High altitude jetting for 99 WR400
Posted August 27, 2004 - 08:58 AM
My 400 was re-jetted for sea level couple of years ago (don’t remember what the specs were).
I moved the bike to my summer home (altitude is around 7000ft). It back fires on deceleration, also there is a little bit gurgling from ¾ to full throttle.
I dropped the main jet from 175 to 165 – no change. Also dropped the needle clip to the 2nd groove from the top.
PS: I have the stock can with the Baja insert, air box lid removed, and uni filter, gray wire is cut.
What are your recommendations?
