Does it happen when it's parked on the center stand?
darrsi,just thinking could it be a electrical fault,connection or broken wire somewhere near the front end linked to the starting circuit,ignition switch if it starts after pumping the forks making the loom move connecting & disconnecting,a mare to trace but worth a look me thinks.
Darrsi is the fuel pump giving the dah dah dah then stops before you try to start?

ben17484, You defo flooded it this morning if you kept cranking it on full choke,if it don't start with choke on with first push of starter turn choke off before attempting to start again. The battery has gathered enough energy by sitting all day to start but you will need to go on a long run to recharge or put it on a charger suitable for bike batteries.Glad you got it sorted.
I 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.
Gently wheeled the bike out of the garage this morning, gave it one small plunge on the forks with the front brake, then it started first time no problems, on the side stand.Couple of revs, no choke used at all, and it sat and purred no problem whatsoever? I've put the bike on the centre stand outside work this morning, so i'll wait and see what happens when I go home later.So annoying, because it's so unpredictable.
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 ?
