On my Burgman 650 the plugs were a PITA. 
Iridium's great claim to fame is durability, so I installed them on that.
I used copper on my old SYM, until the last change.  I could have regapped but I spent a few bucks and got an iridium.

No noticeable change in performance on either bike, but prior experience on my 2k6 burgman and my RAV say the iridium will hold up better so less hassle.

Racing Planet says they have it in their Euro warehouse, but their price is ludicrous.  Maybe ping 'em and see if that's a typo.

Do you hear the fuel pump run a bit when you key it initially?
Could this be a stuck side stand switch?

Admittedly this place is a high, but Shoreline WA (1st ring 'burb N of Seattle) yesterday..

Is this the beastie you're referring to Major?

Been on the books here for years, but pretty much no enforcement.
I suspect it's used as a tack on when someone's pulled for something else if they're being a dork.

From the manual:
• The direction of all weight rolls is same.
The color side is towards to clockwise.

From the interwebs seems the same as well.

And sliders (my preference)

Hey Faber please let us know what ya come up with and whatcha think.

For what it's worth, here in the U.S. I've generally found going a gram lighter's worth the bit of mpg, but I also live in a pretty hilly area.
It's also of note that you can mix weights a bit so if 12 g is too much one way and 13g too much the other, even number of both evenly spaced would yield the equiv of 12.5g.  Fair warning I ain't done it personally, but more 'n a few folks have on various models.  If you try it and it don't feel right swap it back to what worked before.
