Seafoam is the wonder liquid. You use it in the gas,diesel, oil, vaccum line like you described... Shoot, the first time I saw it used on my car, my mechanic used it through the vaccum line. I had a bad PCV valve... I didn't when he finished with the Seafoam... From then on, I SWORE by it!(CAT3 @ Oct. 17 2006,22:31) Never used SF like yamahor described, but used enough of it on the cars...d/c a vacuum line holding it into a cup with SF in it, raise idle and let it suck the SF into the engine so it cleans out the crap on its way thru, also pour an ounce into each cylinder to clean off piston tops. MMO I used when I was kneehigh to a grasshopper as well. Put a cap full in the tank to keep the gas from gumming up, in the crankcase to keep oil "fresh" and parts lubed a lil better, or down a plug hole if engine is seized up (unlocked quite few bikes that way when I was a youngen.

I just wanted to know where Busa owners are finding a vacuum line to pour in the Seafoam.
