I dont post alot on here but I seem to be having an issue with cold starting, I live in the great yahoo state of North Dakota, the weather is in the 30s now. I have a 09 1125R, OHSB tune with hmf exhaust and K&N air filter, is has the Screamin Eagle HD Oil and for the life of me I cannot get the bitch to fire. sure it turns over and spits but just does not want to fire. i did put a heater next to it for awhile and after a long while i was finally able to get it to go but when i did boy did it idle rough for at least 5 minutes but then came back to normal. so does anyone have any suggestions on how to start this thing in the cold? what the rough idling was? any info would help  in this bloody state taking it to a dealership is out of the question because there is only 1 in this deserted wasteland | ||

Use lower viscosity oil while it's cold. 10w40 is fine up to 50-60 degrees. I currently run Mobil 1 15w50 full synthetic, even with the low temps it's starting fine. Make sure the battery has a full charge before trying to start it and yes, the space heater will help some. Rough idle, mine only lasts for about 2 minutes and that was at 17 degrees that particular day. I did a video of it since I missed riding, had to do something to have fun then. | ||

thanks for the tip D_adams. i had a feeling the oil had some part in it. | ||

Good luck. They're not happy in the cold. I've had mine nearly not start at 18F, a friend with the same bike had trouble below 20F, and even if it's in a garage and starts, it runs rather rough when sucking down really cold intake air. My personal feeling is that nobody bothered to check the fuel/starting map in the "extreme" cold. I suspect it's too rich when it's really cold - probably just extrapolating the normal starting map up in the cold and putting in too much fuel to light. It *should* start right up, but you could try cracking the throttle open a bit to help get some air in to mix with the fuel it seems to dump in on a cold start. And, yeah, the "PFUHT" out the exhaust seems to happen consistently on cold starts too. Further data points for my suspicion it's too rich in the cold. Or too lean, but it sure seems rich to me. Either way, if it's going to be below about 20F, I take a car, because I can't rely on the bike lighting up before the battery dies. If you work something out, I'm certainly interested to know. I'd also be interested in someone in a cold area playing with the ECU cold starting maps in (insert method here) to see if they could improve it - a modern, fuel injected engine should NOT have trouble starting down to well below 0F! | ||

i agree with you 100% in the fact that a fuel injected engine shouldnt have a problem starting in the cold but damn is it a bastard to start. you do have a good theory tho about it likes to run rich in the cold...however, i do not have data on ECU cold starting maps  | ||

This motor floods easier than any I have ever seen. Do NOT touch the throttle when starting. If the motor doesn't fire after 5-8 revolutions, stop, wait a few seconds and try again. Let the fuel rail pressurize and just push the yellow button, she'll start. I rode to work a few weeks ago when it was 4dF outside, my garage is about 20dF. I think she took 3 tries that morning, but started and ran fine. Zack | ||

+100 zac4mac .... only touch the yellow button! | ||

well i made a dumb mistake then lol, its flooded I was curious to see how the spark plugs looked and I am no mechanic but what does it mean when they are black on the top and have a strong smell of gasoline? in either case i ordered some new ones. how would i get the bike to "deflood"? | ||

Justin.........."I am no mechanic but what does it mean when they are black on the top and have a strong smell of gasoline? in either case i ordered some new ones." With that said did you go to all the trouble (considerable) to pull the plugs just to see how they look? Also, did you know there is a way to fire the plugs and clean them without pulling them. Just wondering, please clarify. Bob | ||

I have heard of this firing the plug on the 1125's to clean them can some one please tell the procedure to do this could come in handy some time | ||

Automatic: Starting the engine without running it up to operating temperature can foul the spark plugs. To execute a spark plug clean, the ECM rapidly fires the spark plug up to three times without enabling a start. The ECM records the number of starts without running up to operating temperature. After five starts without running up to operating temperature, the ECM will automatically execute a spark plug clean before starting the engine. Manual: If fouled plugs are suspected, a spark plug clean can be initiated manually. Repeat the following sequence three times: 1. Roll and hold the throttle wide open. 2. Turn the ignition to ON. 3. Wait three seconds. 4. Release the throttle grip. 5. Turn the ignition to OFF. | ||

well as we all should know by now the rear plug is easy to get to and the front one requires the rotating of the engine, i did not rotate the engine to get the front plug out thanks to RedBuell1203s method of removing it. I did use the spark plug cleaning procedure in the manual and when doing so i did get a pop from the exhaust. but still after many many attempts the bike refused to fire, it does crank over fine and not hard at all so i only assumed that something was wrong with the spark plugs and the fact i twisted the throttle a few times while starting and now its flooded. it doesnt make sense to me on how in january when i got the bike back from the dealer it started fine and now 2 months later its virtually impossible...the only thing i did to it in that period of time was putting on the OHSB tune thus increasing the AFV values. | ||

Justin, theres a hint in your last post. If thats all you did (your last line)I would look at that as being a negative to what you are experiencing. Good to see you are reading a lot of info here as to Redbuells spark plug post. Maybe start over with a stock setup and go from there. Good luck and don't let this small thing discourage you from our great 1125's. Bob |
