are you sure you’ve got the switch in the right position?
below from a varadero forum…
Turn fully anti-clockwise for off and fully clockwise for reserve. Middle position is normal and gives you about 15 litres from a full tank - reserve gives you another 2 litres.The tap should be marked - Off, Fuel, Res - but might be difficult so see.
How often to you switch the reserve tap on? Could be a blockage or dodgy petrol tap, not uncommon.
Did you open the filler cap and look in to see if you had petrol? I assume you did that as you’re not an idiot.
The ‘reserve’ tank is just a petrol outlet at the bottom of the tank. Your main outlet is a bit higher up, when the petrol level falls below that the engine will cut out. You then switch to reserve and the engine draws the petrol through the bottom of the tank.
Silt and muck from the petrol will often sink to the bottom of the tank, it’s possible your reserve outlet has been blocked by this.
Just had a qwick look for pics of ya fuel tap, looks like its gravaty fed , not vacuum , so probably dont have a prime on the tap,
If the tap is blocked, in the reserve position ,theres a chance u have cloged ya jets too ?
while the tank is empty , might be best to take the tap off , just to check, and clean the tap filter tube, make sure its clear in both normal and reserve positions .
( edited to remove info about injection , as just found urs is carb ,lol )
my vara is carb and has a choke, no injectors (the vara’s from 07 had fuel injection and a fuel light)
and yes, i looked in the tank, couldnt see any fuel. i can normally hear it swishing about too.
the fuel switch has 3 settings. on-off-reserve
it was on when it conked out, i then switched it to reserve. i dont leave it on off though, ever…
i have filled it up again with fuel, so cannot check the pipes for now. but i did think it was a separate tank completely for reserve. that would be a better design! or stick a frigging fuel gauge in the beginning so i wont get stuck! ffs
On older/simpler bikes/scoots a manual reserve switch just
allows the last few pints of petrol to flow out. When set to
main the fuel flows from an input an inch or so above the
bottom of the tank, when switched to reserve it flows from
near enough the bottom of the tank.
If you’ve not managed to switch over to reserve when it
was still running you may have to crank it over for a while
after you have stopped and switched it to reserve.
And make sure you switch it back to main when you fill up
or next time you run out there will be nothing in reserve :w00t:
