Hey Marcel,
Spark plugs, caps, coils, battery are all fresh new. He tested them twice after installing and on different days after riding & rain exposure, and they’re healthy so can probably rule that out, although they will probably be triple tested.
He also messed with the clutch sensor and the kickstand sensor as both were randomly activating and shutting the bike off and that’s also fixed now.
My main suspicion is also this: “I would be suspicious of the stator ? It is easy to put the wrong one too or that the pulse sensor seems to hate the cold (ECU thinks dead signal recieved = cut sparks)”
Problem is that if it really were the stator, then I wouldn’t be able to ride it at all? I’ve also read about the CKP, although its weird because this has never been a problem and suddenly is, right after it comes from the mechanic, I guess that’s bikes in general 😀
There was also some weird stuff done to the bike, especially the alternator, apparently it’s got some bigger material in there, mechanic says the regulator its using is from a 650 like a vstrom. That’s not the main issue, there was some wiring disconnected that was meant to be connected to the battery’s negative node, and they’re also doing some weird bypass straight to the battery that I did not understand unfortunately. All I know is that he reconnected that wire. I’m still a greenie on this bike world but might the regulator be slowly draining battery? Anyways I’ll leave the regulator here.

P.S: The mechanic test rode the bike after he fixed it and the guy was truly mesmerized. Said its much funnier to ride than other bikes in the category like the bmw 310r or the ninja 250 (it was the first hyosung he rode) so yeah that was cool to hear lmao
Anyways thanks Marcel, never forget ur a legend!!
