This morning was my first "winter" ride on my 1999 XR600. Normally, the bike is a one or two kick starter when cold and a one kick starter when hot. This morning (25 degrees, 5,500 feet) the bike would not start. With each kick it would make a blubbering noise like it was trying to fire but die. I ended up having to push-start it down a gravel road to get it to run. Once it warmed up it was a one half-ass kick starter (4,000 feet to 7,500 feet). Is there some cold weather trick to make it easier to start? I weigh 140lbs; kicking for 10 minutes wears me out fast. "O"
