Spark plug gaps?
I'm now armed with four Denso Iridium IXU27 plugs and will fit them this weekend... now I haven't looked at the manual yet, but if I recall on my other bikes Mr Haynes says one thing, manufacturer says another, and unsuprisingly the actual owners have their own ideas!
So... what gap should I use for these plugs?
Cheers in advance!

Well the manual and that link above says 0.7mm... and you never guess what gap they all were... you guessed it, 0.7mm... so at least in this instance fastasfuck is correct!
So anyway its all done... removed fuel tank, airbox (which consisted of a carbon tray and a large foam filter!, and the changed all plugs. There wasn't much crud at the front so should be ok..
One thing I did notice was that the plugs from the front cylinder did have a large amount of carbon deposit, whereas the rear cylinder did not.
