Hi i had a bad crash last year with my bike and after the crash the bike wont start...there is no spark at the coil,the injector wont pulverise but the fuel pump works i mesure the 2 ckp sensor and the resistance is 240.8ohm and the alternator does give 12V because i tried it with a 12V light bulb and it fires...I check the regulator and the numbers are the same... the condensator also after i check it with V and than put it on ohm it discharge slowli the kill switch is new what can i try?

"CRF450R tip over sensor"
This will show you the images of various ones that Honda has used. It can go bad or I have even seen them installed upside down.
Also do a search on the site for the same thing and you will find some post of this issue on the 2009-2013 Hondas.
Most EFI bike have one.

Plus repeat your search on the tip over sensor...Use the wording I had posted. Do a copy and paste and see what you find.

Maybe take a tiny screwdriver and push into the back of the connectors while they are plugged in, this will sometimes reset a pin that moves backwards when you plug in the connector.
Had one with continuity, but once plugged in the pin moved and I couldn't see it was not making contact.
Push, pull, wiggle wire harness while kicking, see if it sparks.
Stator,ECU,Wire harness control spark.
You have no pulse, nothing firing the ECU, so it won't send the signal to the coil or injector.
I don't know how a Stator/Pulser can break in a crash, but it sounds like you have a bad Pulser?
Is there a simple resistance check for the Pulser, should be two wires?
You could have cracked the magnet on the flywheel?
The mystery no sparkers are always the hardest to figure out.
If you do not think it's the harness get the puller and inspect the magnet and stator.
