Good call on the V Star - I bought a 2000 a few months ago with only 16,000 kms on it - rides a dream. Changing the oil is a ballache I'm told (you have to remove the exhaust) but as I haven't had to do it yet I guess I'll find out the hard way. Or you can buy an oil relocation kit which negates the exhaust removal drama entirely.
Other than that not sure there are too many issues, seems most folk that ride these bikes have nothing but good things to say about them.
Easy, rider =)
