if the ignition is good then its the fuel. Carburator off!
1st seat and gas tank off.
2nd Battery and airbox off. (you will need a long shaft screw driver for the airbox because its in a tight place to get to)
3rd unplug all the cables and pipes to the carburator (becarefull of the oil pipe it may split if you use too much force.) i find it easier to loose it on the pump end.(remember which pipe goes to which pin on the pump.)
4th release the carb screws at the junction to the manifold.
And you are done. you can leave the gass tube in place. and remember to drain the bows before you start removing the caarburator so that gas dont go everywhere down you clothes.
