This is one of the few things that I recommend you take to a shop - you need some very special tools and techniques to fix this problem. Sorry,

SOURCE: yz 250 wont kickstart
You obviously look after your machine and very sensible when laying up, however as you are probably aware 2 strokes rely heavily on compression, A. to produce excellent combustion and B. to draw fuel into the chamber. So when you try kick starting you can't get enough revolutions to draw the correct amount of fuel into the cylinder, where as you push start you constantly turn over the engine increasing compression slightly and bingo it fires.
Can you remember how when kick starting it before this problem the feel on resistance when kicking over? has it now become a lot easier? if so you possibly have worn or broken compression piston rings.
A compression test will reveal this, I hope this sorts your query?

it depends on where it is leaking,if its a rocker cover gasket it would be reasonably inexpensive but if its a head gasket it wont be,check the rocker cover hold down bolts,they have a cup washer and a rubber seal under them,yamaha use them on fj,fz,fzr,xj etc and they do start to leak after a while(the rubber starts to harden with the engine heat),they are about 30c each and are easy to replace
