Ignition Coil x2 Honda CB600 CB 600 (1998-2011)

I still didn't fit the coils. I took the motorbike to the local motorcycle specialists that after a month they told me the bike was running smoothly. When I picked up the bike, the problem was the same - misfire, loss of power, battery drainage. I took the bike back immediately. My best bet will be the coils. I just don't understand why the garage to whom I paid for 2 hours and a half of diagnosis they didn't' even test the old coils. So, I can't tell you yet if these coils will be of any good for my bike. It's just my best bet.
