use syringe or turkey baster to remove what you can, if you can get a hose on it it should get 99% of it out, put the bike back together and start it, it may be rich for a bit but should clear up in few seconds, just don't shut it off till it warms a bit and make sure you do it outside cause it will be some heavy smoke screen, Had pretty much same thing happen to me and I started it IN the shop....
this is what I used in the past, Fork Oil level took
