Seafoam fuel stabiliser? - SV650.org

Does anybody use this for preventative maintenance over the less frequently used winter months to stop fuel going off etc? Have read great reviews about it.

Nope, never had any problems with fuel going off over a single winter.

Maybe no problems before, me neither but recently the ethanol content of our fuel has increased. As soon as it leaves the pump it begins degrading, it is corrosive and attracts moisture from the air.

It is not corrosive by itself and will only absorb (not attract) moisture from the air if you allow the tank to breath, to prevent breathing you only have to ensure the tank is full to the brim.

try doing a search on youtube for seafoam busted. its a big huge rip off.

ethanol wont make your fuel go off in fact its the opposite, why do you think people put meths and isopropyl in their tank.

yes you are right about it attracts moisture from the air as its an alcohol but it can only take in so much, it has the added benefit of also removing water from your tank.

brake fluid is more Hygroscopic than alcohol but do you take the brake fluid out your bike for winter?

No but the braking system is sealed so there is no chance of any moisture getting in there.

To be clear here' i'm not promoting it's use, just asking opinions.

It isn't the tank that will be the problem, it will be the carb float bowls. They are vented to atmosphere & contain only a small amount of fuel, this small amount of fuel If left stood for a while evaporates leaving behind a gummy residue that will block up your jets. Try it with some fuel in a glass, let it evaporate & see what residue is left. This is with new fuel, now try it with some older stuff from somewhere & see the difference. The storage capacity of modern fuel is now so bad that even lawnmower manufacturers recommend the use of a fuel stabiliser!!

Seafoam started life as a fuel stabiliser way back in the 1940's initially for outboard marine engines in a hostile environment so i guess that by now they kind of know what they are talking about?

to stop the fuel going gel in the carbs all you do is drain them or take the fuel line off, block it up and run the bike till the fuel in the carbs runs dry.

ooohhh and your brake rez is actually open the the atmosphere via a small vent. if it wasn't then you would create a vacuum as your pads wore down.

Isn't the vent on the top side of the rubber seal in the reservoir? The rubber then deforms to keep the fluid sealed, but the air gets in above the seal and never meets the fluid?
