Bike won't start after installing PCIII and Exhaust
First, thank you for any and all ideas. Second, I know next to nothing about mechanical and electrical problems with cars/motorcycles, so I probably should have done this project with someone that does to learn from them. I figured this would be easy enough to learn, and I'm hopeful that with the expertise on this board it will be a success in the end. With that caveat, here is the problem: This afternoon and evening I installed a K&N air filter, a PCIII and a pair of Yoshi carbon fiber cans to my 2006 919. Everything was going smoothly until the VERY end of the project. After everything was installed and before replacing the tail section I started up the bike to make sure everything was running, and the bike started up right away. It sounded way better than the stock cans, which was very exciting. Figuring the project was successfully complete I turned off the bike, plugged in the tail light on the tail section, and screwed in the six bolts that hold on the tail section. I then turned the key to fire up the bike for a test drive, but the bike wouldn't start. Total bummer. The headlight/brights, turn signals, brake light all work just fine. Even the gauge needles do their pre-ignition movement, but the bike won't start at all. The PCIII still does its warm up sequence when I turn the key. Notably the bike doesn't make the electronic/grinding noise (starter priming?) it normally makes when the needles are doing their warm up thing. I figured it was probably just a blown fuse, so I checked the fuse box and all of the 10's and 20's in the box were just fine. I even replaced the first 20 in the ignition spot with a new fuse to no avail. I took apart the tail section again and ran through all of the wiring and connections to make sure that nothing had come undone when I re-installed the tail section, and I'm just not sure what to make of this. Particularly since the only thing that changed from the bike starting up with no problems to not starting at all was plugging in the brake light from the tail section... Any ideas? There was a 30 fuse that was a bit hard to pull and by this time of the evening I had to give up on the project, so that could be it. The 30 is not in the regular fuse box and I'm not sure what it's for. It didn't look blown from the top, but it may still be a problem. Besides all of the electronics appearing to work when the key is turned the bike doesn't make any noise or even try to start up now. I tried unplugging the tail light and starting it that way as that was the only thing that changed between starting up without a problem and not starting at all, but still no noise and no startup.
Other notable things about the bike - I'm the third owner. One of the previous owners installed aftermarket Rizoma turn signals with aftermarket wiring for the signals (very clean wiring that doesn't appear too complex). I previously installed a quick connection to my battery for a trickle charger and re-installed it when I hooked the battery back up after installing the PCIII. All of this was stable between starting the bike and then plugging in the brake light and the bike not starting. I think these are the only electronic additions that could be contributing to the problem. I have attached a picture of the setup under the seat. I apologize that it is not of better quality and doesn't show more, but it's the only one I could find on my phone at present. The only other thing that comes to mind is a random connector on the right side of the bike near where the PCIII hooks into the native ECU that wasn't connected to anything when I was really scanning the electronics on the last look over, but I'm pretty sure that that was not connected to anything when I started the whole project as their is no other connector to which it would attach. In other words, pretty sure that's not the problem.
Well, thank you for reading a very long post. Any ideas are welcome, and I'm hoping to get this thing sorted tomorrow evening as my bride and I were looking to go for a Saturday morning ride out to breakfast! Thanks again and I look forward to hearing from you guys.
