Question about 2005 Aprilia Mojito Custom 125
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
