Quote from: greenman on 31 March 2017, 01:13:40 amI have to use full choke when engine is cold all year round, unless it's a really hot day, it always sputters in to life then once it smooths out and the revs rise (about 20 seconds) I can turn the choke off and runs sweet as after that.How clean are your carbs? Just a thought.Not sure about the carbs. I've only had the bike a month and never had them off. If I get the problem again I might start digging further, but whilst it's running ok I think I'll leave everything attached

So that's how i parked the bike in the photo this morning, up on the centre stand instead of the sidestand.Put the key in, hit the start button with no choke.......and it started straight off, no problem at all.I'm still thinking fuel related so what would cause it to not start being on the sidestand?Sidestand switch has been bypassed, so it's nothing to do with that, plus the sidestand was down as well anyway when it started up.
darrsi maybe it's time to break out that STP again.
Electrical if it stops that suddenly. Check all connections and wires around steering head for possible breaks and check connections on back of ignition switch
i would clean the carbs sounds like the floats are sticking and when you rock it , it lets some petrol through can you hear the pump prime the carbs when you switch it on ?

Parking it an angle on the side stand would be putting a small bit of sideways pressure on the float and float valves and making them stick worse whereas if the bike's parked upright then there's no sideways pressure on them they're less likely to stick. It's a long shot but I can't think of any other reason rocking it would make it start.
Could be the ignition switch, try bypassing it
Recheck your side stand bypass,clutch switch & wiring connectors to the starter cut off relay under the seat.Does the bike start as normal when left for a short length of time.

May be it's work shy.
Thread is a little old now - but often found on my fazer the battery was a little weak so turning the headlight off would often get it to start. If that fails don't sit they cranking it and flooding it - bump start it if you can.
Does anyone know what would happen with an intermittent TPS?I have had similar issues on cars and it has been either Cam or Crank sensors!!
