Reply To: Hyosung GT125 turns off while running
Can you do what Simon says?
My BIG BIG suspicion is that you will need to replace
– Stator (not made anymore) so get upgrade kit (we are the only shop for it)
– clutch switch (please) (yes replace it but do NOT bypass it!)
– go to your Kickstand. Cut the switch. And bypass it. (Join wires) and waterproof it. We have “bypassed” kickstand switch.
This kick stand switch is very annoying for 99% of hyo riders 😡😠😤
We do not ever sell it. It belongs in the bin lol. Go bypass that switch.
– new regulator. Upgrade it. Do NOT buy Chinese ones. They go on fire!
New stator means new regulator. Do not mix old and new stators / regulators because you will have problems again. Your old stator could be dying because old regulator is killing it. So need to replace both of them
– Battery. Yes. Replace it again. With new stator kit and new regulator. Only use YUASA YTX 14BS (GENUINE) from garage. Online batteries can be old-new stock or fake yuasa. Becareful shopping. Do NOT buy uncommon brands. I trust these brands YUASA , VARTA (German) , UNIBATT (used on MotoGP bikes)
Questions for you in regards to electrics:
– Did you test coils? Are they changed?
(Coils are common fault if spark plug can is bad causing shorting / damaged sparks out of HT wire then coil is damaged)
– do you still have OEM caps?
(If yes, replace them with NGK caps)
(Rubber NGK caps only as plastic ones will crack like the OEM ones)
– What spark plugs do you have? (CR8E? Or did they change your plugs to different ones?)
– Can we see the plugs(?) (Checking fuel mixture on the plugs , heat damage on threads , etc so pictures will help)
Again… Do what Simon said before following me.
It could just be simple things they overlooked like rusty contacts need cleaning and love
