Was this a jap spark plug? I can't remember the last time I've seen a jap plug fail.

Yep, NGK made in Japan. Thats why stupid me went and got a coil, i cleaned up the plug anyway, and presumed it wasnt the plug, cause i have never had a plug fail.

Hmm, a bit fishy how the problem moved with the coil. Still, a fix is a fix.

I'm half looking into the so-called "stick coils" for the GPX and maybe eventually the RC17 (as if I don't have enough to do on them already).

I put stick coils on my ZRX1200, and ZZR1200. Worked well, with a harnesses from a ZRXOA member.
