The problem you describe is very commonly 2 things at play here:
– Battery is too small (life is shortened) – It must be size 12-14AH (Yuasa YTX 14BS is good)
– Regulator = All hyosung branded regulators use the old “diode” tech (1970s), so once they get hot , they start to die rapidly which is annoying. It is probably #2 most annoying device after the side stand switch, but i digress lol!
We use proper upgraded ones from Kawasaki (hit “Shop” at the top menu to see what it looks like)
When the above ^ is changed over. Keep a good eye on your Stator (genenerator on the left side of engine casing , next to sprocket cover) it gets quite hot (more than the old gen) , it should be doing 75v-99v healthy if you’re handy with the meter to test it.
All charging & ignition starts from this hot device before it tells your regulator to charge your battery & your cdi to send sparking energy to the spark plugs to fire harder. = So all these are kind of intermarried!
If the the bits above ^ are sorted. And you still hear some buzzing sounds or clicking noises when you press “START” , change the solenoid (common) it is that ball next to the battery , it controls starter motor. If starter spins slowly (battery & solenoid are the culprits generally)
Sometimes the RC dash will flicker or spaz out all over the place when Key is ON or START is pressed.
Hope that helps.
