I've recently bought a 98 yz400f. I bought the bike as a non runner with the carb in a bag. Apparently the diaphragm was worn but upon inspection it looked ok to me. I thoroughly cleaned the carb but still no matter how much i kick the bike the plug is as dry as dust. does anyone know any tricks in getting these beasts running as my leg can't take anymore.

Start by doing it right. The YZ400/426 will start reliably, but only if you do it their way:

why would you think that a bike sold as "NON RUNNING" would start after you did nothing but put a part on that was obviously off for a reasson

How is that helpful?

Ok, if the plug is dry as dust, then you have to look into where your fuel stops flowing....
Does fuel make it into the bowl? (remove drain plug on bottom of bowl to find out)
If not - check your petcock - it may be gummed shut

and yes - as Grey said - the proper starting procedure is definitely key here.
