Just picked up two new left over 2006 Crossfire 700's. In the process of studding these machines, I discovered that one of these sleds has a major heat exchanger mod and the other (apparently early build) did not. Since I am sure AC made the improvement based on experience with inadequate cooling on the early build models, I am wondering if any other Crossfire riders have approached AC about a very "cost friendly" update to the early build model to avoid the aggravation of an unnecessarily overheated sled?
