Yea the swing arm is pretty lame looking, but I like seeing the rear tire mostly idk why ive always liked the look of street bike rear tires, I want to get a 180 tire but I know that effects the bike alot/chain hits it.
And what exactly does running rich or lean mean? This is my first 600 I traded a 250 (stock) for it a couple months ago and I think it allready runs lean/rich because I can really smell the gas.... if thats what it is..

 

nevermind actually

 

That's what it is. If you're doing the bare tire look, at least throw some pinstriping on the rim. Makes a world of difference:
