I brought my Monkey home in December and rode it a few times before the weather turned bad. On those rides, the bike struggled on our steep, hilly roads (I'm at 8000') and was sucking gas. Even though it's fuel injected, the shop manual has a section which describes how to adjust the ECU for high-altitude riding. The adjustment requires a special tool (a jumper), which I purchased, and a sequence of opening and closing the throttle with the ignition on. I made the adjustment a few weeks ago but didn't have a chance to ride the bike again until today. All I can say is wow, what a noticeable difference. Now the bike will pull the hills with a degree of authority. It really scoots along (up to about 50 mph). Huge difference!
