Ugh Danno ! I do not like your Jetting chart ! Looks nothing like
the many other's I have seen...for bikes in general according to that chart my explanation was Over simplified and missing the jet needle completely
....
throughout all my motorcycle dealings the rule has been leave the needle jet alone ...it's fine the way it is and it matches the throttle valve cutaway.... so you get a 14:1 air ratio.... do anything to it and you mess up that ratio badly
in mid range RPM....
where did you get that chart Danno ? is it Ninja 250 spacific ?
.... I think I'm being taken back to school here ! LOL
