      Gv 650 Aquila St7 2015

      Hi, I’m Carlos, new to ride hyosung, buy this bike off of marketplace after searching around it’s the 2015 Aquila st7 model, I rode it home and when I arrive, and tried to go for ride again it won’t start, at first there’s a sound of the bike trying to start, it cranks, but now it wont making that same sound, the neutral light is getting dimmer, now is completely out, since the honks is getting quieter I assume it’s the battery, checked the wholesale for it couldn’t find the exact version, until my guy pointing out I’ve run out of fuel, the display shows a full tank though, I didn’t checked myself cause it is a big bike and when I tried to shake it, it is empty, I’m in Australia morningside looking for a mechanics or help anything I can get to get it fix,

      See if you can get a battery charger made for bikes (not cars!)  —> Charge the battery –>  Then try to start it.  And yes as long as there is at least 5 litres of unleaded petrol, the tank will have fuel.    The fuel pump does not like to start when tank is empty as it damages the fuel pump if it is dry. Very expensive part.

      After that , make sure to a pocket meter ====> Rev the bike to 5,000 rpm ==> voltage should be 13.5V-14.5V   and  idle  voltage should also be 13.5 to 14.5v

      If it is lower than 13.5v = charging system issues.

      If it is higher than 14.5v = charging system issues. I would NOT ride it until it is fixed

      Charging system =  Regulator (common) that is why we sell Japan upgrades on this shop ,  and Stator Unit   (if OEM regulator damaged it) and sometimes battery is too old and needs replacing with a new battery.

      Bike switched off ?  NO KEYS? ==> Battery should be 12.8v-13.1v charged.

      you mind suggesting the product for the charger, also how much is the fuel pump, I can blow at least 1k into this bike maybe more next week when I get paid, what should I expect the damages are and how they will cost me, thank you very much sir

      E5 is recommended ( 95% unleaded petrol and 5% ethanol max)

      E10 isn’t good, so try to avoid it if you can.
