Thanks man I appreciate all the help and moral support. Only had to replace basically the entire fuel system. Let this be a lesson to all to properly winterize the bike. Rust in the tank sucks. Rust in the tank with a dumbshit, like the previous owner, who rides it that way for 2 years is even worse and leads to this kind of crap. I hate to say it but thank god for ebay... Also, I think it is kind of cold to compare me to FocusDave, but maybe I deserve it. Sorry about that and I promise that it won't happen again...

I bought a used tank as it wasn't very expensive. I may try to re-line the old tank when I get some free time.

Didn't sync the old one or the new one. The used one I put on had about 3000 miles on it and was almost factory fresh so I saw no need. The original problem was rust in the tank so this was just the last part of the fuel system to replace.

Around $300 for parts. I did the work myself so labor was free...

Thanks all for the help! I replaced the throttle body and injectors today and the problem is gone! So the total of parts was tank, pump, throttle body and injectors. The throttle body was probably OK but I got a great deal that included the injectors, airbox and map sensor so I just replaced it while I was in there. Thanks again for all the help and I promise that this will be the last time you will have to hear about this!

Put the bike up on stands to change out the throttle body, fuel rail and injectors and the sight glass indicated that the bike was overfilled with oil again. Drained some oil out and the oil smelled like gas. Could be a stuck injector from all the rust running through it over the last couple years, or it could be from my commute downtown and the low rpm riding. Anybody have any experience with this and how prevalent is it? I try to ride to work every day that it is nice out and do end up in a lot of stop and go riding. Sounds to me like a stuck injector because for the oil to go from between the lines in the sight glass to completely full in the sight glass in a few weeks would mean it is dumping a lot of gas. Also, the bike has a leo vince slip-on and no power commander. That wouldn't cause this issue would it? Bike still falls on its face at 10-12k rpm. New injectors, throttle body and map sensor (used) going on tomorrow and now it looks like an oil change as well. I replaced the tank with a used tank from a California bike. That wouldn't cause an issue would it? If this doesn't fix it is anybody willing to help diagnose it for free beer, pizza, liquor, hookers and blow?

I have a brand new sportech v-flow black chrome windscreen for a 2003-2004 cbrt600rr that I would like to trade for a sportech classic dark smoke windscreen or similar. Otherwise i will sell for $50 obo. Available for pickup in Reynoldsburg or will ship. Unleash your inner gixxer with this black chrome v-flow windscreen...

Found a great deal on a airbox, throttle body and injectors for the 2004. Cheaper than cleaning all injectors. The complete kit will bolt on a remove all traces of rust. The bike is inconsistent now. Sometime it misses and sometimes it doesn't. Stator appears to be good as the battery is still fine. Still seems to get 40 mpg roughly so not running too rich. Actually seems to run better when it is warming up, meaning richer than once it is fully up to temp. All factors point towards leaning out on the top end. When colder it runs further up the rev range to 14k. When fully warmed up it starts missing at 12k. Going to take that killer deal on the airbox, injectors, rails and throttle body and complete the replacement of the fuel systems after all that rust. Hope that takes care of it. Only thing left is map sensor and Temp sensor. I know I should do some more testing but the price for all was significantly less than just the injector cleaning procedure and the replacement should be fairly easy. I already know that the map sensor is good after pinching off the vacuum line so that really only leaves the temp sensor as the ECU indicated a map sensor fault immediately after disconnecting the map sensor.

Factory velocity stacks in place and the OEM fllter is in place. Not sure what the deal is....

Thanks for the tip. Crossover tubes there. Bike cruises great no issues there. Only problem now is bogging on full throttle above 10k rpm. Less than full throttle the bike feels great. I might have to have someone else look at it and probably have someone else ride it to compare it to other 600rrs. Doesn't appear to be using any oil and the coolant is a little above the low line and looks very clean. No milkshake oil etc. The seafoam might be causing the smoke so that may offer no clue but the gas smell is there if I am revving the bike a little at a stop. When I replaced the tank it appears as though all injectors are connected. I am stumped. Any suggestions on a place other than the dealer to take it if I can't get this figured out?

UPDATE. Perhaps the bike is running rich. I let the bike idle in the garage and reved it a few times. I saw some smoke out of the exhaust when I let off the throttle. The Leo Vince slip on is a pretty black on the end of the pipe and the wife said she smelled gas in the garage from my reving experiment. The bike still stumbles above 10k at full throttle but takes off if at 95% throttle. I get at least 160 miles on a tank and am averaging 40 mpg so it can't be running that rich. Alo, there is a full bottle of seafoam in the tank right now and that may be contributing to the smoking. I bought it used and was told that the only non-appearance mod was the Leo Vince slip on. This is my first modern sportbike so I don't know whether it has a full exhaust or just the slip on and maybe that is causing it to run a little rich and bog at the top end? Maybe it is the regulator/rectifier? Any ideas. Thanks

