Would one of you kind chaps let me know the reference number for the NGK iridium spark plug for the Tenere please.

BTW is it worth the replacement?

I have on order the DNA stage 1, 2 and 3. I have yet to find out if it is worth also purchasing a 'power commander'. I can't see why the original CPU can't be updated via PC?

Sorry to keep asking these questions but how else does one learn?

Very best wishes to one and all,

Ryland

Hi Ryland,

I honestly believe that the Tenere runs fine without specials spark plugs or additionnal tuning.

it takes some knowledge to start playing with advanced engine setup.

But as you seem interested

iridium: CR7EIX

Hi, Ryland,

I have a 2007 XTX, but as you know, the same engine.

I use an NGK Iridium spark.

So, the normal spark is NGK CR 7 E.

If you want use an Iridium spark (better, according to me), the code is :

for NGK : CR 7 EIX

for DENSO : IU 22

Ciao. Gianni.

G'day Ryland

I think the iridium spark plugs are total BS. I have used them in my WR and all they seem to do better is "fowl easyier" but yet you pay more money for them, so i went back to normal ones and happier for it.

If you sat there and said "i can feel the difference" then you would be fooling yourself. In a bike like the tenere where the eingine is not highly strung, i can't see the need for them at all.

Just keep asking yourself this question when buying motocycle stuff.... "is this a marketing ploy"

cheers
Reg.

I agree on the spark plug comments - mine works and I have a spare just in case it doesn't.

The ECU question is probably one for Kev, but I do not think it's possible to connect to the standard ECU - let alone re-program it..

The PC enables the user to create custom maps, so can be fine tuned to any bike. If you're going for the full air box mods, then to get the best from the engine you'll need a free breathing pipe (I have the X Racing single can) and at least the Kev fuel mod (I've got this too). Kev is working on the 02 eliminator, but even with the 02 sensor in place and connected Kev assures me the fuel mod is working fine. I've not done enough miles yet to really comment, but I can say that compared to the standard set up my K&N/Snorkel removed/X Racing/Kev's fuel mod spins up better and is much crisper - sounds better too!!!

Without going into the engine and making changes, I'd suggest the Scottoiler too. You can lose power through an unlubricated chain.

I use an Iridium plug in the TTR, it can be a pig to start at times and with the Iridium plug it certainly fires up eaiser. But there is no noticable difference to a standard one. Given that there is no problem with the 660 motor firing up, I'd keep my money for other things.

Tripletom did some research to find a programable ECU, and I think (form failing memory) it was something like �2500. The stock Yamaha one isn't programable easily, although anything with software is vulnerable to being cracked, the costs would be silly and this could easily raise a bug in another area.

For the <�300 for a PowerCommander, combined with the DNS upgrades it offers very good value for money. You could spend �500 on cans with less improvement.

There is the Kev-Fuel-Mod that has some good feedback and very cheap. Basically this fools the bike into thinking it's colder than it is and adding a bit more fuel (with the DNS filters it runs too lean).

I have the DNS Stage 2 and PC-V with the map supplied by Simon - it works very well indeed and I'm very happy with the return on my investment (and if I ever get a newer Z, I can move it to the new bike!)
