Engine cutting out

Hi, from Friday evening until Monday morning i somehow left the ignition switched on on my R reg 900 Trident. Does anyone know if this could damage something in the electrical system. It could of course be coincidental but now i have a problem with the engine instantly cutting out. after a while it will start again ,only to die again 1/2 a mile later. Fuel problems have been ruled out. many thanks

 

over looking the fuel system as you state thats ok
Is the Battery ok ? is it charging ok ?
If the battery is ok and is charging ok then I would try this -
Daft as this may read I would try disconnecting the battery leads overnight and reconnect it in the morning and see how things go.

 

get your battery on a full charge over night, then ride it and see what happens

 

Agree with the above - always start with the battery.

 

Thanks...Battery does appear to be ok . had it on charge for 24 hours using smart charger and is holding a charge. Bike starts crisply .

 

Thanks Tez, I will try this overnight .

 

may possibly be the crank position sensor failing. if it restarts after a few mins cooling down and then stops again it is a good bet. still think go simple stuff first tho. are you sure fuel system is def ok??,try running the bike on prime setting on fuel tap,vacuum may be blocked

 

Many thanks all.... Spritdave hit the nail on the head ...Crank position sensor it was. Appreciate all your suggestions .
