I don't know the bike but I doubt it is much different in principle than many others. The first possibility to consider is whether any immobiliser is functioning properly and is being properly disarmed before attempting to start. The owner's handbook would be a good place to begin...
Once you know the immobiliser is disarmed and power is flowing to the parts it is supposed to flow to, using the circuit diagram, the various supplies and grounds can be checked and using an oscilloscope check the output from the various sensors as applicable (crankshaft, camshaft).
Even though the bike has never been outside it might not have been immune from the effects of damp and condensation that can defeat many moisture barriers. It isn't unusual for electronic unit and sensor terminals to become dull, oxide coated and a barrier to current flow...
Easiest way would be to install a switch between the lights and the high beam switch. That way it would still come on only when high beams are on but you could turn them off. Alternately you could rewire them completely so they run only off of a switch, but then you would have to tun them on and off manually all the time. ---> expect to be pulled over for not dimming your lights when you encounter an oncoming police car and you forget they are on.
Hi, Greg the vast majority of service, parts fiche, and owners manuals on the internet are "FREE" to download and all service manuals contain wiring diagrams in the back pages. The rest usually charge a modest fee of $15 and there is a handful of obscure, rare, obsolete, and very old models that are no longer or never were available and some were never printed in English. The Indian and Philippine markets are usually in E-book format only, 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.

Hi, Don moisture, condensation, rain, or bike washing can make the bike run sluggish, not able to rev, and misfire. Older bikes, engine configuration, and exposed electrical components are at the front of the line for acting up. During the diagnostic procedure spray Electrical Contact Cleaner on corroded wire connectors/pins/sockets etc. and apply a liberal amount of "DIELECTRIC" grease to the mating harness/wire connectors. WD40 works great for eliminating suspect areas in your quest to find the real offending gremlin.
For additional insurance you can spray a High Temp Clear Coat on the most vulnerable areas it will work like Scotch Guard does on fabric. Fabricate a rubber or plastic splash guard to deflect water coming off the front wheel getting to the front cylinder spark plugs. The design should be adequate for its purpose with the least amount of airflow restriction to cool the cylinders. The usual suspects are:
1. Air filter soaked with water.
2. Water in the fuel system gas tank and carburetors.
3. Wet ignition coil packs.
4. Spark plug boots wore out or loose allowing water to enter.
5. Spark plug cables old and cracked check for spark leakage in the dark.
6. Spark plug wells filled up and drain holes clogged.
7. Water in a wire harness that has exposed open ends and have a sharp bend or crimp allowing the liquid to form its own pool of potential threats to chaffed wiring.
8. Sensitive fuel tuners and downloaded ECM remaps may get confused with the abnormal cylinder temperature difference in a V-4 engine configuration.
9. Fuel injected bikes need to have the electrical connectors removed and sprayed with contact cleaner then blown dry and checked for continuity with a test light or multimeter, then treated with Dielectric Grease.
If your bike will not run right or even start after going through the checklist, despair not, letting it sit for a couple of days in a warm environment is like an eviction notice for the Gremlins and then your bike will be back to its old self. You can speed up this process by using forced air to dry out electrical connections.
