Hello and welcome PaulD
You are indeed a lucky boy. What condition is the bike in and how original is it? If you have any pictures please post them. Whereabouts are you from?
When these bikes are set up and running properly there is very little that goes wrong as long as you look after them. Keep on top of the servicing and she will serve you well. All the general consumables are still quite readily available. I have many spares both new and used if there is anything you need specific. Parts are also available from Zpower.
Enjoy the site
