06 WR450F Starting issue

I was getting ready for a weekend ride and my bike would not start up. I cranked it until the battery almost died than tried to kick start it. It still did not start. I changed the spark plug, had plenty of gas and everything else seemed to be okay. I’ve only had this bike out 4 times prior to this ride. I charged the battery and tried to start it—won’t start. I stoked up the stove in the shop thinking it was to cold to start as the ambient temperature is between 20-30 degrees —won’t start. Than today I went home for lunch and went to the shop to try to get it started, and viola—it started. The outside temperature had risen to above freezing, around 40 degrees. My question is has any one had issues with their WR450 not starting in sub-freezing temperatures?

This is normally a sign of a small starter {choke} jet.

I use a 72 starter jet with a 48 pilot for the winter. It should start a lot easier right down to 30 degrees. below that temperature you may need to kick it and crack the throttle ever so slightly.:lol:

i dont even try the elect. when its that cold i kick it call it names and it fires then no problums all day.

I've been having major problems with the ethanol blended fuel here in Hawaii. Even after running the carb dry, if the bike sits for over two weeks, the starting gremlins show up.
