Hello Everyone,
I am a long time Honda car guy who is getting divorced, therefore to ease my pain I am looking at buying my first motorcycle.
It is a project bike, that I am willing to spend a lot of time on. I was looking for something under 500 cc's so I don't kill myself.

So I was looking at this:
82 Nighthawk
30,000 kilometers on it
Needs a fuel tank, and a little cleaning
It hasn't run for 7 years, but I am not too worried about that (I have a lot of experience wrenching on cars)
The guys is asking $400 which I feel is quite reasonable.
Now for the questions:
1 - Fuel tank - what fuel tanks will fit on this bike (can I get a tank from any year of Nighthawk with a 450 in it?)
2 - What in particular should I look at when looking at the bike? Are there any "impossible to get" parts on this bike?
3 - Is this bike known as the CB450SC?
4 - Any other advice would be appreciated.
Thanks in advance.
