My 99 WR is jetted perfectly for the Idaho mountains 6K to 9K feet. Always starts with one kick and never had any starting problems......until this weekend. Went up hunting and the morning temp was around 25F or -5C. It took me forever to get my bike started first thing in the morning. Once started it ran pretty good, but not perfectly as stated above. Anybody else in the forum ever start their bike in extreme cold weather. What did you need to do?
