storms and power outages here, I cleaned/fixed 10 carburetors on generators and pumps for friends. Even with Stabil,Seafoam,MMO etc. in the tank they were still plugged up with a "jello" like gum in them. And just think the taxpayers get to subsidize this junk fuel to the tune of .54 cents a gallon...When I have to store an engine for any length of time I either fill the tank with non-ethanol gas or 100LL aviation fuel.
Every time I have been lucky enough to find Ethanol free fuel for the bike I notice a definite improvement in how she runs
What are some of the known effects of Ethenol gas on later model Harleys?
I have a 09 Ultra. I use sea foam and Lucas gas treatments. My Ultra has 30k on it and so far runs pretty good.
Thanks
