Trying to get my 1125R running. But when I go to start it nothing happens they lights dim and there is a load clicking noise coming from the relay box. I seems like it's the start relay. I am thinking the relay went bad. Has anyone had this happen? And does anyone know where I can pick one up? I am going to try swapping the battery in the morning. | ||

Sounds like your battery is dead. The voltage should be 12.8 volts (?) for a full charge. Small battery, little reserve, and a big draw. The battery needs to be in good shape to start the bike. | ||

I'd definitely suspect the battery being low first | ||
| Zhen13 |
Checked the battery at full charge it is at 13.1v. Was really hoping it was just the battery. I am going to swap it out anyway and see. I found a source for the relay. For $7.00 am going to pick one up. | ||

Is that 13.7 off the charger? If so that can be a surface charge and will fall off within 4 hours. You should pull the battery off the charger and let it set for 3-4 hours then check it again. We'll check battery for customers for no charge if they bring them in to our parts counter, my be your local dealer will do the same for you. If you can get the battery check done that will take the battery out of the equation. | ||

I traced the clicking noise to the the starter solenoid itself. I am going to try a different battery before I pull anything apart. And then check the wiring to and from the solenoid and made sure everything is tight and right. If that doesn't work I guess I will replace the solenoid. | ||

check grounds to clean and tight | ||

Ok, replaced the battery. And she will turn over but not fire. So it was the battery. The reason I had it apart was the fuel pump. I replaced it with a new factory part. So should be ok. I checked the fuel pump fuse it was good. Am re charging the battery and then I am going to check codes. But the fuel light came on, so I am thinking either the pump is not running or because it was completely empty maybe the system needs to be primed ? Is there a way to do prime the fuel system. | ||
| Zhen13 |
It's throwing P0628 fuel pump system error and P0087 Fuel pressure system error. So it's looking like my new pump is no good. Which is a shame was new in the box factory part. Paid like $250 | ||
| Nuts4mc |
There are issues with some of the fuel pump connection.... See here:http://www.badweatherbikers.com/buell/messages/290 431/778879.html?1455331243 | ||

Update I have been reading this thread http://www.badweatherbikers.com/buell/messages/290 431/783380.html?1461548242 There reason I originally had to replace the pump was I did what he did (reverse the battery connections with the wrong battery) As I stated I replaced the pump. But afterwards the bike still would not start. I replaced the battery as everyone had suggested. It will turn over but not fire. When I came across the thread above and read it I decided to replace the fuel pressure sensor. When I pulled the sensor there was gas at the sensor. So I figure the new pump is working, but the fuel is still not getting to the engine. I am hoping it's the sensor(ordered a new one from Harley) or possibly the used fuel rail I bought on eBay. But I will try the sensor first and then the rail. (Message edited by Zhen13 on April 25, 2016) | ||

Have you checked the start,ignition and key switch relays? I have had similar issues that ended up being a defective relay. | ||
| Zhen13 |
@Will No I have not. And considering the mis wired battery. I could see them being effected. Is there a way to check them or should I just order new ones? | ||
| Zhen13 |
Does anyone have the part numbers for the starter, ignition, and key switch relays? Thanks | ||
| Willmrx |
I removed the auxiliary relay and swapped it out with the other relays. | ||
| Zhen13 |
She's alive!!!!! Not exactly sure which it was. But I replaced the fuel sensor as suggested in the thread I linked above. ( the original problem I had was the the bike bucking and sputtering as soon as you would give it throttle. I thought it was a clutch problem or the slave going bad so I replaced the slave with an Oberon. But now I am thinking the sensor may have been bad or going all a long. After that I mis wired the battery and have been fixing the problems from that since. Voltage regulator, fuel pump. But she would not start) I also took Willmrx advice and replaced the relays. Reset the codes and she fired right up so I am happy. Thanks everyone for the help and advice. | ||

The bike is running, but unfortunately my original problem with the bike was heaving surging when you try and accelerate persists. When the surging happens there is a clanking noise coming from the left side of the bike almost like something engaging and disengaging. I have replaced the clutch slave which was my original line of thinking was the clutch. But it seems to function properly. I also replaced the fuel pressure sensor. I am going to run sea foam thru the tank in case the injectors are partially clogged. Was also thinking maybe the ECM is going bad? Any input is greatly appreciated. | ||

