Hey out there, my 2011 cbr250, dies intermittently , at about 3rd gear or so , it'll seem as if its sluggish then , speedo would jump from 30 to 60 then to 90 then dies. Any Suggestions Out there...Thanks in advance.
Could be an ECU problem; ECU doesn't use speed in calculating timing curves to my knowledge, so I don't think a speed sensor problem would cause your bike to stall. But, could also be a bad ground leading to the ECU that is also in the speed sensor bundle. Check all wiring and connections first.
