Spark plug options

[STiForester]

I have a Tecate A2 and I am looking for the best plugs on the market to run on my bike. Any ideas?

ngk iridium's have worked the best for me. A friend of mine has a kawasaki 100 enduro with a g3 motor in it. They were known for fouling a plug every time you got done riding. but since we put in the iridium plug it has not fouled in over a year.

Yea that's what I was thinking about getting or the g series

Why was he fouling so much? Could be wrong jetting issue also

I run an NGK Iridium also. I run E3's in every other motor from my truck to boat motor to chainsaw.

NGK end of story. If your fouling plugs it's not the plugs fault. Look at the air fuel ratio, oil ratio plays a part in the two stroke process also...

I researched the g3 and g4 kawi motors, they are known to commonly foul plugs. the auto mix the oil and fuel, but I think the coil wasn't powerful enough to give the right spark vs oil and fuel jetting is stock, and it runs great, but is just something they do. Even people who were premixing their fuel still had fouled plug issues so is just something with those series of motors.
