Is the mileage actually 185, or is that a typo?? Of course, you will be looking at tires, battery, all fluids, etc,, on top of anything else you find. I guess the black stuff could be a failed fork seal?? I that condition, and with there being NO danger of you getting stuck with the bike if you find a "deal breaker", I would think that your original offer of $3,000 was a fair price. Maybe bump it to $3,500. The Road Star is a nice bike, and the dependability is there from Yamaha. Sounds like the offer he made you couldn't make things much safer!!!
Safe Riding, and let's see some pics.
