It snowed last week. Its a bit below freezing today. I was prepping my bike for winter riding. I decided to fire it up because I've never it run it when its this cold out. It started perfectly on second kick. It idled 20 seconds and died.
I kicked it about 15 times. It seems like it wants to start, but it won't.
Pulled the spark plug. Its wet, its getting fuel. Injector must be working, fuel pump must be working, voltage regulator must be working, ECU must be working. The injector needs all of these to work in order to deliver fuel.
Checked for spark. There is none.
Put in a new spark plug for the fun of it. It won't start.
Checked the resistances on the ignition coil. Owners service manual, page 9-71. Primary side - 3.75 ohms. Right in the middle of the acceptable range. Secondary side - 20.4 Kohm, to either primary pin. Acceptable range is 10.71 to 14.49 K ohms. Failed ignition coil ? Service manual calls for replacement if its outside the acceptable range.
Could someone test their ignition coil to see what they get ?
Called the dealer. None in stock. There is 1 in Wisconsin. They are back ordered to Japan ? 3 to 4 weeks to get one ???? Is there some sort of problem with the ignition coils on these bikes ? FWIW, the FI YZ250F and YZ450F use the same coil. (Part number 33D-82310-00-00)
Last year my bike started on the first kick when hot. This riding season my bike went from needing 1 kick all the time when hot to sometimes needing 2, maybe 3.
On my last ride, a couple times it needed several kicks. Very unusual for my bike. This issue has been building for a while ?
I'm darn lucky this thing didn't stop out on the trail. Prior to this its been 100% reliable.
I'll update this thread as the situation unfolds.
