seafoam added now bike wont run under 3000 rpm

Two days ago I added 1/4 of a can of seafoam to my full tank of gas and now two days later the bike is running awful. The bike wont idle underneath 3000-3500 RPM. At speed it hesitates and then kicks.

Could I have clogged the fuel filter or something ?

Any input would be greatly appreciated.

I think you added to much sea foam and now the gas is too diluted. I believe the directions state 1oz per gal. of gas or something like that. My suggestion would be to pull the gas line off and drain your tank and refill with only gas and then try to run it through the carbs and maybe drain what's in the carbs.

What I'm saying is drain out the sea foam gas and refill the tank with fresh gas w/out the sea foam...

The guys are probably right, but I was thinking that *maybe* you loosened something up with the Seafoam and it was causing some problems. But I'd drain the tank, too - that's easier than riding around on a stumbling, rumbling machine to see if some bit of crud works its way through the system.

Thanks guys,

I needed almost 2 gallons of gas so I filled it up and it seems to be running better after a 10 miles.

Hopefully the 2 gallons dilluted the seafoam enough.

I would think it loosened something up and slightly plugged something else in the process too.
But I don't think it'd be due to too much seafoam.
1/4 of a can (about 4oz when guessing at amount used and if it was a 16oz can) is barely 1/2 ounce more than the recommended dose of about 3.5 ounces.
I don't think you should let this discourage you from continuing regular Seafoam treatments. Especially if this is the first time you've treated the fuel system.
Glad the bike is running better.
On a side note, have you cleaned the air filters lately? Dirty filters could cause similar troubles.

A quarter of a can would be 4 ounces which is one ounce more than the 3 ounces one normally puts in. I don't think one extra ounce would be a problem. Most people don't measure, they go by the "glug glug" method. (one glug equals one ounce). I'm thinking the Seafoam knocked something loose, like Cindy said, and it was hanging up on the the needle valve. Something that's cheap and easy to try is start the bike, turn off the gas and let the bike die. Open the valve, let the bowls fill up and repeat. Idea is that the gunk is hung up on the needle and by letting them drop all the way down-they can flush themselves clean. Seafoam dissolves gunk slowly but surely. You could notice a difference letting it sit overnight too. I'd suggest at the next fill up to add 3 ounces of Seafoam and then every month or so. That'll keep junk from building up to "toxic levels" in the first place.

You might try draining the carb bowls. I drain mine after the bike starts acting stupid, surprising how much crud ends up there.
