My bike is 100% stock and once above 1500-2000rpm it will pull like a tractor. My FI glitch is throttle on/off, not a flat spot/dead spotwhich I think you are describing.I am guessing fuel delivery, not mapping so much. Before you spend the money on aPCIII,do yourmaintenance stuff like plugs and whatnot first.
Good luck, keep us posted.
The bike is stock except for 2 components, a Yoshi slip on and a K&N Filter. IS it possible it just gets to much air and needs to be remapped?
Good luck, keep us posted.

lol..
I mean, "lol!".
Sea foam is a fuel system CLEANER, not STABILIZER.
The bike is supposed to run 86+, meaning 87 IS PERFECTLY FINE. Do you have an engineering degree? If not, listen to the people who do, that specified 86+ and work at Honda. You might consider moving from station to station (pick stations that are more active, since the gas has less of a chance of being "bad"), but leave the octane alone.

Yeah try another gas staton 87 wont hurt anything its perfectly safe. I would go ahead and give it maintence as well plugs filter oil change ect. Another thing dont listen to your friends because they sound like they have no clue what they aretalking about. Someone on a gsx-r 600 talking like they know something. lol If they did know anything they would not be on that bike.

if you know the grand scheme of things in terms of mechanics of a vehicle from my knowledge i've always known that if it starts to bog at low rpms i would agree that due to the free flow from an exhaust it would cause that. the motor on your bike needs a specific amount of back pressure which alot of pipe out there dont hold up to the specs, which is where the pc3 comes in. the biggest problem with an added pipe is the difference fuel/air mixture and how it will be affected by the pipe. be sure to get a pc3 and have it correctly dyno'd to a specific map to make sure it's not running too lean/rich for the mixture. and also, unless you have an added sprocket (similar to advanced/retarded timing) you dont really need to have 91+ octane. if you read on wikipedia on what octane is and what it does to a motor, you'll see that it has more to deal with combustion and not the burning gas.
