The bike might have to much oil in the bike so when you try to kickstart it, it sends oil to the piston and soaks the spark plug in oil. But when you push start it the spark plug is going alot so it catches, just kicking it doesnt give enough spark tho. my bike doesnt the same and then somtimes i have to take the spark plug out and clean it with a wire brush then usually its fine. Or you could have the wrong oil in the bike, i would read the maunal to find the perfered oil. hope this helps

Compression leakdown test should be done first to determine if it has a valve wear problem which is the most common cause of your problem. Oil in the airbox boot is most commonly caused by compression blowby. This would be a function of worn piston/ring/cylinder clearances. The leakdown test would point this out also.
