Had a serious problem couple of days back...
Without warning, in the middle of a ride, the engine simply cut-out. Since then, it does start but only works for about 10sec and cuts-out again (in fact the longer bike is left alone the longer it will work, but never for more than say 20sec). To me, it looks like fuel starvation which then points to a FPC failure. However, the FPC itself looks clean and rust-free (as I understand rust and dirt on its fins are prime cause of failure). Moreover, on ignition normal buzz sound of pump priming is heard and the bike electronics reports no failure. I don't want to take the bike for a service until I've got at least a vague idea what might be the problem.
At the moment I'm considering three possibilities:
1) Pump/FPC failure - what is the definitive way to prove/disprove this? How to pin-point the problem as either pump or FPC?
2) Spark plugs - will replace them all, but don't think they are the culprits as the failure was sudden and bike did not show any signs of deteriorating performance beforehand
3) Some sort of electronics failure - have no way to test this on my own but display and warning lights all look normal.
I would appreciate any new ideas and/or comments...
