Over the summer I put on a slip-on and fitler, and put in a 180 main, and moved the clip down to the bottom. Winter time rolled around and it started like crap! Changed the pilot finally to a 50, and played with the mixture screw. Fires first kick every time now even at like 10 below zero!

so yr poilt is 50 and how many turns is yr fuel mixtures screw?

the cold air in winter time condenses the air more creating a need to lean out the bike. what i did was put my hrc stlye lid back on my box and my occasional stalling issue is fixed ;)

Is yor airbox lid on or off? with thelid off--Your jetting should be a 50pilot, 2.5-3 turns out on the mix. screw, Needle in the 3rd from top, and a 170-175 main. What main do you have in now?
