Did you get a chance to take pics of your plugs ?
The OEM Caps are not great as Hyosung doesn’t make them, but some outsourced company called “Golden China” . Using NGK Caps does help a lot and they rarely fail with sparking issues as bad caps can cause weird misfiring issues especially when its hot as its buried deep in the engine heads.
You want the rubber NGK caps similar to the ones on our store. Don’t buy “Plastic NGK Cap” , totally rubbish those ones. (Just like regular CR8E Plugs & LASER plugs are recommended but don’t touch “Iridium IX Blue Box” as they don’t like IX plugs much)
