I've been using Suzuki coils for a couple years and I'm very happy with the way they perform, bought a second set as spares. Also clears up a lot of room under the tank.
i have these in mine, of course you need 2 sets so you have 2 coils spare but i put about 5k on them, they get GREAT reviews and a landed on them because a friend of mine has them in his daily car that that has about 80K on the clock with those exact coils so .... BTW if you think the chinesium is better in brand names vs cheaper ones.... its hit or miss. i believe these are great.
I will as soon as I figure out how to upload a picture.
I haven't figured out how to upload pictures but found an article in resources: Coil over plug mod ( cop ) for standard coil removal by JSHRAM- May 24, 2018. Several pages and pictures. Many people added to the article. Good article.
What version (part number) Suzuki coils are you using?
Sorry, I was mistaken believe I've got Yamaha's R1, I'll check tomorrow and will put in correct information.
Sorry, they're Yamaha's #F9T558 bought of E-bay
Thanks Gerald, I just ordered a set from Ebay for my R3 that's experiencing the problems described in this thread. My biggest worry was frying the ECU with untested coils. I now feel confident that the R1 coils are a good choice.
