Sea-Foam Here,
Been using it for years....With the shiot gas we buy here in Chicago(Also highest priced) I want some added help....Sea-Foam is my choice!!!!...

 

Seafoam +1

 

another one for sea foam

 

Regular Stabil here. I use 3/4 the recommended amount with every fill up. My bike actually seems to run better since using it.

 

Hard to have one consensus here because of the various blends of gas. I'm between Milw & Chicago and EPA sez we have to run the "oxygenated" stuff here. Total crap. In even a month of dis-use it starts to form a varnish-like junk in carb bowls and clogs passages. I have a CBR crotch rocket, some CB 750s, a 6-carb Valk and 3-carb jetski so I have to be a "little" careful in winter. No probs with the regular Stabil but I'm going to try the other stuff in one of the old CB750s since it's a 2 second job to drop the carb bowls to compare. As mentioned, it's a whole different thing in injected bikes, no bowls, needle passageways etc. and nozzles tend to be self-cleaning. 'member, we're taking a fuel pump vs engine vacuum on fuel delivery. Never used SeaFoam as a stabilizer but heard good things. I've only used it in the oil & gas of snowblowers and similar 4 strokes with valve probs.
