How many have you used it? I just splashed a bit in my tank and after riding about 20 minutes my effective pull in 5th gear has went from 43ish area to 35. And by that i mean the lowest speed i can be and pull without getting that rough 'THUMP THUMP THUMP' sesnsayion of the engine struggling. And it looks that iv used a bit less gas on my normal work commute.

I don't really see it being that effective. Nothing beats opening the carb and actually cleaning it.

IDK what it does, BUT, it's the ONLY additive that stopped the fuel injector on my backhoe from making a very scary noise.

That said,as Row said, it's not a long term or high ratio good idea.
The guy who rebuilt the injector s told me that Seafoam decreases lubricity
and will hurt the diesel pump and injectors over time. He didn't say
Don't
He said sparingly and short term.
If you have a clogged jet, you'll need tools,not a can of Seafoam.

Snake oil, is snake oil...

I won't say don't,... I'll just say, I wouldn't... ...

And by a splash i mean 1/10th the can if even that much. And as for the placebo effect im only compairing fuel usage and where it pulls at (i tide the same route to work each day 70 miles in total) i didnt get any more speed or accerlation lol. And i do use 5th at 45 (I was wondering if i got it right, i assumed if i felt vibration i was in too low of an rpm for the gear) i went through the gears after i had rode 25 miles and cruising on flat ground it wasnt lugging in 5th gear to accelerate from 45 and upwards it would go steady at 35 without acting like it didnt have power but i dodnt do it for long knowing that these engines cant run at a low rpm like a harley would, not enough oil being circulated. i get a steady 48 mpg on my work route. 38 to 40 if i ride on the interstate doing 70ish. I will return with my results after i get back home and fill my tank up and see if the next few days have a change in fuel consumption and then i will try to pass it up for tesults lol.

I think some of those products are effective at removing deposits on fuel injector nozzles, and also for removing carbon deposits on the backside of the inlet valves.  I don't believe they are very effective on stuff that builds up in the float bowl or jets in a carb.

Techron was the product of choice for the German car groups to remove the hard carbon deposits.  I use Lucas a couple of times a year in my fuel injected cars.  I don't use anything in my carbuerated bikes.

Well it won't make your a$$ smell like flowers or your words sweet... nothing can help that  

and yeah it's expensive, I've started using Beeman's instead.

but it will slick up a sticky slide, even made a fat boy purr... that may count as a low grade magic trick.
