Good day my 08 cbr1000rr became a big headache. When cold only 3 cylinders are working until 50 degree Celsius then the runs fine. I run Injector cleaner through the system and changed the plugs...checked the direct ignition coils...swopped the coils and problem stays on no.3 plug. Did found a bad wire on no.3 but soldering it back together....problem still there. Any ideas guys?
