yo dude. turn key as normal 2nd gear, clutch in- if no one to push then run with bike. let out the clutch fast and twist the throttle a little your bike should then start. once the bike kicks in let off the throttle and pull the clutch. be carefull dude, dont let the bike run away with you. Also if it doesn't work as you let the clutch out put your weight on the tank to help with rear wheel traction. check out some vids on youtube too mate

Yep with no fuel pressure, due to the pump not running it doesn't build enough fuel pressure, most fuel injected systems, when there is insufficient fuel pressure inhibit the firing of the injectors to allow the fuel pressure to build, hence they won't always bump off. The other problem you can get with bigger bikes, is if they are fitted with a slipper clutch they also won't bump off unless it's a tight slipper.
