put different injectors in it, ran rich but still the same
pulled the turbo off running just motor. in the process of tuning the bike to set up the spray. motor still has the turbo 9:1 pistons, really i changed nothing just removed the turbo. the a/f fuel is fine right up to 7000 then goes all over the place. it kinda acts like it is hitting the rev limiter, just not as pronounced. i disconnected both power commanders and tried just the ecu-same. valves not closing at that rpm?? pistons in backwards????? cams out of time?? ecu not advancing timing??? i am almost to the point of pulling the motor out and starting over. :icon_wall: :icon_doh:
