..My firend just got his ' 03 650..he now has about 75 miles on it..it Pop's/spits in the air clean box...we are at 1000 ft sea level....if he puts a little choke on, it comes out of it..but if you leave the choke on even a little, it then is too rich...can these carbs be adjusted richer, or do we (Mine will be here this week!!) need to put a jet kit in it...and who makes the best jet kit..Thanks in advance.....!!

 

75 miles on it??? Take it back to the dealer and let them deal with it!

 

Mine sometimes pop thru the carbs until it has warmed up a bit.
