you should be good.. what elevation are you at right now? the most you will have to do is play with the fuel screw a bit.. also bring some cold weather gear.. its colder then a mo-fo right now..

Kidding, right?

Anyway, it depends on the altitude of the tracks you're going to. If they're much below 2500 feet, you might do well to bump the main and pilot each up a notch.

The 165 should be OK. The 48 might be a little big, but in this cooler weather, that could be OK, too.

Slinky, just messin' with you a little :busted:
