Just got a new 2012 KLR 650 a month ago. Not my first KLR. After riding in extreme temperatures, turning off bike and coming back to it inside of 20 min., it will eventually start after cranking for 30 seconds. Never had problem like this with previous KLR's. Dealership, told me to use 91 octane fuel instead of 87. I don't know about that, my owners manual says 87 octane is called for. Seems like some kind of a vapor/pressure lock due to extreme ambient temperatures. Next time I will open gas cap and relieve pressure and then start. Anyone with similar issues that may have a remedy.
