Seafoam question

I seafoamed my gas today. I put 2 ounces in the 1/2 full tank. The bike is smoking like a hippie. Is that normal?

The first time I ran it through my '83 Nighthawk 750 it did that. May want to hear from some of the others here first, but I think it's fairly normal. The Nighthawk did it A LOT but after it cleared it ran much better.

1985 Vulcan 700 (VN700A1) - 18,960 miles - bought for $600 - was told it only needed carb idle screws and fuel lines to run correctly - it used to start

1983 Honda Nighthawk 750 (CB750SC) - 30,000 miles - 95% fully restored

Sounds normal to me. I put the whole can in a full tank even though it says it's good for a minimum of 8 gallons. I use Seafoam on my truck through the brake booster and she smokes like a chimeney for 15 minutes.

Seafoam is an additive that cleans and not as flammable as gas so that is where the smoke is coming from when using a higher dosage. It also depends on if it is fresh gas as apposed to some that has sat for a while. The other stuff that I use regularly K-100mg doesn't smoke but you can feel a slight difference in how it runs. That has a bit more flammability then seafoam. One thing about using a lot of additives.....You should check your plugs periodically to make sure they are burning good. Sometimes over use of an additive can put build up on them and reduce the burn/spark.

I used seafoam twice on my last bike (500 vulcan). The previous owner did not care for her at all as the leather seats where torn, chipped/peeling paint, and rust on the engine/chrome pieces... So needless to say the inside was no different, when I ran the seafoam I completely clogged up the fuel filter (rusty tank) and must have loosened crap into the carbs as she would bog down under full throttle... I solved the problem by running carb cleaner through the fuel line (should have cleaned the carb) as I had never torn down a carb b4 and was rather bashful... Now that I know how simple it is (have seen step by step guides) I'd have no problem. But boy am I glad to have my newer 04 750 vulcan now! She runs like a dream. As for seafoam, that stuff works great, definately does it's job! Just in my case when used on an older bike it got me into some trouble though saved me from the same problem down the line!

When Chuck Norris heard news of the VN 750, he decided to become one!
