I'm hours away from making the FCR dream a reality. Want to verify settings and looking for tips on where to buy needed parts. I'm running a stock S with a full yosh and a 3x3. I usually ride at 3000-6000 ft (4000-5000 most times). Low humidity with winter riding temps in the 40s and Summer in the 80s. If I am not mistaken, I need to be running the EMP needle as opposed to the EMN? Also, most likely a 150 main? I would like to know the best spot/price to pick up the needle and jet. Looking to avoid dropping an addt'l $72+ on a jet kit if I don't have to. Holler back! Thanks!
