EC125 gastank tube, radiator cover, breath tube.
 

Hi, Ive got a Gasgas ec 125 2005. Is the gas tank tube important?
Also the carther breath tube for the engine, one end connects to the engine, where does the other end go?
Also, i only got 1 radiator cover, or is that normal for the ec125?

1) Yes. Allows the fuel tank to breathe and not let fuel splash back on you.
2) Just run it up alongside the right radiator, or under the tank. Doesn't connect to anything.
3) Should have 1 on each side.

Oh okey thanks. Where does the fuel tank tube hook up? Also is the radiator cover really important? Do I need to buy one

The tube coming off the fuel cap is stuck into the the triple clamp steering stem nut.
Radiator cover helps with cooling and some protection from trail debris.

My gastank tube is cut off. Does it matter or does it do the job?

If the hose is gone completely or short and the end is open and pointing up, water can get inside an cause you problems.

Yeah I can fix that somehow. As long as there is ont, cut off or not, its gonna do the trick rght?

The hose is just just common fuel hose or vacuum line so you can get it from any hardware or auto parts store.

Yes but like does it matter if mine is cut off? Yes it can collect rain and dirt but does it still do the job or does it not work at all?

Without the hose, the water and dirt will funnel right into the fuel tank.
If yours is cut off, you will need a new fuel cap.
