does it have efi? if not try twisting the throttle wide open 5 times before kicking should start 1st or 2nd kick
try a new spark plug that worked for my 150R
years ago, PDR taught me the trick of leaning the bike waaay over to the left side to get the gas running out through the carb until you get a little puddle of gas on the ground. I'll then give the bike a 1/4 throttle (if any at all) and she fires right up...1st or 2nd kick.
I never had any luck kicking pigs violently with lots if force. The least amount force and the smoothest possible kick always seemed to fire up the worst of them! Now my 2 smoke on the other hand loves 1 violent forceful kick and turns over no problem.
