Re: help to start my honda f4i
You poor soul... NGK IMR9C-9H is iridium, so you have a mix and match of iridium plugs brands, that should not matter. The photo below is of an IMR9C-9H iridium motorcycle plug.

Why don't you go check the fuel pressure regulator?
Remove your air box and turn the key on but do not start it. If fuel is going into the cylinder than your FPR is shot. If you remove the vacuum line from the diaphragm and there is fuel in the vacuum line then the FPR is shot. Very simple to check.
You need to use Google.

These stories from google sound familiar to you? They also suggest FPR or injector issues. As far as the oil goes, that is a different problem and may be more severe than your flooding problem goes. Change your oil ASAP, you have gas in it for sure and it will tear up your motor and transmission in no time. Then you will have oil leaks, blown motor/transmission/ and a fuel problem. One engine problem compounds others and makes them worse, especially in motorcycles that have a wet clutch because it uses your engine oil for the transmission.
Now that I have shown photos and posted links to other sites and I am for sure that I have shown you something to check, weather you check it or not is up to you. I bet you don't do it though. You need to READ EVERYTHING and if you don't understand it READ IT AGAIN.

Re: help to start my honda f4i
Did you take the diaphragm out of the FPR and inspect it for damages? Do you have vacuum leaks anywhere? Do you have gas in your vacuum lines? Something isn't right with your fuel return and it is dumping into your cylinder instead of recirculating back to the tank.
What is your idle screw set at?

Re: help to start my honda f4i
Let me go into detail about the fuel pump on your bike...
The fuel pump will pump the same pressure constantly, independent of RPM. It regulates the fuel pressure on the fuel rail by actuating a diaphragm in the FPR using engine vacuum that increases with engine RPM. If the FPR fails it will dump gas into cylinder 2 & 3 with full pressure flooding them rather than redirecting the gas back to the tank.
Is your fuel return hose blocked or pinched?
Does that make sense?

Re: help to start my honda f4i
i checked the FPR and it is ok, i jus needed some sparks plug because when i burn them they came back. the bike idle is 1500 rpm when it get hot and when i jus start it is at 1000 rpm.

Re: help to start my honda f4i
You have a serious problem somewhere else. Quit talking about the damned plugs. Your idle is seriously jacked too. It should idle higher at startup and slow down when it is warm. You're bike is way out of adjustment or something. First clue that your idle screw is set in the wrong position to compensate for other fuel related issues should be your jacked up idle.
I'm still betting you have problems on your fuel return line or other part of your fuel system because that should not flood, period, your bike is a fuel injected bike and the computer will not flood itself.
Your bike is jacked up and it is NOT JUST THE PLUGS, and I talked about more on the fuel rail than the FPR that you "checked". Have you sucked on the vacuum line to see if you tasted fuel in it? Do you know about vacuum leaks anywhere? Do you even know what a vacuum line is? Did you check the fuel return line? Holy **** I feel like a broken record repeating this **** so many times. READ WHAT I WROTE AND REREAD IT UNTIL YOU UNDERSTAND IT ALL AND HAVE DONE ALL THE SUGGESTIONS. If your FPR is really ok then I have given you other things to check beyond the FPR and all you are saying is the same **** back. If you post is exactly the same as the last post then don't even bother posting.

Re: help to start my honda f4i
Second thought, go **** with someone on the CBRforums, you're on the wrong web site for engine repair. We talk about stunting here.
Adios.
Unsubscribed and good luck.

Re: help to start my honda f4i
I'm an idiot that could fix your f4i in an evening, what does that make you? Seriously your answers have been posted here and all over the internet and you don't want to read and learn so I would rather be an idiot than ignorant.
Peace.
Can't help the ignorant.

Re: help to start my honda f4i
You're very welcome, hopefully you research all posted here and use the other forums posted or google to further your knowledge of the f4i engine and how it works. If you understand how it works you can make repairs a lot more efficiently.
Peace.
