Like a couple other posts stated, I prefer the method of getting the kick pedal up to the top of the stroke, and then "kicking it like I mean it". Of course, since I weigh about 130 pounds....
I have to jump a bit by kicking up off the ground or off the footpeg with my left foot, and then pretty much jump on the kickstarter. Works for me in 1 kick when its warm, I recently fired it up after 4-5 months of sitting and it took no more than 3 kicks.
Definately recommend wearing boots. I had my converse all stars on the other day and 1 time was all it took for me to decide to go change footwear.
Still, not as bad to start as my old RM465. That thing would actually kick you back if you weren't careful. Turned the whole side of my calf an ugly bluish purple and gave me a gimp for the next couple days.
