I've had my motorcycle license since I was 17 years old, and I put off getting a bike because of other priorities (school, car etc.) I finally have a good ~$1000 of spending money and am interested in buying a motorcycle. I've done quite a bit of research and have found that 250cc-500cc is a good engine displacement to have on a first bike. So far I've found a plethora of mid-80's motorcycles within my price range. I'm looking at a Honda CB450 Nighthawk and a Kawasaki KZ440 at the moment and want some input on these and other bikes.
To make this thread more beneficial to others looking at getting a motorcycle it'd be good to hear some personal suggestions as well, like what your first bike was, and what you'd recommend to a beginner.
What should I look out for on mid-80's bikes as far as general wear is concerned? I've noticed that carburetors tend to need cleaning on 30 year old bikes, but what else should I watch out for.
