Reply To: Hyosung Aquila GV 125S running problem Apr 21, 2024 at 10:03 PM #13044 Luka👤 Member🖊 Topic Author Topics: 1Replies: 6 Hello in the end the problem was with the spark plug caps/connectors. Apparently when original ones heated they didnt insulate anymore and spark was jumping to cylinder head. I swaped them with ngk ones and bike runs like new.
