I don't know the best way probably, but I usually kick it through about 10 times with the gas and choke on, with no throttle. I don't kick real hard until I'm sure it has gas flowing. Also, as with all kick-starting, try to push the kicker around to a compression stroke, then wind it up for a hard kick. If she won't go after a few solid attempts, I may crack the throttle during a kick or two. I always turn the choke off as soon as the bike's idle has a drastic change in its sound and RPM's. Every bike has a "personality" to it. Some bikes start better, if you lean them over until you see gas coming out of the over-flows. The 500 hundred can be a beast, to kick, and can wear-out a lighter rider, so try having a buddy hold the front tire and bars, so you can really get your weight into it.
