Had a quick search on the tinterweb and this is a common crf problem with varying answers, valve clearances seem to be high up there. Also it says make sure the stroke is at top dead centre with the kick (i know from experience this can make a difference) push the kick all the way down let it up and push it down gently till you get resistance thats top dead centre. Give the throttle a twist 3 or 4 times to prime it then try it without the choke prime it again and then use the choke and see if it will fire. Its worth a try before you spend any money.
