Spark Plugs

[Pommie]

I just put some Iridium plugs in the old girl just because I didnt know how old the others were. Bikes done 60K now and there were iridiums in there already so not originals obviously. question is how often would you change them ? Dont ride particularly hard but dont hang around either.

im curious too.
I reckon every 60,000.
!
They should be 100,000 plugs shouldn't they.

If not I think I'm due.
Look like a bastard to get at too?
Or just lift the tank?

Just found this link which advises changing standard plugs at 12000km's

But no mention of Iridiums

The change schedule on Iridiums is at 25k I think.
I have just hit that mileage and the bike is purring along very smoothly.
I might buy a set and just have them handy in case I need to swap em over.

I change mine every 20,000 - just an easy number to remember and do all the other servicing as well as a matter of course ie valve clearance etc plus change oil every 4k ..or so

Changed mine at 46000, they looked old, body coroded & tips black as.
Easy to get to, lift the tank, remove the airbox & pull the coil pack straight up & off.

I went to an NGK twin electrode copper over iridium as a mate recommended them & he used to spanner on Yamaha Austria WSBK, so they can't be too bad.

Baby's been purring away beautifully on them too I must say!
