No idle no start

[R1der851]

I recently did the valve adjustment at 20k this week. I wound up doing the job twice due to a noisy chain or tensioner. I had put everything back together the 1st time. On the 2nd time I left off the airbox to run the engine and listen for any ticking.
I initially had no codes P0000 after the 1st run. Now I have 0108, 0113, 0413, 0460, 1698 and 2111. Most of these relate to the sensors and hoses being disconnected with the airbox so I hope they will all go away. I did have bars on the fuel gauge now have nothing. Understand that can be due to the bike not moving. Battery has been in and out and left on a trickle charger.
This is my observation and concern. No airbox or sensors plugged in the bike will idle fine. Ran until the cooling fans kick on. Key on engine off the butterflies will not open all the way? Airbox on and everything connected bike will not start?
Any suggestions?

Thanks

Gotta ask...  Is the kill switch in the run position?

[R1der851]

Kill switch is working. Wiggled the wires on the handlebars and each wire going into each sensor on the airbox. Since the bike already demonstrated it can run with all those sensors unplugged, I'm confused that it won't run when they are plugged in. Even if they were to some how simultaneously all have broken? I'm definitely missing something.

As it says, the motorcycle starts without the need for the AirBox connectors to be plugged in, that is, the DTCs will appear that you can erase later.

If the connectors that go to the fuel tank are plugged in, you should start your motorcycle.

If you have that, it is correctly plugged in.

Check the starter solenoid relay that is located next to the battery, it is possible that some of the two cables that have faston type connectors have come out and will prevent the motorcycle from starting.

As in the engine will turn over but won't start or engine won't even turn over?

[R1der851]

Yes the engine spins over very strong. Just won't fire. I'm going to try unhooking all the sensors but leave the airbox on and see what happens.
Just think it is strange that I could start it without touching the throttle with no airbox.

Have you tried unhooking the battery, plugging everything back in, hooking the battery back up, and then starting the engine?

[R1der851]

OK, made a little progress. I unplugged each sensor in the airbox one at a time. Narrowed it down to the MAP sensor. I am having trouble getting the bike to "adapt" as I have to unplug the sensor or disconnect the rubber that goes to it.

Once the engine is running I can leave it to idle while I reconnect the MAP sensor. I let it idle for around 15 minutes. During that time the rpms would change up and down until it settled in to about 1000. There was a noticeable drop where I thought I lost a cyl. The timing chain still makes more noise than I like and when this rpm drop occurred the ticking of the chain stopped along with it. I let it idle quietly while the cooling fans kicked on and off. Any restart requires disconnecting the MAP sensor or a little twist of the throttle. Playing with the throttle won't get you a running bike that can be left to idle.

No new codes but nothing has dropped off either.

I'm tempted to go take the bike for a ride but am at the end of a 1/4mile gravel road that isn't entirely flat. Don't feel like pushing it if things don't work out.