Well that pump replacement didn't fix it. May need to have someone else ride the thing. Goes through 10k rpm ok now but still hangs at like 12k rpm at full throttle. Let off the throttle slightly and it will rev freely. Time to check some more stuff. Any other ideas or suggestions for a decent mechanic to fix this would be great. No MIL. No indication that there is a problem other than using full throttle above 10k rpm. Dumped some seafoam in the tank and we will see ho that goes. Battery replaced with brand new yuasa around 1 month ago. Going out of town for business next week so looks like I won't have it figured out by memorial day. One more thing to add. It was overfilled with oil by about 1/2 a quart. That led me to replace the air filter as a precaution and clean out the airbox. Not much oil in the airbox and the filter still looked good, but I replaced it anyway. Thanks

With the new tank/pump it feels like it is bogging above 9k. This is a new issue since installing the tank/pump. The missing and hesitation seem to be gone but now it bogs badly at high rpm at full throttle. If I back off the throttle a little to around 80% it shoots up the rev range and then starts bogging again at 14k. Seems like it isn't getting enough fuel at that rev range. Below 9k it runs great even at full throttle. Getting a 2nd pump right now to test the theory that the pump is bad. 600rr.net seems to have loads of people with the issue and it turned out to be the pump. Plus, since this is new behavior since installing the tank/pump I thought the lines might be pinched but they aren't. Basically I am targeting that which was most recently changed. Thanks

Thanks. The new plugs I just put in are dry and look good. The color is good and everything looks correct right now. Took the tank off again and all the lines were clear, no pinching etc. I am going to take the pump out and check the tank for any debris and try to clean the filter. Then I will put it back in and try it one more time before I call the place that sold me the tank and pump and try to get a replacement pump. Thanks

For those of you that remember the saga of this bike. Bought it in April with 5000 miles on it. Clean title, never been down etc, Leo Vince Slip-on etc. Had some hesitation/surging issues and discovered that there was rust in the tank. Bought a used tank and pump on ebay and installed today. Also replaced the air filter with an OEM one (wasn't needed) and new plugs as well. The were fouled but otherwise looked like they were burning fine. Perhaps a little rich. Installed new tank and pump and put the bike back together. Idles better and the missing is pretty much gone. However, now it won't rev to redline or sometime even above 10k at full throttle. If I let off the gas a little it will rev higher but then starts missing again. I suspect the tank is from a california bike. That wouldn't cause any issues would it? Sounds to me like the fuel pump that is in it is faulty. My old pump is pretty rusty so I am not sure I want to install it in the clean tank. Any other ideas? I am about to give up on this thing and I hate to take it to the dealer.

Roughly translated - THINK you *^&%^%#. She got the point cause she slowly put the magazine away. I also shook my head.

Yesterday at 4:30pm on 670 heading east from downtown. I was in the passing lane and this lady in a civic rolls up beside me in the bumper to bumper 25 mph traffic. She was reading a magazine on the steering wheel and drifting all over her lane. I honked several times before she looked up and then I tapped my finger on my helmet. She slowly pulled the magazine down and tried not to look at me. I couldn't get away from her because of the traffic. When I finally did see her again later on 670 she was reading AGAIN!!! Some people are too stupid to be allowed out amongst other people.

I couldn't tell either. Bought the bike used and there is some tank rust that is I think causing some hesitation/surging issues. Replacing the tank and pump, air fiilter and plugs. The bike was definitely rideable but now is torn apart and the replacement tank and pump is most likely days away. The vendor has a shop called FASTESTTOYS. They better take care of me and ship the new one at least 2nd day air.

Good call on the 1000rr tank. Check some ebay auctions for that tank and this is exactly what it is. Bike is torn apart and I guess I will be waiting on this vendor to ship the correct tank. Thanks again MattKatz!

I bought it used on ebay from a bike dismantler. They had it advertised as a 600rr tank for a 2004-2005. I guess it could be a 1000rr tank. See below..

Ok. looking at the parts diagrams this should work, but I don't think it will unless this tank I got is not from a 2005. It was even advertised as fitting 2004 and 2005, but I don't think there is anyway the tank cover will fit over the 2005 tank. The tank itself is narrower by the rear subframe and wider at the front of the tank by 2 inches. Anybody have experience with this? Am I wrong somehow? Maybe the tank sits lower in the frame or something? Crap, this sucks. Sorry for the title confusion.

Yes. Had trouble reading the number on the tail of the bike. Not too familiar with all of the cbr9XXrr models that Honda used to have.

Looks like I got it wrong on the model. It was a cbr929rr.

I shook my head and declined the offer. We were doing about 65 at the time. Must be spring fever or something.

I hope this wasn't anyone here... I was on route 40 tonight sometime between 7:45 and 8:15 and after I passed a few cars a 2000 cbr 919 in white with red and black rolled up beside me. This guy indicated that he wanted to run me and I declined. Mind you he was wearing glasses and, sweatshirt and jeans. I was in my gear. Must be spring fever, or maybe I misinterpreted him.
