My Aprilia Mojito 125 doesen't star. Ive had it to repair shop several times, they says battery is to small for the bike. Can I have the battery moved from glove box to under the seat and increase the ...
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
yes battery was charged fully and didnt have a dramer stating until stator was reconed
yes battery ends up flat, i can eventualy smell the fuel, the problem is only when its cold,last night i noticed when indicators are being used the head light flickered
Was the new battery ever put on a charger? So many shops just fill with acid and hand them over without telling the customer to make sure you charge them the first time as filling it will only give you about a 50% charge and for some rectifiers that just isn't enough to ever get that battery fully charged. Take the battery out put it on a charger overnight, maybe just that easy!
