Mother-cocking CBF125.

[Beez]

After about an hour of sub 15mph car park riding (teaching the missus), decided to call it a day and head home. Get up to about 20 mph, bike cuts out, subsequent attempts to restart are in vain.

Nothing abonormal leading up to it (slight rattling sound which I think was the L plate), no drama or weird noise when it cut out. After letting it cool down for a good 30 mins still no joy.

So far all I've checked is the oil level and the spark plug cap, partly because I don't really know what I'm doing and partly because I'm sick of looking at the bloody thing.

Anyone got any ideas?

EDIT: Fixed, see last post.

Really stupid question, it has got fuel hasnt it?

Take the spark plug out, Rest it against something that is earthed,

Crank the engine over (with the plug still attached to the lead) and see if it sparks.

Classic fadge juice ran into the air intake, and carb, subsequent fuelling shagged.

Empty tank or bin the misses.

Does the orange (MIL) lamp on the dash flash at all if you have the ignition on and kick the sidestand down? Or did it flash when the engine cut out? You can count the number of long and short flashes and match it up with a fault code, which narrows things down as to where to look.

Valve clearances being out of spec is a known cause of this sort of thing on the CBF as well and they're fairly easy to check.

Yes it's the kickstand that needs to be down for it to display a 'current' fault code.

Bring back the CG. None of this fault code flashing fuel injected blocking electric pump failing nonsense, it would take something major to not get you home.

Right well this is interesting.

Got the fairing completely off (impact drivers ftw) disconnected the fuel line from the pump, realised I didnt have any spare hose to test the pump with as per the Haynes manual, so just connected the fuel up again. Decided to try and fire the bike up again for giggles and it started first time

Any possibility this could of been caused by an air bubble in the line or such like? I really can't see how disconnecting and reconnecting the fuel line sorted it.

Just to update this post incase anyone else has the issue:

Bike left me stranded again last week, with another call to the RAC.

After checking the fuel hose, fuel pump, sparks and HT leads the RAC guy reaches in and pulls a cable out.

Turns out the issue all along was the power/ecu cable that connects to the injector throttle body was loose, but becuase it was hidden by a big rubber boot, no one (even the garage) had noticed it.

Clicked the bugger back in and started first time, bike now runs fine. HTH someone.
