I have an 08 WR450 with the stock AIS kit and its suggested jetting. [i'm in MI at about 1k feet of elevation.] The bike runs flawlessly on the trails, but if I'm on the street at a constant RPM it starts surging. Question 1 - What are the ramifications of riding a few hours of street duty this weekend without making any changes? I'm assumings its a lean condition? Will it be lean enough to damage the motor? Is there a bandaid fix (like opening the airbox door, that would help the sitaution temporarily until I can fix it properly.) Question 2 - What is the correct fix?
