check your spark plugs - if they are black change them
motorcycles are not designed to sit and idle - the seafoam is not flowing thru the PM ports or the main jets when its idling, so nothing is getting flushed out
with the seafoam in the tank with fresh gas, put your gear on, start the bike up, and ride it. If it will run at all ride it hard, find some hills and climb them WFOpen on the throttle, back off to slow down and open it up again.
The fuel and cleaner needs to be blasting thru the jets to work
if you can get it to go about a mile down the road with the throttle open push the choke in all the way - you should only need it for starting when its stone cold.
If the bike wont run well enough to do this, try turning the petcock off and let it idle anyway you can till the floats run dry and it quits - then pull the gas line going to the carbs off and see if you get coax some pure seafoam into the carbs, using something like a turkey baster and a short hose. If you can get some in there, crank it for a few seconds with the throttle open to suck it into the jets. If it starts up shut it off, and let it sit overnight, then put the line back on the carbs and see if it will run well enough to ride it.
If you can do this you will save yourself alot of potential grief from manually cleaning the carbs - its a task with many pitfalls, and if they have never been apart you will strip out the screws and have to replace them.
If it still wont run then its time to clean the carbs manually, flush out the tank good, get a new fuel filter, and run some seafoam thru the fuel pump - then when you got your carbs manually cleaned there will be no goop anywhere all the way back to the gas tank (to get sucked into your nice clean carbs). You'd be surprised how often people do that.
EDIT: just noticed we were already discussing this in your new member thread - did not realize you are the same person, sorry for the repetition.
