went to little sahara this weekend, rode all morning sunday in about 40-55 or so temp, ran good. As day got warmer, probably around 60-70, it began to miss in the mid rpm range while under Full throttle. I changed plugs that had been in there for a while, they were pretty dark. went back out, it still missed. ANy suggestions.
