Hi my 650 has decided not to start.. it was idle for about 4 mths that I did not start it.. i have spark but cannot see/ smell fuel and as I am used to Breganze bikes I am not sure about all the smart bits on the bike. I have cleaned all the connectors to the sensors but Is there a good manual on the system?? any suggestions/

on a more helpful base: check starter relay, check fuses. If the fuel-pump does not work, bike won't start. sometimes it is "just" the fuel-pump (which is a PITA to replace, if you can get a replacement part...), but most of the time it is a fuse or a broken cable. Or the side-stand relay... but the fact you have a spark would speak against that I think.

A 4-stroke only needs compression, spark and fuel and you seem to have two of those.
If you have spark then I assume the motor is turning over and the various sensors and ecu are working.
See if you've got fuel pressure, if not it's probably a relay, dead pump, or output pipe fallen off pump inside tank. First up, see if you hear the 'whirr" of the pump when you turn on ignition. If not, check relay first, then investigate further. If dead, the fuel pump can be replaced by various alternatives, people in oz have used them from Toyota Camry (ie complete piece of shit family car) and have worked the same and drawn less power. Note rubber pipes inside tank need to be rated for submersed usage.

What's you battery like, they are very sensitive to right voltage, you will as Steve said hear the fuel pump prime when you switch it on, have you done the the stand switch switch bypass? It's most probably that
You also need air in the room... have a check

Engine spins like crazy, but won't start. Might if you push it fast enough... over a cliff!

Wow, a spinning engine! It'd need to be balanced well, is that what they mean by balancing the carbies????
