Are you reffering to the velocity stacks, when you say air filter openings? I've sprayed standard carburator cleaner down there before (while reving the engine a bit) with no ill effect, so I'm guessing Sea Foam is a similar type of product, but without a spray nozzle. Without the nozzle, you might get too concentrated an amount in there all at once, which would probably choke the engine off. You may also free up too much crap in the system which would clog the carbs up more. I once mistakinly tried STP carb cleaner in my tank in a too concentrated amount a few years back. It had the effect of releasing too much crud at one time and the carbs needed to be removed, soaked in varsol, recalibrated and reinstalled. Won't do that again.

Seafoam in the gas. Run the tank partway empty and let it sit for a day or two. Then run it down and put new gas in it. If that doesn't work then it is time for a carb cleaning.
Check to be sure there aren't any critters in the air filter or that you didn't over oil your filter if it is a foam or cotton guaze filter.
If you have a gas filter replace it. Double check your gas lines haven't deteriorted and gunked everything up. Double check your gas tank vents are not clogged.
Double check your throttle cable (s) are lubed so that they don't lag when you roll on to WOT.
Did you have any gas in the tank before you filled it up with the fresh stuff? If so you may want to flush the crud and rust out of the tank. On my Kawasaki Concours there is a little metal mesh screen in the petcock that should also be cleaned but not sure if you have that or not.
If it sat long enough all new plugs, fresh gas, tune up is probably worth while anyway.
I believe if you can't find the Seafoam you may be able to find the Chevron Techron cleaner or Berryman Carb Cleaner. (Techron, Berryman carb cleaner, and Seafoam is all they use at the Concours.org (COG) web forum) I believe the Berryman carb cleaner is found just about anywhere even at Walmart. So is the Techron cleaner. I always liked the Redline SI-1 fuel system cleaner but they now make a motorcycle specific fuel system cleaner.

Well dudes, too much OT at work and the fact that I also own a 2000 Honda Magna Cruiser have conspired against me and I just haven't checked all the things suggested in your replies yet. I have removed and cleaned the air cleaner. That did nothing. I've finally gone through 2 tanks of gas with Seafoam. One thing is for sure, Seafoam does improve overall throttle response very well. For a while there, I thought it may slowly be doing the trick, as I noticed that lower gear WOT was getting a lot better, but still problems in the higher gears. After letting the bike sit for a week, the problem came back in all gears under WOT only. One thing I never mentioned before was that the problem only occured as the RPM's hit 7-8000 plus. Never down in the lower RPM's. I'm guessing that plugs and wires have to be changed now. I don't put many miles on this bike per year as I ride the Magna a lot more. The plugs are 3 years old with maybe 6000 miles on them, but the wires are original. Keep you all posted and thanks again. Keep the sugestions coming if there are any new ones. Oh wait, when I had the tank off to clean the filter, the were a bunch of smaller little filters (sealed in little black plastic boxes) running off of thin foam air lines from somewhere (maybe the low soeed RAM air). How are those filters replaced and how often? They are originals.

Sounds like your carbs are junked up from setting over the winter bro. You should be able to punch it and just go no matter what. I have a 93 900 rr and its carbed and i cab unless i get some bad gas or the carbs get dirty like sitting over the winter can do that. If you dont want to get hosed by the dealer for a carb clean then you mite try a buddy but make sure they know what there doing caz they mite mess them up, Id do to the dealer and get it done right and be done with it. Im sure a carb clean would do you good and new plugs. Uh Huh

The carburetor bowls are like mini gas tanks and if you leave gas in them during storage, deposits in the fuel will collect and harden in the bottom of the bowl, forming a disk of intake-clogging poopiness. They are heavier than the fuel in the bowl and usually stay on the bottom like trolls (gnomes are much cuter and only live in gas tanks) during normal operation but when its WFO time, they jump up and scare away all the fuel from crossing the bridge into explosion land. It's like putting your hand over the end of a vacuum hose.
Fortunately carb bowls come off pretty easily. Turn your fuel tank to off (duh) though some gas will leak anyway. The bowls are the silver bowl-looking cups on the very bottom of each carb. There should be three Genuine Honda Screws attaching each one. All you have to do is unscrew it, remove it, clean it, replace it. x4. Done.
Keep it on a regimen of total fuel system cleaners. Spring for the expensive stuff. Techron kicks ass. And trolls.

I think I have the same issue going on. Where I notice it happening is when I turn the throttle more than 1/4th turn. Usually, that takes it to around 6000 RPMs. I replaced the fuel filter, ran carb cleaner through a tank of gas, checked the air filter, checked the fuel pump, and cleaned the carbs. Just before this started, I had replaced the spark plugs, because previously, they were completely fouled and the bike wouldn''t start. I had also previously cleaned the air filter and re-oiled it.
quote:
Try slowly going to WOT rather than just hammering it. i.e. instead of snapping the throttle open, take 1-2 seconds to get there and see if it does the same thing. In my case, it makes no difference as to how fast I open the throttle. quote:
Sounds like the needles are junked up. I''m take them off and clean them. Sprayed out with carb cleaner while I had the carbs off and cleaning.
The kinds of things I''m thinking at this point would be:
-sync the carbs
-pull the plugs again
-could be petcock screen as mentioned above
Outside of those three things, I think I''m almost completely out of ideas of what could be causing this. Any
further thoughts?
