Hi, Info40176 and the usual suspects are:
1. Fouled spark plugs.
2. Severely discharged or a damaged battery 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.
3. Check battery 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.
4. Loose connection at ignition coil or plug between ignition sensor and module.
5. Spark plug cables in bad condition, shorting/leaking, spark plug cable connections loose check for spark leakage in the dark.
6. A faulty ignition coil or electronic control module.
7. Faulty pulse coil.
8. Faulty CKP, CMP, or BAS sensor.
9. Faulty ignition switch.
10. Faulty run/off switch
11. Tilt sensor needs a reset.
12. Security alarm failing to disarm needs reset

Hi, Anonymous 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 the 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 has 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 the 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.

Arriving at a fair price for any secondhand vehicle is very difficult and many variables should be considered though in the final analysis anything is only worth what the market will pay - if the seller asks too much the buyer will walk away.
There are many publications providing guide prices for all manner of vehicles - but these are only a guide and some models tend to command higher prices because of a good reputation while other models with a reputation for trouble or high running costs can fall far below.
No vehicle should be bought without a thorough inspection and price adjustments made for faults found and any pending work, taking due consideration of fair wear and tear.
A service history is important but will affect the price only if it can be fully verified by the presence of official invoices and a vehicle should only reach the guide price if the literature pack, the full complement of keys, tools, accessories, etc. is present. The replacement cost of some of the modern keys can be eye-watering so it is important to think ahead.
The presence of local dealer expertise and a spares service is worth a little extra and the absence of a local dealer drives the price down a little.
Firstly, I don't know whether the vehicle has an immobiliser or other type of anti-theft or security system but it would be an unusual modern vehicle if it doesn't and if so it might be the cause of the non-starting.
I am not familiar with the model but I expect it has many similarities with most modern vehicles where there is an engine management computer that drives the ignition coil and fuel injection system after processing information from a number of sensors. Replacing components without testing can be expensive and fruitless and unfortunately that needs a measure of experience and some specialised equipment.
You've got a Ignition System Issue which narrows things down quite a bit. It's either the ignition switch that your key goes into, or an on/off(run/stop) switch, or it's a relay for the ignition systems(or starter relay), if it's none of those then it's the starter solenoid that you've been jumping with the screwdriver, it sounds like the starter is working as it should since it turns over- the reason it turns over but won't actually run is because the ignition system won't work unless the key is inserted and in the run position, or if there's any other on/off switch that controls your engine it could be there. I'm not familiar with this exact bike but this is a common issue with all motorized machines! You can bypass all of this but that requires running some wires and a couple of switches plus a relay or two- that's an option but don't do that as your issue is nothing major and would be easier to fix than to go through the trouble of re-wiring it all. Just start troubleshooting and eliminate one part at a time, check relays, fuses, and electrical connections first, then the individual components I listed above and check to make sure they have power coming in and out when/where they're supposed to. If your bike turns over but won't run and the key is on, and you have a functional Ignition system then you need to verify you have ignition by checking your coil's output. EASIEST way to do so is pull a spark plug and connect it to the spark plug wire as you normally would, then hold the spark plug against the engine to ground it and turn it over- you'll see if you have any spark jumping aroundbetween the spark plug's electrode and the base of the plug itself. Either way, you'll get this figured out now that you know where to start and what to check!
Check all wiring connections and especially those on the battery, starter, and starter solenoid(if seperare from battery). It sounds like something is just making a bad connection since it won't even turn over- I bet your problem is in this area, good Luck and if I've been helpful please click the green button to let me know, Habe A Great Day!
Can be a loose / bad connection somewhere in the high current starter circuit, or a flat battery.
Did it start ok a few times when you put in the new battery?
Yes >> not charging the battery (or not charged when fitted).
No >> Bad connection between battery and frame or between battery and main ignition key power connection point (usually to a fuse).
The cause of solenoid clicking is the voltage dropping dramatically when the starter current begins to flow, usually a flat battery or a loose or dirty connection in the starter current circuit (will generate heat when clicking which can help you find it).
