Any info appreciated!! Friend brought his bike to us. 2009 1125r. He washed the bike rode it 5 miles home killed it. 10 minutes later started bike went to put it in gear bike killed and won't start unless spraying in fuel injection system. Checked oil before he rode was good, now the oil is dirty and overflowing out of dipstick tube without bike runnin. Any thoughts? | ||

Ok I'm a little confused. Did he "kill" the bike on purpose the first time? Was the oil dirty the first time it was checked? I find it hard to believe that fresh oil got completely fouled up in 5 miles. What do you mean spraying into the system? | ||

Better explanation needed but here is my guessing from given info. How did you wash it pressure washer. dip tank or just run into the Mississippi. Just guessing but sounds like you filled the crankcase with water somehow, if so running it could have caused some grave issues internally. | ||

Yes he killed the bike went inside for 10 minutes. Started bike back up put it in gear and it killed. Ok oil level seems to be ok. They were checking oil level with bike straight up still strapped in back of truck but oil was clean. He changed it when he got the bike a month ago. Now it's dirty and they say it smells burnt. Think he sprayed wd40 or ether to start bike. It starts spraying into fuel injection system but won't start without. Is throwing a code fuel pump system | ||

Sorry guys I'm giving info as I get it. Bike has only been in our yard 20 minutes. Bike has fire they bead blasting plugs now just cause | ||
| Blade67 |
Everything on the computer system seems to be working. He washed the back end and underneath because the cane farmers were cutting down his road and road was muddy. He made sure not to wet anything. Not his first bike just his first buelle | ||
| Blade67 |
Ok can we maybe just discuss the code it's throwing. Fuel pump system. I'm a harley girl. I've never even sat on a buell. Only helping my old man (30 + year wrench cars trucks and HARLEYS) and his friend. | ||

Did he short out the fuel pump fuse and blow it? | ||
| Blade67 |
Fuse isn't blown. Trying to locate fuel pump relay And we assuming the fuel pump is in the tank since there is an o-ring on the fuel pump? | ||
| Blade67 |
we have the buzz from the fuel pump, but still no starting | ||

Ok relieve the pressure from the fuel system by unplugging the connector for it under the seat. Turn over the bike a couple of times so it clears the system. Remove the rear injector and plug the hole into the head with a paper towel. Keep the injector plugged into the fuel rail if possible and turn the key (don't point it at anything you care about. If possible put it in a glass jar) and see if it sprays. If you cannot keep the fuel injector attached to the fuel rail (sorry its been a while since I have done this, I can't remember if its possible) then remove it entirely and check for pressure at the end of the rail. Use caution though because this will spray gas everywhere if it is functioning. Again, glass jars are your friend. The fuel system runs at about 60 psi when the injector is mounted. That pump is no joke so PLEASE be careful. I'm only stating this test because I am assuming you do not have the correct fuel pressure test kit for this bike. If the bike passes this test then its time to move on to ignition. There is a chance that when the bike was soaked the rear coil got wet and ruined it. If that is the case then you will not have spark on the rear cylinder. I'm sure your old man knows how to perform a spark test. Its no different on the Buell. Only big difference is that you won't be able to do it on the front cylinder very easily. After that, move on to the throttle bodies. Always, always, always remember the 3 components for bang: fuel, air, spark. Check those first every time. Figure out which isn't working and we can help from there.

The bike has a fuel pressure sensor. Just go into diagnostic mode to see fuel pressure | ||

Hey thanks guys. Yes we have spark on the rear cyl. No we haven't had time to rotate the motor to check the front cyl. I'll pass this info to my old man. He does have pressure testing equipment don't know if it's compatible with the buell. Thanks for all the info. | ||

Do a search on the forum to see exactly how, but the front plug and coil can be removed without engine rotation Yes I'm aware there is a fuel pressure sensor on the bike and diag mode will read it, but the sensor is mounted on the center of the rail in between the injectors. Just because the sensor has a reading does not mean both cylinders are getting fuel. It also does not tell you if there is water in the fuel. Short of removing the pump or attempting to siphon the fuel, pulling an injector is a good method to check for water, as well as determine the health of the rail and injector. Also just for giggles a TPS reset never hurt anyone. | ||

Like Poppin' said put the bike in diagnostic mode and check the fuel pressure. The symptoms that you describe are no fuel. the fuel pump is at the rear of the frame and "should" be covered. but a pressure washer would force water in to places a garden hose would not, the owners manual is specific about not pressure washing the bike ( wheel bearings ) low fuel pressure or no pressure should code, and be stored. special adapters are required for external pressure test for the fuel system, if you want to check the pump the tank must be drained, [ plug rear of the frame bottom, left side] the pump is a bear to get out because of how it installs, but on the surface it sounds like water has been forced in to the pump or wiring I can provide more information this evening if desired.... |
