    In downhills i run out of gas but i have about 3 lts gas on my tank. Is the fuel pump in the correct position on this model?

    Take the pump assy out and check the pump is securely located.

    Is the pump in the lowest place of the tank? I think that in dawnhills all the gas goes to thr front of the tank and thats why it runs out of fuel. Is it possible?

    Have to be a bloody steep and long hill.
    If the pump is correctly positioned & secure and the hoses inside the tank are ok then I'm at a bit of a loss.
    How old is the fuel filter? Maybe try a new one.
    Test the pumps performance both pressure and flow.
    Does your bike have a tilt sensor that stops the engine in case of a fall?

    I was thinking electrical. Does it idle okay? Possibly a problem with the filter or regulator that's exacerbated by the tilt.

    start the bike up, let idle a bit, and then pick up the rear wheel.

    it's a weird problem.

    also, characterize the problem for us... as soon as you head down, the motor stops or does it take a 5 min descent? how steep are we talking here? rough trails or smooth road? does it sputter? is restarting an issue? etc.

    In rough dawnhill trails if my tank is full with gas idont have any problem. In the same trail if im not full i have only 2-3 lt on the tank i run outt of gas. When the trail is over and find a streight road it starts up and runs fine!

    The fuel pump is at the lowest part of the tank but at the rear of the tank.

    Can the fuel pump drag gas from the front of the tank in dawnhills with some mods?

    Before you start modifying things I'd suggest something else is not quite right.
    I don't know about your particular model but my RS500 (which is effectively a 2010 TE510) has a rubber shroud or cover inside the tank around the fuel pump. I suspect it's to hold a supply of fuel at the pump when the fuel level is low and sloshing around the tank.....does your bike have this?

    ...not with 2-3 liters in the tank, unless you're going down long 45° hills.

    BTW, are you accelerating downhill or coasting? I've been assuming coasting but who knows?

    something is wrong. Could be plumbing (internal hose, filter, regulator), electrical (loose connection), or mechanical (your pump isn't strapped down etc). I suppose there could be a plastic bag floating around in there too.... naw. but your problem is probably NOT the inability to draw gas from the front of the tank when going downhill- I'm guessing.

    give us some GOOD pictures. Lots of 'em.

    Also you should get 100km per tank; 150km on a good day.

    A poster here had a rich running 450 and he got 25mpg (about 10km/lt)

    The placement of the pump in the rear of the tank is not a bug, it's a feature and rather convenient when you run low on gas.
    While it will stall on downhills it will start back up and run on uphills. If you are running out of gas it is the uphills where you need engine power the most.
    Harder to push uphill!

    OTOH 3 ltrs of gas is too much for this to start happening. The stock tank only holds 6 ltrs of usable fuel and that is a half a tank.
    So some reason that pump is not picking up fuel properly.

    On streight path or uphills works fine. My problem is only on long dawnhills
