I'm riding the same elevation around Alamosa, CO (up to 13K) and running a 155 main with a 38 pilot, needle buried (forgot which needle) on my 300. My buds '11 ec300 has a 152 and a 42.
Funny, 2 years ago I drove all the way to Woodland Park to buy my gasser off a mechanic who has 2 automotive shops there (Vasholtz). He is a well decorated Pikes Peak racer (cars and bikes). He sold his gasser to me because he switched to Husky's because his son got a sponsorship by Husky. Drop by his shop, ask for Clint, super nice guy, he can give you some beta on local riding. Beautiful town, you will love it. Nearest gasser shop that I know of is Fritz Kadlec's Gunnison Motorsports. Super great resource, keeps a good amount of parts in stock. Welcome to Calarada
