i have a hf 6.5, its about 35 degrees out here right now. i rode the bike a lot in 15-25 degree weather with no problems starting or any thing, but after riding in the snow it takes choke and gas rather than just choke to start. im wondering if this has any thing to do with over revving it in the snow, the gov is still in but it was hitting the gov pretty quick then hooking up and dropping rpms
