Aftermarket Spark Plugs

Hehe I never tried them my bikes have always ran great with ngk so why change. And we have 5 different bike dealers so ngks are easy to come by

Interesting. never went with an American plug in a Japanese bike, at least since I could afford the correct plugs.

Interesting Kaw used the same plug as the GS, in a cooler version. You could also use B8ES as they'd be a little hotter spark.

My 81 KZ750E also used the B8ES plugs. The GPz is a higher compression motor with a slightly different squish area, which is probably why they went one range cooler.
Since my current compression is ~10.50 - 10.75 I believe I will stick with the B9ES plugs or switch to Nippondenso W24ESU. So far the NGKs are fine and I have two sets of spares, so I am good.

I believe the W24ESU is same as B8ES. Cooler would be B9ES or W27ESU.

Hmmmmmm,thought all my bikes where D8EA.Was thinking of getting a bunch of them.Looked it up,the 1000 takes B8EA

But would you put a ngk in that Pontiac? :/

I run NGK TR6 plugs in the Firebird. Quality plug, doesn't blow out under high pressures.

Ed, I'll have to double-check that number if I ever decide to switch to NDs. Thanks.

I have heard Champions suck in motorcycles..I just get the NGK when needed.

Got champions in mine, they ignite the fuel, so that would mean they don't suck

I don't wish Champion spark plugs on my enemies.
Worst spark plug brand on the Planet!

JMOE,

This. I've never had good luck with them, they always seem to foul out after a few thousand miles. My MGB calls for them stock, after my previous experiences with them I've always used NGK's or Delco's. Never had a problem with those. The GS get's NGK's.
