I just picked up 6 cans of it on sale at O'Reilly's, and already had one can. I have used a whole 16oz can in one tank of gas on the Vulcan without any issues. I also pull the fuel lines off the the petcock, drain the float bowls, and fill them up with pure Seafoam every 3 months or so. I turn the engine over with the starter to suck it up in the jets, then let it set for 24 hours, and drain it out. I have never had to remove my carbs to clean them in 72,000 miles.
Seafoam is also an excellent gas preservative. Again, use a whole can in one tank of fresh gas, and it will last over a year. Having gas in the tank makes it easy to start the bike up every week or two if you are storing it for the winter or whatever. Very bad for an engine to sit for too long without being moved.
The only time I have used it in the oil is when I buy a used bike that has not been properly maintained. I pour some in about 500 miles before an oil change, and change the oil every 1,000 miles until the engine is cleaned out and the new oil stays clean for awhile. I usually change the oil in the Vulcan every 1000 miles anyway, and the filter every 2,000 miles, using cheap Walmart SuperTech 20w50. If I'm going on a trip, I put better oil in it, but still rarely let it go over 3000 miles, even with the best synthetic in it. But yeah, Seafoam is some good stuff. And while it is on sale, I'd get at least 3 cans. It's buy 2 and get one free.
I am a motorcyclist, NOT a biker.
