2000 Honda 929RR Flooding, dumping fuel - 8/10/2008 10:26:25 PM

Hi everyone hope you guys can help
I just bought a 2000 929 RR that was parked for 18 months and the fuel was not drained when parked. The seller installed a new battery and without draining the old fuel added fresh fuel. The bike started and ran great for about 10 minutes, but it stalled and fuel started pouring out of the drain hole of the muffler and exhaust. I removed the oil fill cap and I can smell fuel in the oil too. Any ideas? I am going to remove the spark plugs to see if the cylinders are soaked with fuel. Any ideas what it could be doing this...maybe Injectors, sensors, ecu, etc.

Thanks in advance,
John

Hey there cudagee

Im not pro on fuel injected bikes but perhaps parking your bike for so long will have the same symptoms as my good old faithful carb powered beauty. Yeah your fuel should have been drained after standing for so long and your plugs should have been checked before the start. Hmm, smelling fuel in the oil, that doesn''t sound good.

Maybe your jets might have got clogged in the long stand. I hope the dealer didnt rev the engine too hard when he started it cuz your cylinders would have been bone dry from oil and revving it hard on the initial start would have been catastrophic for your rings if he revved it like a newbie. He should fix anything for being an idiot if anything was damaged under his watch.
Any other 929 addicts please correct me if I missed the mark.

Thanks Dukecbr,

I am going to drain the tank, drain the fuel from exhaust, inspect injectors, change the oil. I don''t think its the ECM unit considering the circumstances. Maybe one or two injectors are stuck open

Your fuel pressure regulator may have taken a crap, just something else to check.

Thanks Tacoma25, I''ll check it in the morning. All the cylinders are full of fuel all the way up to the throttle plate and the the exhaust pipe

Shit man, I was wondering how it got through all the way to the exhaust, you lucky it didnt ignite!!

Your sparks could have probably been buggered and that could have caused a shitty spark, not enough to ignite all the fuel. Eventually when it got soiled it wouldnt have sparked anymore, and then while your bike was sitting the fuel could have continued to run into the cylinders. I know carb machines have floats in them to cut off the fuel, what do injection machines have? Maybe check out that as well? Fuel pump?

Hope the info points you in the right direction...

It might be the ECM unit or fuel pressure regulator
I found a thread on the forum with the exact problem in March but there is no fix submitted

Does anyone know how to check the fuel pressure regulator?

Just had the same problem on my 929. Easiest way to check is to pull the vacume tube from the pressure regulator and see if fuel drips from where the vacume line connects to the pressure regulator. Usually you do this while the bike is running but can also test by turning the bike over. If so it''s gettting into the cylinders through the vacume tube. When these bikes sit for a while the rubber diaphram inside the pressure regulator dries out and cracks causing the leak. The only other way fuel would get to the combustion chamber is a stuck open injector but the pressure regulator is the easiest thing to check first. Don''t run the bike until you resolve the issue because fuel leaking this bad into the combustion chamber can hydrolock the engine and cause serious damage. Hope this helps.

Oh make sure there is fuel in the tank when doing this test and the fuel lines are connected to the fuel rail and pressure regulator otherwise this test won''t show accurate results. When I did the test all I had to do was turn the key to on because when the fuel pump primed it was enough to start leaking.

Hi Jeff, yes I checked this morning and yes there is fuel coming out of the vacuum side of the regulator
I ordered the regulator and I''ll be installing it in the morning. I will post it once I get it runing
Thank you so much

Update:
Yes it was the fuel pressure regulator. I drained 2 gallons of fuel from the crankcase about one gallon from the exhaust and the cylinders were full of gas also.The vacuum hose on the pressure regulator was full of gas so it was sucking into the motor. Replaced the pressure regulator, spark plugs, drained fuel from engine, exhaust, intake, Changed motor oil and filter with one click of the starter the 929 fired up. I took it for a test ride for few miles and changed the motor oil again with fresh oil. They should have some kind of fuel cut off so this doesn''t happened, I think one little spark this would have exploded.

I like to thank everyone for the help,

John
