SOURCE: over filled oil yzf 450
Open the air box,clean it from extra oil,renew the air filter if you have to and without the air box-air filter (or opened) try to start the bike while sraying with a carb cleaner spray through the air box towards the carbs.Don't spray too much.Little bit each time and do not twist the gas grip.Choke it too if you want.It may help.Of course before all that set the oil level to normal.

I think that the WR version has electric start, but it may require that the engine cases be changed, pricey!!! Not to mention wiring, battery, and on.
