I have had to replace my pump...
never thought of low fuel level as
a possable issue....
But the tank "22.5L Gillimoto" was down
to it's last few liters when it died... Prob
less than 20mm of fuel around the pump..
Bikes a 09 XTR with 40,000k on it..
Pump only is worth about $30NZ off E-Bay ========>

or $800NZ plus for a complete unit from Yamaha.. Is the only way Yamaha sell it....
