Engine miss help

[22Dasher]

I have a friend who has I Yamaha and has a bit of miss in it from sitting over the winter, we poured seafoam into it and that helped some but it still has just a slight miss there. I remember reading a couple years ago of another cleaner you guys used to pour in the tank thats a bit better and stronger than seafoam. I tried searching but couldn't find it so I'm here to ask what was the other cleaner you guys ran thru the tank besides seafoam?

Carbed Yamahas are notorious for completely gummed up carbs from sitting with ethanol garbage in the gas.  My wife's V*1100 had to have a complete carb tear down, twice.  No amount of solvent did anything, it would not start or run.  YMMV

Try some Star Tron, sold at Wally World..can find it in the fishing section..

Techron fuel system cleaner, by Chevron, is commonly recommended.

Star Tron is a fuel (ethonal) stabilizer, but not a carb/fuel system cleaner.  Once the carbs are gummed up, I doubt it will help.  I could be wrong.

Thanks guys I will pick up some Techron for his bike hopefully this will fix it.

Then I am corrected.  The very small amount called for per gallon/tank would not seem capable of cleaning the fuel system.  I thought it was an enzyme only to treat/counteract ethanol and moisture in the tank.
