Flash in the pan gimmick, along with all the others we have seen over the years.

If you're trying to stop sloshing...most purpose built race tanks are baffled though...

Yeah I guess but I dont see any great results happening but I guess if it doesnt work I could use it in a mud racing

Unless the foam eventually deteriorated and coated your entire tank, carb, and all the fuel lines with gunk.

Yes, it''s good in a fuel cell where the potential for fire or explosion exists. The purpose for which it was developed for the USAF.

motorcycle fuel pumps (among others) have a small chamber that acts as an "air-bubble buffer" (like the capacitor in an electrical system), if you will, from the fuel tank itself. The frequency of the sloshing is just not slow enough to cause that small chamber to go dry. therefor, not need for foam, no matter how cheap and light it is- its useless.

...and gravity fed, float-type carburetors don't give a shit what's going on inside the fuel tank. they are only concerned with what's going on inside the float bowl - which, not coincidentally, usually have "baffles" around the main/pilot pickup. ..and again, the sloshing in the fuel tank is at such a high frequency, the float bowl will never be starved for fuel.

...ironically though, if you put foam inside of your float bowl (because you are an idiot), it might take up just enough volume for the carburetor to starve for fuel. hahahah!

Ha thanks I never knew they made it so there was aways going to be fuel there even when the bike was sideways or the fuel was sloshing thanks for the great info

MOTOCROSS ACTION tested this several years ago with mixed reviews. Probably it would do better for larger tanks for desert or distance races where you use more gas than for a moto.

It can break down over time and plug up your fuel filter or carb. I removed it from a used bike and it just crumbled. It was "motorcycle specific" to be used in a gas tank, unfortunately I don't recall the brand. You will never see me running gas tank foam in my bike!

Yup. It works and does what it's intended to do but the retriculated foam still breaks down. I had it in a tank for two years before it went bad. Not worth the hassle IMHO

I had foam a few years back.

It broke down, and little foam particulates were all over inside my gas tank and clogged my fuel pump.

Reticulated foam comes in two different base compounds, ether and ester, and impossible to distinguish by sight. Break down will always occur in the ester base product, not the ether base.

The purpose of tank foam is not to prevent cavitation in the fuel supply to the engine. It is to prevent sloshing that can negatively impact the handling of the bike. Having that much weight up high on the bike, especially liquid weight that shifts around, is not good for handling. In tests, some guys said they noticed no difference or didn't care and other guys said it was a huge difference in handling.

I bought a bunch of that stuff from one of these online car places. I ran it in my super motard it made a huge difference. Added to my dirt bikes too, but couldn't tell any difference. I left it on my old bike for at least 6 years and it did not deteriorate at all.

We used to run it in our 2.5+ gallon tanks. Helped with handling for sure, 15+ pounds sloshing around less was a big difference.

As far as it falling apart or dissolving and causing issues, I don't know, we changed it out about every 2-3 months.

It's definitely not just a gimmick.

We have ether based foam now that is way finer pore structure than before.  Requires a coarser top layer to allow regular refueling speed.  Also a gauge/balance system. 

If you don't ride near your limit, it won't matter.  The difference at 1/2 tank is about like not having your clickers off by 2.  The other benefits are hitting square edges.  Normally the fuel goes forward and then up.  This can delay recovery form a pitched forward condition.  With foam, more of the shock goes into the suspension and recovery is quicker.  The day will come when this is standard on race bikes and sports bikes.  Probably not on trail bikes, but they truly wouldn't notice.

Wash it with hot water and ring it dry with your hands before you use it. That gets most of the tiny bits from them cutting/manufacturing it out. I have seen it blow up more than one car engine from the little bits clogging the fuel filter.
