ask at halfrauds or a bike shop, lots of different types of spark plug, would keep to same size and heat rating unless your runing a really tuned engine, probs won't really notice a difference though

I dont think id trust anyone in halfrauds to tell me if it was raining or not if they were standing in the carpark!

you wont notice anything from an iridium spark plug, just use the spark plug thats supposed to be in it

Dickhead · Nonce

ktooms use a ecm plug if im right its a shorter stubbie plug

Katie-Jay · DTR Respected Member

im not expecting any power gains etc, I just wanted to know why the KTM uses an iridium and the DTR doesnt, and would it have a longer life and produce a more efficient spark.

You've hit the nail on the head Katie-Jay - longer life and more efficient spark.

Great, so does anyone know the NGK ref for the iridium plug compatible for the DTR?

Damn I have a spare BR9EIX for the KTM in the garage

A br9 eix will work fine in a dt. It's only a slightly cooler plug than a br8 eix everything else is the same.

I beg to differ, according to the trusty haynes (page 94), and my local Yamaha dealer, its a BR9 recomended for the DT.

Your BR9 is correct, NathanDavies is wrong

fray · Guru

In the manual I've got it does say br8 es so nath isn't wrong either can be used.

My appologies, in my manual it says only BR9 for DT
Its says either BR8 or BR9 for TZR

Dickhead · Nonce

as a dt is not a tuned engine as such i prefer to run a 8 as it runds cleaner imo and les chance of it fouling up

fray · Guru

I always use an 8 aswell find it runs better as robin says.

As I earlier explained, appologies if I had it wrong, I was going off reference of the trusty haynes (page 94), and my local Yamaha dealer, which stated a BR9 is recomended for the DT.

BR8 or BR9 for TZR
