What kind of riding do you normally do? Trails/Sand/etc...I went up there a couple weeks ago and wished I had one size fatter on the main. My shee was jetted perfect for trails here in Memphis (3-400ft above sea level, respectively) and when I took my first rip down the dunes I started running hot. Normally for me my average operating temp here is 150-160 or so and in the first 10 minutes there I was at 190-200.
I agree 100% with sredish about not changing anything until you get there and run it first...you may not have to change anything at all. BUT, it would be a good idea to take a size bigger and smaller on your mains, and if worse case scenario you don't have the jet size you need, there is a shop there at LS that sells them. Temperature outside is getting colder and will definitely have a role in how your jetting should be too...
