I rejetted my bike for the lower temperatures, I just follow the chart in the KTM manual and it's pretty spot on. My buddy is a local pro, he follows the manual jetting except running the needle 1 clip leaner than recommended. After riding 48 miles in the woods last Sunday, here's what happened. The bike ran well, but after the bike was warmed up for an hour, the it began to idle a little high, which in turn affected my riding every time I pulled in the clutch to brake-slide a turn. I adjusted the idle down to a kitten's pur, but the lean sounding naanananaanana continued on a smaller level every time I pulled the clutch while riding at race speed. So I raised the needle to the recommended specs last night. Also I checked the plug, the tip was caramel colored and the rest was chocolate colored. Would you all agree that it was running a bit lean?? I think that's also why I crashed at the end of the day on a natural terrain jump!!!! Couldn't be MY fault!!!
