Champion vs NGK

hello give tim green a ring at Green spark plug Co phone 01477 532317 ask for tim Hope this May Help

Mark,

Probably a totally odd idea, but how about running Champion N7Ys? Ran them ever since I had my first Commando- now 35 years- road and race, never had a spark plug problem. Part# 06-2348 from Andover Norton if you can't get them locally.

Sorry, I forgot- the easy solution is not what people write in forums for. So pester any number of spark plug specialists instead and stay well away from the obvious answer........

Hi

I used to run my Commando Metisse with 10.25 C:R using NGK BP7ES (plus Boyer Ignition) and it used to start first kick. I've worked on a couple of bike recently where the owners were convinced they had an ignition problem only to find thatone of the carburetterpilot jets or passage wayswere blocked. It's worth a try!

N:B The concentrics that don't appear to have a pilot jet do (of sorts)- it's hidden awayin the passageway behind the pilot jet screw.

Regards.

Ian.

I suspect that the next move by governments will be to ban the sale of all non supressed ignition components.Then classic bike owners will have something to worry about.Its already illegal to use a nonsupressed ignition system,and its the next logical enforcement move.Dont expect any announcement,it will be done quietly with the cooperation of manufacturers and importers.Regards John.

No idea. Have used a lot of N7Ys over the years, never had a single one with problems.

Its not unusual to have brand new plugs right out of the box be bad, I used to do some auto mechanic work on the side for extra money & ran into it from time to time, mainly with Champions I am sad to say

Like motor oil, every one has afavorite, I like Bosch now.

The only problem I know off is if one severly floods the carb at first start with brand new plugs and thus soaks them in petrol for their first spark. They just die an instant death. Remember that from our rotary racing days and, no, we did not use Champion plugs in the rotary racer.

Put a Bosch plug in a Triumph (or Norton) and see how long it works. On Triumphs (real Triumphs, pre-1985) I give them a week at most. No idea why it is so, it just is!

I have used bosch plugs in my Nortons for years? Perhaps a different part number?

I've used N7YCs for thirty years and never had a problem. I've only ever replaced them when they became tatty looking.

I've only used NGKs in 2-strokes so it's not really fair to compare. The NOS KLG M80 in my 16H is doing just fine ! !
