Coils for KZ1000-J engine

So... I've been having some ignition issues recently... I replaced the spark plugs (they were... just gone)... and it cleared up a lot of my issues, but I'm still having some issues.

So I'm on Z1 Enterprises' webpage looking at coils, and I'm uncertain what to get...

I don't need anything super fancy right now. I just want to fix my backfire and erratic spark issues.

I'm not sure about your specific model but looking though the 1000J manual located on this site suggests the coils are 1.8-2.8 ohms so you should look for coils in that range.

Ok, but... coils are one thing I've never replaced, so I'm unsure what to buy on Z1 Enterprises...

Is that what I'm going to need to get then? It's t he only thing mentioning ohms that's in that right range.
