40mm Marzocchi Fork Rebuild - As fitted to GasGas Trials bikes

Here is a brief and quickly put together video showing you how to rebuild the rebound fork on your GasGas.
This is because if you don't do it correctly, you will end up with no rebound and will end up with a pogo stick for front suspension !
I hope it helps someone out there.
- you need 5W fork oil as standard. And you are putting 80ml of fork oil inside the dampening cartridge
The Manuals for the bikes can be found on the gasgas website
which is here:
