Hows your plugs look now? What size jets are currently in the carb? if your plugs look black and you have the factory jets in the carb I'd consider going down about 4 sizes right off the bat considering your elevation. Then recheck your plugs if still to rich step down 2 sizes smaller at a time until you get the plugs tan or grey.
