take the tank off,pour the gas in the intake then remove the plugs,now turn the motor over by hand with the kicker.....about ten times
then flip the whole bike over with the pipes off also,now turn the motor over some more with the kicker (by hand) another ten time and let it sit for about 2hours.
after that flip over,put in old plugs,get it running then install new plugs.
IF YOU DONT WANT TO PULL THE WHOLE ENGINE BACK OFF.
