It's an on and off problem. Sometimes it does it, other times it doesn't. My problem is that even at WOT it won't go past 11k rpm's sometimes. It goes just fine up to about 9 then starts to slow down and falls on its face and won't go past 11. It's so strange and feels so weird. It's like its being held back. I don't think its the fuel filter. Maybe the fuel injection or spark plugs? No idea. help please. 03 600rr 8,000 miles.

Another thread on here the guy couldn't redline his bike everyone said fuel pump and that was the problem. You can research the thread think it was something about not redlining....hope this helps some

i had this problem too, i replaced the fuel pump and the problem is gone. my problem was intermittent as well, however over time i realized it was actually correlated with how full my tank was. if it was full- the problem didn't occur, once i hit one or two bars, i couldn't rev past 9k... i bought a fuel pump from a guy off this forum from an 06 (it's exactly the same) with 2800 miles on it, installed it- and now the problem is gone. i have tested it with low fuel and it no longer does it. normally, the problem seems to start happening around 20-25,000 miles tho- if you research you'll see... so it's a bit peculiar that your pump gave out at only 8000 miles.

do you have a PCIII? are you at high altitude? do you often run your bike with low fuel?

try to never run your bike with low fuel, fill up when you see one bar. when the fuel is low it forces the pump to work harder.

yea the battery can do alot of weird things. my friends GSX-R would start and die. end up being the battery. its weird cuz you can start it and hold the revs up and it would stay on. once you left off it dies til it warms up than it be ok

Yea it has to be the fuel pump. You guys said how it happens on a empty tank and you are right!!! Now that i think of it...i started out with a full tank and it was fine. Rode thru the day and when the fuel got low and it wouldnt go past 11k. I filled up the tank and it would redline. So it must be the fuel pump! Makes sense now. Thanks guys.

I am having the exact same problem. it won't go over 10k at wot, if I back off a hair it will get up to 12k and stops dead there.

I thought it was my battery (the battery was bad, but I replaced it and it didn't help).

It started after I took the bike apart and rebuilt the starter motor. so my next thought is I put something back together wrong in the air box that was messing up air flow.

Keep us posted on what fixes it.

also, does anyone know how the air funnels inside the air box are supposed to go in? are the longer funnels supposed to be on the out side 2 cylinders or in the inside 2?

It's your fuel pump too. Very common problem. I'd even say that ALL the people here that have had a problem with the engine not redlining... It was the fuel pump.

If I remember right...Long ones on the outsides. If I'm wrong... someone let us know.

^^ yea, avoid doing that again if you can. the pump has to work super hard at that point. the more fuel you have, the less the pump gets stressed out.

2003 600rr won't rev past 11k RPM FIXED

I have a 2003 yellow 600rr.
Bought it 3 seasons ago. It was a steal with only 671 Miles on it. The owner was in the service and never rode it. She had the bogging down and power loss issue. Violent jerks, bogs and power loss, etc. Thought it was low gas level as it came and went when I pulled over turned her off and on again, or filled the tank.
Searched and Searched for a solution. Below is a list of the things I did:

Changed Regulator/Rectifier (aftermarket upgrade)
Changed Plugs (iridium/deal spec)
Changed All Fluids (syth oil and honda 50/50 antifreeze)

After reading about fuel pump issues on the net one day I pulled the fuel pump from out of the tank. It was full of rust and mud colored muck. (From sitting all those years) The mesh was also filthy. I cleaned it out as best I could and put it back in. The bike ran better, but still would not rev past 11K. Then I found this post. I decided to change the fuel pump. I found a 2005 pump for about 120.00 on ebay. I put it in yesterday and the rest is history!!! Finally my 600RR is roaring like she is supposed to. I cant' put her down!!

Now me and my b*tch are enjoying this nice cool fall in NYC!!! "Rev Meter, Rev Meter, Rev Meter"

SOLUTION:
CHANGE THE FUEL PUMP!!! MAKE SURE YOU DON'T KINK THE FUEL LINE WHEN YOU DO IT. I LEARNED THAT THE HARD WAY...GOOD LUCK, GOD BLESS!!

Most def a dirty fuel pump. Either clean it out real good or just buy a new one. Make sure to clean the screens at the bottom of the pump. The actual filter is built in the the pump and no way of cleaning it thoroughly. A good cleaning/rinsing it with gas and thumping it with something loosens some of the stuff in it and comes out.

when i took my bike apart in 2011 i took out the fuel pump & cleaned the strainer & the filter cartridge, also cleaned the fuel pump just for good measure.

the thing is it isn't the pump that goes bad most of the time, it's the filter cartridge but you can't buy the filter cartridge alone, you have to buy the whole fuel pump assy which sucks.

this was also a common problem with GSXR 600's (not revving past 9K rpm) & they go about replacing the fuel pump assy so i did my own analysis, jumped the wires & saw the fuel flowing out the hose is inadequate, took out the pump & removed the strainer & filter cartridge & the fuel flow out of the outlet was like a fountain so i knew the pump isn't bad, next i put the strainer on & still the flow was pretty strong which leaves the filter cartridge, when i put it back on & turned the pump on again & sure enough the flow was back down to a trickle.

i tried cleaning the cartridge by blowing compressed air through the outlet but it didn't do jack, flow was still restricted, ordered a new filter cartridge & that solved the problem, engine was back to revving to 15500rpm again.

the thing is the fuel pump & filters on the suzuki & honda are similar except for the fuel sending unit which the suzuki doesn't have, the honda's fuel sender is mounted on top of the filter cartridge which the suzuki doesn't have, if it wasn't for this small difference you could just order the filter cartridge from suzuki & it bolts on directly to our fuel pump assy but having a fuel gauge has its plus too.

Hi guys. Sorry for ressurecting this old thread, my '09 started doing something funny yesterday, she is on around 24 300km and is due for her 24 000km service.

She pulls fine from the lower ranges up to around 11 000rpm, then it's almost like the clutch is slipping and she revs up to about 12 500rpm but doesn't go further.

I'm not sure what the problem might be, would the ECU maybe restrict the revs due to it being due for its 24 000km service? Spark plugs maybe? It feels and sounds like a slipping clutch almost, but it doesn't slip at all at lower revs.

Might be old plugs causing this as I'm yet to replace the plugs as I'm not sure when last they were replaced, but she was still pulling 100% a few ride back. Just now all of a sudden this is happening.

Very confused about this. Hopefully someone has dealt with this before.

Thanks.
