Charon you think your bike runs fine,Put some Sea Foam in it and you will see what running fine is like.

Charon, you have made several valid points & I agree there's no magic fix in a bottle... Period.

Adding Seafoam to a perfectly fine engine will not produce more power. It's not gonna fix a burnt valve or a spun bearing either. It may clean and lubricate some, but is that really necessary? Maybe not, but a lot of folks believe in it.

Adding Seafoam is basically multiplying the amount of detergent that's already in gasoline. No, it's not a fix-all, but I can see where it may have a place when reviving an older engine. Weracerc took advantage of the extra detergent by cleaning out a neglected carb. Much like soaking it in solvent, only the lazy man's way (no offense Wera... it worked!).

I like the fact that you backed up your decision to not use Seafoam with data from the DoD, even if the DoD isn't always known for making the best decisions. Having said that, I wanna share that my father was a mechanic in the army in the 60's & continued as a mechanic until he died 8 years ago. Although it was not "official army procedure" to use additives, he occasionally would dump a cheap bottle of isopropyl alcohol ($.99 rubbing alcohol) into a fuel tank to help clean a neglected carb or injectors. Alcohol also attracts water, so it will help dry out any moisture from condensation or bad gas. An old trick he said he learned in the army. So I dunno, that was an opinion based on 40 some-odd years of experience.

I say... If you like it, use it. If not, don't...

I was in the army so anything the DoD says you can take with a grain of salt.
