Last weekend, at 4500ft and at about 50*F I took the 500 for a full throttle pull up a long hill. Quad was running real good so I thought I would pull the plug to take a look. Running a DJ 165.
To my surprise, the plug was white/grey or lean. Air density at 100ft elevation with air temperatures around 75*F is 0.074lbs/ft3. At 4500ft at 50*F the air density is 0.066lbs/ft3. Most of the Florida guys seem to be running DJ 170's, yet with a way lower air density, I can't believe a 165 is so lean.
Am I missing something? Any help would be appreciated.
What are the guys that ride 500's further north or at higher elevations and using HMF pipes and high flow air filters using for jetting.
