F1 Light issue
« on: March 14, 2019, 08:14:43 PM »
"When accelerating above 100kph the F1 light comes on solid and doesn't flash a code.
 It will clear once the bike is switched off and on again.
This issue will occur every time I accelerate quickly to just above 100 but if I accelerate slowly to just above 100 sometimes it won't come on.

Does anyone have any idea what could be causing this? "

Knock sensor wiring maybe, or perhaps a blocked 5 way connector??

Is it 100kph or 120kph?. The ST1300 computer will monitor the knock sensor and flag an error (if detected) by lighting the F1 light if the engine revs are held over 4200rpm (120kph+) for more than a few seconds.
If the light has come on at any stage you will be able to read it out by following the appropriate procedure as shown in the workshop manual.
