hey guys, i cant seem to find a set of valves for my gk73a I theorise they could be the problem with my first and second cylinder, and even if they're not, i should replace them anyway.

HALP!

i've tryed ebay, froogle, google, etc etc and came up with a full wallet :/

What is making you think that you need valves?

cylinders 1 and 2 on bike arent functioning correctly despite having a spark, fuel and air... i can have it as a guess to be either cam timing, gasket leak or damaged valves although I haven't ruled out the possibility of a cracked head, there's no oil leak when i start it up through the cylinder which would rule out scoring within the cylinders and / or damaged piston rings.

although if you have any ideas i'd appreciate it.

Have a leak down test to determine if there is a problem or if you cant/wont do that take the head of and have a look.It will cost you a head gasket/time but at least you`ll know.....
