Just installed Boysens in My 01 RM250, it states on the instructions to use the 3rd groove on the needle, it looks like they are referencing an older carb style? Inotice there is a rachet style set up on mine ( not like the old days) :blah: Anyway any advise would be much appreciated before I put it back together.
