Hey so I recently found out that one of my coils is arcing along the coil rather that the spark plug, I think this may be due to a faulty coil so I just want to go along and replace coils and spark plugs but am having trouble finding parts the Plug is ik16 I believe and can’t seem to find the Denso 129700-4800 where have you guys been finding replacements? Also is there a way to make the coils more solid I feels as if they wiggle to much and may be loose. Thank you in advanced!

 

Just get rid of it. Mine started doing that stuff after one track event. The coils are common in street motorcycles. Liter bikes.

 

is there really any difference between stock and these, I’m pretty sure I got magnecor wires laying around but I’ve had the fab9 since I bought the car

 

They are gsxr coils, plug the denso number into ebay, and you will find a bunch.

 

why are they all used, are they discontinued or something?

 

You could probably call a Suzuki dealer directly if you want them new. My guess is that most vendors won’t waste their time trying to sell these. The Suzuki buyer population is tiny, and sport bike engines typically have a short life compared to cars. The engine is probably done well before they need new coils. If your plugs are “wiggling”, there should be a rubber o-ring that wraps around each coil. Position it at the same height as the top of the valve cover so it’s snug. You can get replacements at a hardware store usually.

Fab9 COPS we’re originally designed for NB1s that had bad OEM coil packs that die early on OEM ECUs. For any other models, there probably isn’t a lot of benefit. In the old days, you were forced to buy a whole coil pack and bracket for several hundred dollars. I think now, you can buy one coil if you know which one is bad. So the pricing model is cheaper and OEM can make more sense than maintaining a Fab9 kit. There are too few buyers of this kit to really do a long term review and cost compare them to OEM.

I picked up the Fab9 COP and have had a great experience with it. But when you own a CAlifornia NB1 and bad OEM coil packs ruin a $700 pre-cat or Expensive CARB-approved catalytic converter, the cost question changes dramatically.
