do i have to remove the fairing and the radiator to get to the spark plugs?
Or do i need hands of a 5 year old to get in to that little hole

Is there a trick to it

You CAN do it with either a rubber insert type box spanner or a magnetic one but I always drain my radiator and swing it towards the headstock to limit knuckle scrapings!
Fit QUALITY plugs,(I use Iridiums) you`ll not have to do it too often.

Hello, NO , unscrew the rad bolts so access is easier and use a spark plug socket & ratchet WITH extension bars.
It's a 10/15 minute job once you've done it a few times..

OH and when you've unscrewed the plugs i've found it easy/easier to take the plug out with a fingernail.

Yeah, just swing the rad forward (no need to drain it really) , but it does help if you have slim 'girlie' hands or are a practicing proctologist

Oooo get you, proctologist?
It`s easy I can do it with one finger!
