I'm something of a noob, but looking at buying a Hyosung GV 250 for the wife. It's being sold by a local, private seller.
Overall, the bike looks mechanically sound - one female owner, regularly serviced (the bike, that is) - but on closer inspection I found a lot of oil on the lower frame under the engine casing.
The other bike I'm looking at is much cleaner. Is this a sign of a possible leak or gasket failure or something.
I'll get a mechanic to give the bike which I'd like to buy a good going over, but I don't want to waste money on a mobile mechanic if there's something really obvious going on.
Thanks in advance.
