It's simple, but not the most fun task! Just trace the wiring down and find the issue as there probably is one, it perhaps it's just a blown fuse so check there first! If no luck, but a 12V outlet online or at a local parts store and wire it up, it's just 2 wires, you've got this!

We know the battery and gears are ok so that leaves us with the control switch. With a 12 volt test light follow the voltage to the switch. Check to see if voltage is coming for the the switch to the motor.

Pull the starter and examine the starter drive and/or actuating so,enoid. The starter gear should easily move in and out. You can bench test the starter too. You may have to replace it.

Hi, Frustrated one, engine "BOG" is mainly caused by a rich air and lean fuel condition but it can also be caused by a lean air and rich fuel condition this situation rarely occurs and is only caused by the misinformed weekend warrior that owns a toolbox. If the bike has been sitting for months or years you will have to completely disassemble the carburetor and submerge the parts (except rubber parts) in "Carburetor Dip" It usually comes in a gallon bucket with a wire mesh basket that can be purchased at any automotive store. If it is not the above scenario then the following explanation will apply.
The more you open your throttle the more vacuum you are creating in your carburetor venturi and your intake manifold. When you are operating at higher RPM any unmetered air that leaks into your system can become more obvious.
Unmetered air is air that is getting into your system after the fuel has been delivered. If you have unmetered air getting into your system between the butterfly/slide of the carburetor and the cylinder head this will create a lean condition.
All of the rubber components of the fuel system like vacuum hoses and intake manifold that you mount the carburetor to are made of rubber. If none of these components have been changed they are more than likely highly degraded and probably cracked in places to allow unwanted-unmetered-contaminated air into the combustion chamber. Check all of your vacuum lines and vacuum plugs for carburetor synchronization. The vacuum plugs are in the head just after the rubber intake manifolds. The petcock has a vacuum line as well as part of the emission system.
1. Check the intake manifold for fissures.
2. Ensure the bands used to tighten the manifolds down on the intake are secure and have not bound up the manifold.
3. Make sure air box fittings are not warped and fit completely over the carburetor.
Your airbox is metering air and is the first step in a process of consuming air and fuel. The system requires the resistance of the air filter in order to get the proper vacuum to "SUCK" the fuel out of the float bowl and create the proper venturi effect.
Improper mounting and sealing of the airbox will create a small lean effect. This might seem like no big deal but you are inviting dust and debris in your engine that is doing slow damage by not having proper fitment. Fix it so you know it's not contributing to your issue. Pick the low-hanging fruit first.
Do not go and start adjusting anything at this point. It ran fine before. There is something wrong with the assembly or a component. Do not adjust your floats. Get it back to where it was. The moment you start tweaking everything is the moment you lose OEM settings which are a must-have for fine-tuning and maximum performance.
Fine-tuning your carburetor and multi carb syncing come at the very end following the proper procedure established by the Carburetor Gods.

Have you checked the fuses? The fuse box is located on the left side of the bike, behind the fairing at about knee height. Check each fuse. There is a label inside the cover as a guide. I think your bike has separate fuses for left and right sides.

Hi, Phillip, it should be noted that the reasons your check engine light or CEL stays on constantly or flashes and your bike will or will not start and may turnover or not, these conditions will vary from bike to bike depending on the year, make, and model and you should always refer to your owners/service manual for proper diagnostic procedures. It should also be noted that any type of prior work done to the bike or an abnormal event occurrence IE: adding accessories, electrical curiosity or adventures, laying the bike down or crashes, rainstorms or bike washings just before CEL light issues started can be significant hints or aids into tracking down the gremlin, also for 2003 and older models carry the appropriate jumper wire to access fault codes and reduce the risk of being stranded or towed also keep in mind that your CEL comes to life if anything, and I do mean anything isn't 100% with the ECM like parameter spikes. This means that you could be staring at a major repair, or your speedometer sensor is contaminated and needs to be cleaned.
And the usual suspects are:
1. Severely discharged or a damaged battery check the terminals for damage or corrosion, check the 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, you should have 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 batteries fail in this scenario more so than lead-acid batteries.
2. Faulty charging system.
3. Faulty system sensor some models have up to 40 sensors
4. Faulty safety switches: run/off, ignition, clutch lever, neutral, side stand, tip over, fuel, and or their connections.
5. The engine got wet where it didn't like to get wet.
6. Faulty ignition circuit spark plugs, coils, cables etc.
7. Broken wire or worn insulation exposing wire to a ground situation especially inside wire harness at tight bends around fairing brackets, under dash panels, under fuel tanks over cylinder heads etc. Many harnesses are open on the ends that will allow water to enter and accumulate at v-bends.
Dielectric grease and contact cleaner are your best friends for wire/cable/harness connectors, look for corroded, broken, or loose pins/sockets. Run speedometer diagnostics and check for generated fault codes.
