Electrical Problem with brakes/starter
I've had my Ninja for just over 6 weeks now, I put about 1000 miles on it.
The only mod I've done was installing a Yoshimura Fender Eliminator Kit, I had to splice two wires from the old license plate light to the new license plate light. I crimped these wires together with the hardware provided which were two red plastic butt connectors. I was out riding and I had to stop for gas. I pulled into a gas station, and shut off my bike as usual. After I filled up and was ready to go I sat down on my bike and pulled in the clutch and squeezed the front brake. Out of no where the bike started right up. I was shocked, and after looking at it further I was able to figure out that when I pressed either the front or rear brakes, they would activate the starter motor. Even while the bike was running, if I pressed either brake you could hear the starter motor ingauge. The gas station I was at was connected to a subdivision in an urban area, and I attempted to go back through the subdivision to get my motorcycle home without any brakes, via downshifting, as to not destroy the starter. As I pulled out I shifted through gears, and was cruising in 4th gear at about 20-25mph. I made a couple of attempts on the brakes to see if the problem was still occuring, and it wasn't. Through out the whole situation, it happened randomly and then stopped happening randomly, and I have not been able to recreate the problem since. Can anybody give me some advice or tell me what is going on? Very much appreciated. |

You think there is some kind of short in that right hand assembly where the front brake and the starter all come together?
Thanks! |

honestly unless someone is playing a dirty trick on you, that's really the only thing it could be. it wouldnt be hard to run a line from the brake light to the starter relay which would be a hilarious trick and i'm totally gonna get someone with that in the future. but i doubt you got so lucky that the brake light wire and the starter relay input got shorted.

That would be very funny, but I am certain that is not the case.
But, check this out. I took it for a spin today when I got home from work. I rode about 8 miles. No issues what so ever. When I got back home I took the assembly on the right hand grip apart, all looked okay, and I didn't see anything that looked out of the ordinary. (I am good with mechanics, mainly cars however I am not out of my comfort zone with bikes although they are new to me.) After the assembly on the right hand grip checked out, I took the plastic side covers off, followed by the rider seat, and the passenger seat. I inspected all visible wires, and even gave all the ones I could reach a little jiggle. Still nothing, so I decided to put it all back together, and wait to see if the problem would occur again another day. I started the bike up, and began to put it all back together. While putting it back together I had the front seat, and the side plastics back on, and then the radiator fan kicked on. I sat on the bike and squeezed the front brake, and pushed my body weight forward a couple of times, as if checking the front brakes. As I did that, it happened again! I would click the front brake, and it would cause the starter motor to go. I even shut the bike off with the kill switch, and then started it again by squeezing the front brake only. Now, back home with the comfort of my own space and all my tools, I took the front seat, and side plastics back off again. I began to look for sparks, frayed wires and any other obvious signs of a problem, and still I found nothing. I jiggle the wires again, and out of no where the problem stopped. I check all of the wires I jiggled and I still found no outward signs of anything. As I did before, I tried to recreate the problem, I jiggled all of the wires again, and squeezed the brakes while putting my weight forward and It wouldn't do it again. I put the bike all the way back together and took it for a ride about 3 miles, It never happened again. Road perfectly. I really don't know what is going on here. |

I noticed you never said anything about your battery or fuse box. How were your lights and horn? I assume the bike idled and rode just fine? If it's a brand new bike, take it back to the dealer ASAP>

My horn, blinkers, gauges, and everything else to my knowledge works just fine. The bike rides completely normal.
I bought the bike on April 20th 2012. |

I had something similar happen on a Bandit years ago. The main wiring harness moved a bit, and at full lock it got itself crunched a bit at the steering stops. I realized when I pulled the clutch lever in, the starter motor spun. Neat trick!

I believe the wire that I moved around that caused it to stop happening was the main.
Thanks for all the help fellas. If it happens again I'm going to take it straight to the dealer. |

Found the culprit. It was a pinched bundle of wires to te starter button. It was pinched between the handlebar riser and the triple tree. It came that way from the factory. I guess it just took 2600 miles to rear its head. And all I wanted was a tank of gas for my road trip tomorrow...
