Believe Suzuki switched to twin plugs (per cylinder) for the 2007 model, from then onwards you'd require four to change them all.

there is a service schedule in the manual listing all the jobs needed for a complete service, not seen a tutorial, but it's easy enough, if you have doubts or need advice I'd suggest you get down to Soho one friday evening, wealth of advice available there.

Thanks for that mate soho ?? Dare i ask lol I work in london and there is a type of servicing going on there but not sure its type of servicing inrequire lol

Where is the manuals section im still learning my way round the site?

if you click on the highlighted "Soho" above it'll take you to the weekly bike met detail, as to the manual I'm not sure, might try the front page (click on the top left logo) might be on there, if not just post asking.

Online parts fiche are a good source of info to:

http://www.ronayers.com/Fiche/TypeID..._CYLINDER_HEAD

This gives you the various plug choices available and shows 2 per cylinder. Obviously you don't need to order as Suzuki parts but it gives you the plug manufacturers codes for you to search online. Not bought for a wile now but there were some good discounts online for buying plugs especially when buying four.

I bought plugs from this guy;

when I was changing them about a month ago. It is quite a good price I think.

When you change them, two of them are a bit of pain to get to, other two are easy...

4 plugs. Also tutorial video on Youtube for most of those jobs (can't provide the link as in work). Some of them are not easy to remove/install so take your time and don't strip the plug threads.