Make sure your starter connections are tight. Check ALL grounds for clean and tight. | ||
| Zhen13 |
I checked the starter connections and the grounds everything is clean and tight. I have been racking my brain for potential solutions. I do remember the original owner telling me the bike had a pipe on it before. I am wondering if the pipe was removed and the tune left in place could that cause a surging? I checked the ecm it is not marked race use only. But if it had been reflashed would it be marked. Was thinking I could check the firmware version with ecmspy? | ||
| Two_seasons |
Yes, former pipe with tune will affect ECM w/o pipe there now. Could have some cells with too much fuel in them. ECMspy can get you back to stock tune, but first you need to know what stock tune was! Any chance you can get your 1125 up here and we could look at it Saturday, swap in my 1125 stock ECM? PM me and I'll pick the message up tomorrow at work,. Give me your phone# and I'll respond asap. | ||

I have had exactly the same problems with my CR in this thread http://www.badweatherbikers.com/buell/messages/290 431/783380.html?1461548242 I replaced the fuel sensor and it has been no change at all too. Mine has a barkers exhaust with EBR ECM. I swapped it with my old standard ECM and it didn't change at all. Hopefully this may help you out a bit but now I am really stumped what it could be?????? | ||
| Zhen13 |
@Two_seasons Thanks, but unfortunately I don't have a trailer and in the bikes current state it is impossible to ride any distance. But I do have the stock ecm from my 09 1125CR which I noticed in the parts catalog the part number for the 1125R and 1125CR share the same ecm. So I am going to try and see if it makes any difference. Again thanks for the offer was very kind of you. @Emufriedchicken I have read your thread that was how I got the idea of changing the fuel pressure sensor. Unfortunately it did not work for me either. My current line of thinking was the ecm, but seeing it did not help you have lost some confidence it that theory. But I will try it regardless. The only other thoughts I have are to try cleaning the injectors( start with sea foam if that doesn't help I will pull them and have them cleaned properly). I also had thought perhaps the sprag was going( have heard of problems with them on these bikes.) But every thread I read about that said they had starting issues with a lot of noise on startup(don't have those issues). I am going to also thoroughly check the harness for any signs of wear and possible shorts to ground( I had a somewhat similar problem with my 03 XB9R that turned out to be a wire under the seat shorting out.) The only other thing I can think of is an issue with the transmission itself or the shifter mechanism. Otherwise I am at a loss. Did you do a tps reset after you swapped the ecm? | ||
| Two_seasons |
Always do a TPS reset when changing/swapping out an ECM. We'll meet up some other time. | ||
| Emufriedchicken |
@Two_seasons yes I did a TPS reset when I swapped the ECM around and checked the percentages in diagnostic mode too. I still get the check engine light and the surging continues. I bet its a simple fix that I am overlooking somewhere!! | ||
| Zhen13 |
Ok swapped the Ecm, and it's still surging and running like shit on throttle. (Ecm swap actually seemed to make it was but not sure if that was psychological.) So I am going to run some sea foam thru the fuel and see if that helps. Was reading troubleshooting in the manual and came up with the possibility the ignition coils or coil are going bad was going to pull the plugs, or at least the rear to start and see what it looks like. | ||
| Zhen13 |
Checked the codes got a new one P1047 feedback fuel cylinder difference too great. Says could be caused by a mechanical concern and may cause O2 sensor codes to set (not sure exactly what that means?) But I assume if one the plugs is partially fouled or the coil is malfunctioning could cause? Suggested remedies check all connections on fuel injectors, O2 sensors and ecm. Dirty or clogged injectors or loose 02 sensor. Loose leaking or cracked intake and exhaust manifold. So I am going test the the coils see if they spark. Check the plugs condition. Run sea foam and check the O2 sensors. Any input on this issue is appreciated. | ||

old procedure on cleaning plugs: go here; http://www.badweatherbikers.com/buell/messages/290 431/590843.html?1283192220 | ||
| Zhen13 |
@Nuts4mc Thanks I tried the plug cleaning procedure. I started it after doing the procedure a couple of times as was suggested. There was some white smoke out the exhaust. But it is raining here so I am not able to test ride it. | ||
| Emufriedchicken |
@Zhen13 I have been liasing with a local Buell tech here and he got me to try disconnecting the fuel pressure sensor wiring and go for a test ride. Other than the Check engine light that was on which he told me would happen, the bike has transformed back to how it should be...no bucking or surging at all. I have let him know and am waiting his response to my findings | ||
| Zhen13 |
@Emufriedchicken Thanks for the info. I will give it a shot as soon as the rain lets up here. Please keep me updated. |
