Bogging down when full throttle

I have a 2002 gsxr 1000 .... under full throttle it boggs down like its not getting gas. Adjusted tps and also tried disconn tps (Dont recommend doing...Im not that again) Does anyone have any suggestions on what they think problem may be? No f1 codes come up in dealer mode.

check your spark plugs and air filter first if they are clean then you may want to do a little spring cleaning on the fuel injectors that should take care of it my 05 750 did it and i changed my plugs filter and cleaned the injectors and its never run better

2002 Gsxr 1000 throttle delay under full throttle

The only mod on my bike is a Yoshi tri oval slip on. No power commander. Im debating taking it into dealer but I have heard all kinds of horrible stories about dealers replacing stuff that does not need done and repair bills running into big $$ for simple fixes

Then only thing left is to check over plugs and verify everything is connected correctly. The Fi is only sensor related so anything that is off in that nature would throw a code. You say you have a slip on was the exhaust valve system disconneted?

STV working properly? (Will need manual and volt meter to check) The fuel pump pushing fuel as it should? Will it take 3/4 throttle all the way to redline with no problems? If it's running out of gas, running at high rpm for any length of time should be enough to run it dry. If you simply whack it open and it falls on it's face it might be the secondaries having issues.

I had a similar issue with my 03 600. Turns out the "filter", the screen on the fuel pump with all clogged up. Maybe drop the fuel pump and check it out. It isn't that big of an ordeal maybe an hour or so and you can change the plugs and filter while you have the tank off.

I don't need no instructions to know how to rock!

You need to drop the fuel pump off the tank and then pull it out of the casing it is in and there is a small screen on the bottom of the pump itself.

the spark plugs?

they are easy just pull all the screws out of the top of the air box lid, there are going to be quite a few of them. then you will see a couple electrical connections on the bottom of the air box lid and a couple hoses as well, disconnect all of those. Finally, if you look at the bottom of the air box from the sides you'll see two screws on each side that hold the air box to the throttle bodies, loosen those up some and pull the air box off. You will be looking directly at the coils on the plugs now.

My bike did the exact same thing, except during a freakin race. I changed out the fuel pump, and it runs like brand new.

odd, it pulls up fine for me. you have to have adobe acrobat installed on your computer to view it since it is in .pdf format.

google adobe acrobat and install that and try it again

I had the same thing happen to an 06 600..

It wouldnt pass 8000 RPMs, even with the throttle turned to 100%

IT WAS THE THROTTLE BODIES

So have them checked... Most likely that what it is...

And theres no F1 codes for throttle bodies

So what ever happened with this?

I also have an 02 gsxr 1000 having the same problem. low rpm it pulls an runs great, but it seems in the power ban if I wick it to 100% throttle it imedatly falls on its face. When I roll off a bit the power comes back. It will pull to redline at 3/4.
Iv checked the plugs, all look good. Cleaned the fuel pump screen.
TPS seems to be on point at -C00 at idle (another question about that, while riding in dealership mode the line moves to the top under load, is this normal? Also full throttle while bike is not running moves it to the top)
I have a k&n filter and yosh slip on.
SET has been completely removed except the butterfly itself, however the problem existed before removal.
Iv been researching this and plenty of trial & error with no success.
Any other suggestions??

Did you clean both fuel filters? Low and high pressure?

Next time start your own thread in the tech section rather then resurrecting a seven year old one.

Also, post an intro, with pics of your bike, in the "new members and riders" section.

Thanks, I checked mine and it was all clogged up too.

Had the same problem since I put my bike back on the road this Summer. When I hit about 103-105mph with the throttle fully open it would start to bog down like crazy and stop making power. I bought a $13 bottle of Sea Foam today and put half a bottle into a full tank of 93 octane gasoline. Completely cleared the problem right up for me. I'm going to run the other half through the next time I fill up, but as far as I'm concerned Sea Foam was the answer. Bike rides like new. And by the way I took my bike to My local bike shop and the owner was the one who told me to try this before I spent any money at his shop. He said if this didn't work then nothing would aside from changing parts. A big thanks to CPM Motorsports in Coram, NY for not just changing parts and taking my money like other shops would do.
