I have to be sorry to be a bearer of bad news but when you start a bike , with a “truck running” , it means you sent too much “amps” (not volts)
14V is good but its like sending 5 gorillas to lift the bike up instead of needing just one , so it gets crushed when squeezed out by all 5. In other words thje strength of the current was too much for the bike even though it started.
It would likely mean
- Fried up stator
- 100000% fried up regulator (as you said it was insanely hot) , its not normal at all.
- If its an EFi bike, you possibly may end up having to replace defective sensors all over the bike one by one that use energy, such as your coils , ISCV, Lambda Probe o2, etc.
This can explain why it may not start on its own as who knows if the previous owners have done the same thing , current that’s too much = heat and heat increases “resistance” . If a part “resists” too much, it won’t fully pass the require signals to start the bike and run it effeciently.
So, tear down the bike until it is on bare harness , smell the harness for burn marks and ECU = these are so important that trying to find a new D-ECU’s or Harnesses for a GV specifically is difficult as it is (Since Korea has now moved on to GV300S and GV250DR 2021).
Replace these right away to be safe;
- HT Caps
- Ignition Coils
- Spark Plugs (CR8E only!)
- Stator Unit that’s for DELPHi
- Regulator that’s for DELPHi
If in doubt send an email , ill find the parts for you but hey….. you’re lucky it didn’t go on fire. Years ago regulators were posted online by Hyo owners of them going on fire.
Again sorry for the bad news but it looks like we doing an electrical reset and you can’t trust half the old electronics anymore. Things like stators / regs / coils are usually not “user-fixable”
