The right spark plug! - xthib1 - 27-06-16
Hi guys!
In my owner manuel (00 fzs 600) I can read:
Except for G, F: CR8E, CR9E...
For G, F: CR7E...
Stupid question, wtf "G, F" is??

I know.
Re: The right spark plug! - xthib1 - 28-06-16
But... what does the country change??? I don't get it.
Re: The right spark plug! - BBROWN1664 - 28-06-16
Its to do with emissions and average altitudes and other local variances.
Re: The right spark plug! - xthib1 - 28-06-16
Ok. Hmm... weird as all my french buddies seem to put CR8E on their bikes.
Re: The right spark plug! - YamFazFan - 28-06-16
Don't Germany and France have E10 (10% ethanol) petrol?. I think it burns hotter than E5. Maybe that's one of the reasons why the manual recommends a hotter plug?.
Edit..the general consensus on the web seems to be that ethanol burns cooler than petrol :\
Re: The right spark plug! - xthib1 - 29-06-16
They have, but most of them don't use it.... My question is still open ^^
Re: The right spark plug! - BBROWN1664 - 29-06-16
xt, your question was answered. You may not believe it but it is true. Try contacting Yamaha if you need confirmation.

Says what they stand for in that NGK manual
F conical seat
G Fine nickel alloy centre electrode

In the specifications chapter of the Foxeye manual it says except for D,F (Deutschland, France?).
In a separate reference to fuel it also mentions ZAF as an exception. I've looked that up and it came up as the abbreviation for South Africa.
I reckon BBROWN1664 is right on this xt

Hate to say but this makes much more sens to me.
Re: The right spark plug! - BBROWN1664 - 30-06-16
Also, standard "San Plomb" in France and the equivalent in Germany is 91 Octane whereas unleaded over here is 95 which means different combustion temperatures.

So if 91 octane burns cooler (?) it could be an explanation for why a hotter plug is specified.

then the plug reference would be cr7eg or cr7ef
they are country reference codes as has been stated previously.
