Hello I live in Alaska and I need some help jetting my shee. It's about 0-10 degrees below Zero. It's very close to sea level. The machine has FMF pipes, boysen reeds, stock carbs, Aluminium air box with duel filters and coolhead with 22cc domes. I've checked the choke tube in between the carbes and it's good. Both the carbes are tuned exactaly the same. It bogs rite off the bat and sputters when I have it at high speeds. I have 300 mains and not sure what the pilots are and the clips are in the middle. 3rd clip. If you havent been racing on an ice track you should try it!! It's great fun!!
