Welcome aboard !!

Thanks guys... Like i said earlier i am a noob to riding and owning a bike.. If any one ca steer me in the rt direction on what i should do .. its a 2005 GS500F , 11K miles , the person whom i bought it from says that it sat for about 1 year it did have gas in it .. when i start the bike and its fairly worm it drops from 2K rpm to about 1K rpm.. i changed spark plugs on it still does the same thing .. Also engine sounds kinda rough i guess its the engine but it looks like the chain kinda skips ?? please advice txs in advance
