Hi, Daniel that all depends on the age and condition of the battery, personally I do not recommend it, before testing any electrical component in the Charging System it is "IMPERATIVE" that you have a fully charged battery of 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage, the battery is faulty and must be replaced. AGM type batteries fall into this scenario more so than lead-acid batteries. All voltage readings will be on the DC scale except for Stator Output which will be AC you will need a multi-meter to conduct the following tests. "WARNING" never plug or unplug any electrical connector in the charging system with the engine running !!!
1. Check battery terminals for damage or corrosion, check battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
2. Check the voltage drop at the battery when you hit the starter button, anything below 9.6 volts you might have a faulty battery.
3. Make sure your voltage regulator is properly grounded with a clean tight connection, then check voltage at the battery with the bike running between 2000-3600 RPM, depending on your system specs, your readings should be 14.3 to 14.7 volts. If you are not getting these numbers or the reading is 15 volts or higher replace the voltage regulator.
4. Faulty regulator diodes can allow excessive amounts of voltage going back to the battery causing it to overheat, boil its contents and swell the casing. The excessive voltage will also spike the charging system allowing light bulbs to surge brighter than normal until they fail along with the main circuit breaker.
5. Unplug the connector to the alternator and hook your multimeter leads to the alternator (pin/socket selection does not matter) set the multimeter to AC volts, at an idle the multimeter should read 16 to 20 volts AC. at 2,000 RPM 32 to 40 AC volts, 3,000 RPM 48 to 60 AC volts. If you are not getting these numbers, you may have a faulty alternator rotor.
6. Set the multimeter to OHM'S, connect one lead to the alternator (any pin/socket) and the other to the ground, the multimeter should read infinity. Connect both leads to the alternator multimeter should read 0.1 to 0.2 OHM'S. If you are not getting these numbers, you have a bad stator.
7. Check all wiring in the charging circuit for worn or chaffed spots and all wiring connectors in the circuit for corroded, broken, or loose pins/sockets, which is the # 1 offender.

Hi, JB before diagnosing your blown fuse issue, check the bottom of your seat, if its metal and comes in close proximity to the positive battery post you need to take the necessary steps to ensure there is no contact (electrical tape, thick rubber insulation, hammer a dent in the seat bottom, etc.) You are going to need a wiring diagram from your service manual, a test light, an ohmmeter and plenty of extra fuses.
If you turn on your ignition switch and immediately blow a fuse you have a hard/dead short and is usually easy to find. With a test light connected to the hot side of the blown fuse holder start stabbing the wire/s that leads away from the fuse holder and towards the ignition switch, you test light will illuminate validating the short. When the test light fails to illuminate you have passed the short and need to back up until the test light illuminates, then look in the immediate area for the short.
If you driving down the road for 30 minutes or 15 miles and blow a fuse you have soft/flying short and may take some time and patience to find.
If the main fuse/circuit breaker constantly blows/trips while riding you probably have a faulty battery terminal connection. Check battery terminals for damage or corrosion, check battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary. Any other fuses that constantly keep blowing while riding are usually caused by a loose or corroded ground wire in the circuit, which means you have to check, inspect, test each and everyone with an ohmmeter set on a low ohm scale 100 ohms or less . Simply touch one lead to the ground source and the other lead to the battery negative terminal, a reading of zero indicates a clean solid ground. Any reading or infinity indicates a poor ground and needs to be repaired. Poor or weak grounds require excessive additional amperage to complete the circuit which in turn blows the small amperage fuse.

Hi, Anonymous the vast majority of service, parts fiche, and owners manuals on the internet are "FREE" to download and all service manuals contain specs-fluid requirements and capacities and wiring diagrams in the back pages. Another "FREE" source is online libraries you can join for a one month "FREE" trial then cancel at the end of the month. The rest usually charge a modest fee from $15-$20 and there is a handful of obscure, rare, obsolete, and very old models that are no longer or never were available, for these rare occasions I shall look on eBay and find the cheapest one available. Most of the manuals will cover your exact make, model, and year otherwise one will be provided that comes as close as possible to your bike and will have most of the same info that an exact manual would have. If there is no $ sign after the manual link it is free to download view and print.

Hi, Anonymous derestrict is a negative term rider's use to express their wish to improve performance on their bike or scooter. Depending on the country and motor vehicles laws some bikes and scooters are designed to conform with said laws and their performance is slightly lower than other countries. All vehicles in the world are designed to perform at 75-80% of their maximum potential, this ensures the longevity of the engine. Derestricting or improving performance is always possible on any vehicle but the tradeoff of engine longevity numbers go down, how much depends on the number and type of performance upgrades. Your local dealership or reputable independent shop are best equipped to provide you with technical data and willingness to comply with your needs.

Hi, Anonymous before you start it in the morning, pull the spark plugs and sniff them. Do they smell like gasoline? Are they wet? If so, you may have fuel leaking past the needle and seat in the carburetor and flooding the cylinders.
Use a voltmeter on the battery an hour after you shut the bike off. It should be at least 12.6 volts. Check it again in the morning. It should still be 12.6 volts or more. If not, something could be drawing current when the key is off.
If it's a carbureted bike and the ambient temperature is warm, you may be over-using your choke/enrichner. Try cranking it with the choke turned off first and then try half-choke, and then full choke. If you start with too much choke it will flood. After it starts, shut the choke off after 15 - 30 seconds and then use the throttle to keep the bike running until it warms up. Over-using the choke will soot up your spark plugs.
A fresh set of properly gapped spark plugs can make a lot of difference in how easily a bike starts.
Engines need a richer fuel mixture when they're cold. An intake leak can also cause hard starting because it leans out the air/fuel mixture.
After you get the bike started, spray some WD-40 or carb cleaner around the carburetor intake manifold seals. If the RPMs change, you have an intake leak.
