919 won't start after maintenance

Hello, I'm new to WristTwisters.

I purchased a 2007 Honda 919 right after Thanksgiving. Love the bike. I've ridden it only a dozen times since, because of weather. I spent a recent Saturday performing routine maintenance, changing oil, oil filter, blowing out air filter, check plugs, etc. I also added some mods to it at that time. Added mirror extensions, handlebar risers, windshield and sliders. I also installed the leads to the battery to allow easy connection to a charger. Everything went fine and I was proud that I accomplished so much . . . until I tried to start it. It would turn over but never start. The F1 light blinked nine times. The manual said that this meant the IAT sensor was bad. I figured I must have clipped it when checking the air filter so I ordered a replacement.

I put the replacement in today. Got the exact same response. Engine turns over, but doesn't start. Same effect as if it had no gas. If I let it turn over long enough, the F1 light starts blinking nine times again. I no longer believe its lies.

I'm stumped. What simple thing could I have done that has created this problem? Short of sacrificing virgin armadillos on a BBQ alter to rid the bike of the evil spirits, what suggestions do any of you have to track down my problem?

I'd check plugs, coil connections, and ground points etc. If it started all this after maintenance it usually is your fault.

Welcome to the site! Check the leads and make sure you tighten them down firmly on the battery. Then go and check your ground points.

ya... the coil thats on the left side of the frame under the tank is for cylinders 1 and 4 (one being the left most "clutch side" cylinder) and the coil thats under the frame centered is for 2 and 3... doesnt matter which lead of the 2 go to which 2 cylinders (as they both fire at the same time) but it will be apparent as the lengths are all different.

Did you remove the fuel tank? If so, is the little brown plug connected back up?

For future reference what is the brown wire for?

Fuel pump?

Thanks -- Bobby

Do you mean the brown plug? the brown plug is for the fuel pump in the tank......if the plug is disconnected the bike will turn over but will not start.

Latest update:

After reading this forum and others about similar problems, I decided to retrace my steps to find what I broke. I assumed that I had done some damage to electronics. After some searching, I found the brown wire from the fuel pump frayed. I couldn't tell if it was something new or had been there before I bought the bike. So, I taped up the exposed section. Then I looked up the wires and noticed that farther up the shrink wrap was melted. Once I cut it off, I found that much of the wire was melted away. I replaced the wire and plugged it back in. Fingers crossed, I turned the key. It still wouldn't start. I thought I might have blown some fuses and put exploring off until the next day. Today I have gone through checking fuses. I have found no bad ones but am still looking for something else that the short could have blown. Of course, I'm hoping that I didn't blow the fuel pump. I'm not sure how to determine that. I am already way past the technical skills I needed to keep my old '72 XL250 running.

could always grab a multimeter and make sure the pump is getting 12v at the connector... if yes... the more than likely bad pump... if no... then somewhere else down the line is bad.

I just had similar problems with my share 919. I took the two outside plugs out and replaced them with two used ones I had kicking around. Fired right up.

That's what happened with mine I think. Too much idle time over the last year and a half. I only changed the outside two because they are easy. The old ones were very black.

You need one of those bendable u-joint socket extensions. Makes it easy.
