New GasGas rider

[youngun450]

Just wanted to say hi to all and say what a helpful site this is. I just bought a 1998 gasgas ec250 at a price I just couldnt turn away from. Its a great first bike but i do have some questions about it though. Now I did search but was just wondering if some of you guys could answer my questions cause i do not have a manual for this bike?

What kind of oil do you put in the gearbox and how much does it hold?

Where is a good place to buy parts from, I need a new rear brake line/air filters/brake pads, I live in Florida if that matters too?

Any info would be much appreciatted, thank you.
