1 - I don't want to sound like a jerk, but is the fuel petcock on? I drained a battery and kicked myself into a frenzy one time before I realized the fuel petcock was off
2 - My WR 250F used to have a terrible time starting if it sat for a week or so. I found out if I tip it on it's side to get fresh fuel in there, it would fire immediately.
I agree with the ideas above about the plugs, and would suggest you check the float bowl for gum - If it sat long, it may need to be cleaned.

Ya fuel was on. He literally hasnt ridden the bike for a few months so I am guessing bad gas. I am gonna buy a new plug and drain the carb and tank tonight. Now with these 4 stroke carbs, whats the best way to drain them? Thanks.
Pull the fuel hose, drain the tank.
Put the fuel hose back, fill with fresh gas.
On the float bowl, open the 3mm drain screw (it's pretty obvious) and flush a couple of bowls worth of gas into a tin.
Sometimes, just draining the float bowl a bit with old gas refilling the carb will get the engine started.

After 2 years, I had to replace the battery on my WR250F. If the vehicle sits with the battery connected, the battery sulphates and then it's a goner.

Haha ya thats for sure. Another thing I am not sure this is like how it is on the wr's, but I am used to 2 stroke, but do you actually have to take the tank off to change the plug? doesnt seem like too much room in there, I dont have to do it, just was curious.
I take it off. Just a few bolts and a clip. Takes 5 mins. But tbqh, I don't think that I've ever just changed the spark plug.
