Hey guys this bike is proving very frustrating.
Out for a ride yesterday and running ok for 30 minutes,came to stop at lights and it started to run rough. Same for next few stops and then I decided for some reason to turn off the headlight and mysteriously it ticked over fine and no issue back home.
Any thoughts anyone,same problem?
Cheers

 

Check your battery - misfire on tickover with a drain on the electrics sounds like the battery is not providing enough power to the coils.

 

You might want to move this to the F4 forum. Although the mechanical principles are pretty much the same, the layout of electrics, etc might be different for the F4 and the F.
