I hated Champion spark plugs until I proved to myself that they definitely worked better than NGK in 2 stroke motors.
Better idle, quicker throttle response.... difference you could feel and measure the idle increase with digital tach.
I ran both ND and NGK plugs in Kawasaki's. We had brand new Kawsaki's come in with ND plugs one year.
I have ND's in my bike a the moment too, gapped at .028" with stock CDI ignition system. Could have gone Dyna, no thank you very much.
Ran a lot of Bosh and Autolite in my cars. What do you care in your car except it starts, get's as good a mileage as it can and you don't think about the spark plugs for at least 70,000 miles.
Here's Greg Copes spark plug tips.
Spark Plug Gaps
When running a Suzuki or Kawasaki with a Dyna-S and high performance coils set plug gap at .026. When running an MSD or Dyna-4000 Ignition system set plug gap at .018.
Spark Plugs
Racing motors usually require a heat range one colder than stock. We recommend NGK plugs. For a Suzuki GS1100-1150 use a D9EA. For a Kawasaki KZ 900-1000 use a B9ES. With a Dyna-S ignition and aftermarket coils run a gap of .028. If your vehicle has a MSD box or Dyna 4000 ignition run a plug gap of .018 - .020.

depends on whats being dumped in the tank! :laugh:Take those same plugs. Put 1500 miles on them, and than do a side by side comparison, and I bet you could tell the difference.

I wanted to try the NGK B8EV but hard to find.... Can special order but screw that.... ~ $5 each no big deal....
Then I found some info they're discontinuing.... Ah well, B8ES have been working just fine.... @ $2.50 each, hell throw them away every 3-6 months pending how many miles you put on them....
Cheap insurance....

I'll bet you $50 that if anyone was given a KZ to ride with the spark plug label covered, they could not ride the bike 10 miles, then tell you if it had Champ, NGK, ND or Bosh plugs in it...
Maybe put in one of each and see who guesses what. :lol:

I haven't done the coil mod yet, but I've been told with the coil mod you don't even need spark plugs. Ed
