You can go to halfords and get CR8E as that is the OEM plug for every Hyosung sold since 1999 , so always stick with CR8E no matter what.
Also, while there, ask then for a spark plug tool that fits CR8E plug , get more than 1 tool, incase Tool #1 is being awkward in the frame , get Tool #2 that may be shaped different to avoid hitting the frame or ancillaries attached near the engine.
Do that first…
Ride a little bit , come back.
Send us the picture of the FRONT and REAR plugs = We will know they if the HT caps are on the way out (common! hence we only use NGK Race ones that’s NOT plastic as i would NOT use plastic caps, they will crack!) .
Also have a multi meter ready , and we will send pictures on how to test your own coils to get some hard proof to see if the coils are OK based on readings.
You could do way better than your current mechanics at this rate , good luck!
