Hi,

I'm after yet more invaluable advice - this time on plugs.

My bike is non-standard Z1B in that it has been bored out to 1075cc, has a Yoshimura 4-1, K&N type pod filters and has 117.5 mains. Any advice as to the best grade of plug to use would be really appreciated.

Thanks again.

Nippon Denso W24ES-U

NGKs have become really shite in the last few years and as soon as they get a bit damp, petrol or fuel they break down and cease to be use nor ornament.

These guys offer a cracking service and are as cheap as chips.

Wingman, Denso every time :!:

As for heat grade (if thats what ur also after) equivalent to standard NGK '8' is fine.

Usual advice to go a grade colder (9) if thrashing it a lot, or hotter (7) if lots of slow town work :wink:

I run the Denso Iridium plugs (one grade colder than standard) with no probs so far :twisted:
