New Gasser!

[Birdman]

Hello all, I just got my first GasGas bike, an 2001 EC300. My first thought was to trade it in for a four stroke bike. However, after riding this past week and seeing the way it handles at low rpms, and the power it has when I need it..... I think I'm a gasser for life. Wow what a machine. Here are a couple questions I have:

Where can I get an owners manual?
Where are these bikes made?
I have ordered some new gaskets where the exhaust mounts to the motor, (FMF Gnarly pipe) the reason is that it leaks a large amount of exhaust and allot of noise comes from that connection, also I am leaking a small amount of oil after it warms up at the same connection.... will the gaskets help my leaking problem?

Thanks, Birdman
