I have a 2009 kx450f took it out for a ride about a month ago it ran fine the whole day got back washed it. Went to take it out to the track the next weekend and the bike wouldn't start. I started looking further into it and I pulled the spark plug and gave it a few kicks and noticed that there was no spark. So I changed the plug out with a new one and still no luck. Then I tested the coil it was fine. And my buddy has the same bike as me so I started switching out parts from his bike with mine.I changed the:
Tipover sensor
Gear position sensor
Cdi box
Spark plug coil
New stator
Fuel pump
And still no spark. Now I have no idea what else to do. If anyone can help me I would really appreciate it. Thank you

Question though : Why did you check the fuel pump if you had no spark?
The Shop
MX690 I was just in the garage today. I checked the stator and the restantaces are in spec at 1 ohm. When I kick start the bike with a battery hooked up instead of the capacitor, the fuel pump will turn on but still no spark. When I kick the bike over with the capacitor in the bike (bike is making its own voltage) the fuel pump will not turn on nor does it have spark. I am thinking the flywheel lost its magnetism not generating enough voltage and not making the crank sensor pick up and trigger firing.
For the record, the guy that brought this bike to me let it sit outside all last winter. The ecu, fuel pump, and temp sensor were all broken.
That's exactly what my bike was doing, if I hooked up an external power source my fuel pump would work perfect, pumped about 125-150ml in 3 kicks. Running under its own power I got nothing more than a few drips out of my fuel pump. It just doesn't produce enough power to supply every thing. If you know someone that you can borrow their fly wheel from just to try that would be the way to go. Its not a common problem but can happen. I had my bike to Two Suzuki dealers and neither of them found the problem. Hope you fix it.
