A return to ridding

My apologize if this is the wrong section but please bare with me. Let me start out by saying that i am new to the sport and in the learning stages. about 8 months ago i bought an 05 crf250r and it was great didnt have a ton of time but still got it out weekends and what not. unfortunatly 2 months later i was in a motor vehicle accident that damaged the legements in my shoulder. and not really being able to do anything else with it the bike just sat on its stand gas drained and thats how it was. Getting to my question though i was wondering what to look out for as i start it up and get it out again after six months of sitting which im sure was a mistake but anyways if you guys could help me out it would be much apreciated.

yah i was checking it out a bit today and the oil doesnt seem right could condensation get into the oil its been in a garage with the butt plug in. i guess the best way to find out if its feelin ok is to fire it up though.
