Hi, Anonymous you could have a faulty sending unit or gauge, there could be a problem with your wiring. On models with the fuel gauge posing as a left-hand fuel cap the gauge is a press fit do not try to unscrew it, simply ample force lift up in a rocking motion to remove gauge. Disconnect wires to the gauge and with a set of positive and negative jumpers from the battery connect the positive jumper and flash the negative, gauge should peg full, if not replace the gauge. With a test light check for power to the sending unit, then remove the sending unit and manually operate the float arm slowly with the correct wiring hooked up to the fuel gauge and sending unit and the ignition on, the gauge should respond accordingly if not replace the float arm assembly. If your fuel gauge registers the incorrect amount of fuel in the tank you can try bending the float arm the necessary amount for a more accurate reading.

Sounds like one of two things. The electrical system (ignition coil) is breaking down. The fuel system ventilation system is blocked.

what kind of care you have in mind, either general or just the engine maintenance. Let me know if I will be more.

Your 125 may have a blown head gasket, water is entering the cylinder stopping the spark from sparking (causing cut out) and exiting from the exhasut, the steam is from the compression.

I am not familiar with the Mojito's qwarks. Sometimes the charging systems are underpowered and can't keep the batteries charged on some scooters. Check with Aprilia to see if there is a recall or service bulletin on the bike. If the bike started and ran fine when it was new, and you have the factory sized battery in the bike, then the problem is not with the battery size. If the battery is more than 2 years old, replace it. It may show as good on a volt meter, but it may not have sufficient amps to crank the engine, or be able to hold the charge. The dealer should also check the charging system to make sure it is charging at least 12.8V at idle, and well over 13V (volts) when the engine is revved up. Most scooters charge at 13.5V-14.7V when revved up. It shouldn't exceed 15V. An Aprilia dealer should have the factory specifications for the charging system and can test this in just 5 minutes. If you are having a charging issue, then it is most likely your voltage regulator/rectifier or your stator. The stator is what produces the electricity when the engine is running, the regulator is what smooths the power out and sends it to your battery at the proper voltage. Regulators fail more frequently than stators and are cheaper to repair. Other possible problems are the starter relay or the starter itself may be worn out and drawing too much power. Again, if the bike started fine when it was new, and you have the factory sized battery, then don't change the battery size. You may only be treating the symptom and not the problem. And applying more power can simply cause more damage. If the problem is that you just have to run the starter for a long time before it starts, and you just run the battery down, then it may have nothing to do with your starting system at all. It may be a low compression issue, dirty carb/fuel injection problem, old spark plug, etc. Hope this helps. www.solanocycle.com

hi, i beleive you have spent alot of money on this scooter, and for not much more you could have bought another machine, it sounds to me like the problem is with the electrics, as you say your mechanic has instaled a switch to cut of the power from the battery when the bike is not in use, this should not be the case as when your key is turned off there should be no drain on the battery at all, so i would sugest instead of fitting a switch, find out the reason for the battery drain and correct the fault, if you have a drain on the battery this may be a contributary factor in the poor starting, normaly modern bikes like yours require no opening of the throttle while starting, the whooing sound you mention could be the starter throwing out,and not engaging, because of the batteries low state. recharging the battery as many times as this is not good for the battery i would sugest obtaining a new battery from another agent, put the battery on the bike yourself, when you conect the battery leads with the key turned off you should conect the red posotive wire first, when you conect the earth neg wire to the battery as you touch it on the terminal you should have no power drain at all, power drain would be identifyed by a spark when conecting the lead, the more powerful the spark the heavyer the drain, care must be taken while doing this as a battery can explode if no spark is evident then there is no power drain, if a power drain is found then you should disconect things 1 at a time until you find the sorce of the fault, dont spend any more money unles you know it will rectify the fault.

Hello. The interesting thing about these small motor cycles is that their charging system is not adequate to keep the battery fully charged. I recommend that you charge the battery fully and then start it. When the battery is totally dead, even a kick start will not start it. The charging process may also indicate that your battery needs to be replaced. If you are still using the original battery on a 2005 I would begin by having that battery tested at any auto parts store.

If you are experiencing grinding noises and a power loss, I would look more to the power train and related components. Transmission, wheel bearing, brakes hanging.

With the engine off, I would push the bike slowly to determine if you are able to detect a grinding noise and if there is any resistence when pushing it.
