I stand corrected. It was something bandied by a lot of folks on the VTX forum, especially as part of the laying up for winter process as a fuel stabiliser.
I must disagree about your alcohol comment however as I find it is great for cleaning my injectors! Especially a nice drop of Jura, or haig
Many of us in the US avoid ethanol fuel like the plague........especially when the bike is stored. We pay extra for non ethanol fuel. So added alcohol to the fuel after we purchased non ethanol is counter productive.
Some regions non ethanol is very difficult to find. As 10% ethanol fuel is mandatory.
They now allow 15% ethanol which most motorcycle and small engines manufacturers have specifically said not to use as the corrosion issues and short shelf live are even worse.
The winter storage stabilizer is another hot or controversial topic. Many prefer STABIL for winter storage.
Just got a CT90 out of storage after 5 years. The tank was full with non ethanol fuel and treated with STABIL. Carb was drained petcock off. The fuel was still good and the bike started on the 3 kick. One small data point, but if that was ethanol fuel there no possible way the fuel would be useable.
In the states when fuel goes bad .........the naptha as some solvent cleaning potential. Often it takes complete disassembly with specific carb cleaning.
Not sure of the three ingredients in sea foam provide for storage protection.......but......that controversial part.
