I had a problem recently with plug 4 on mine - all the plugs came out but the new one wouldnt go back in. Ended up taking it to a garage and had a helicoil put in - cost me £50 including them to come out and pick the bike up (was about £30 in actual work) and it was done in 3 or 4 hours 
Since plug 1 is on the outside of the engine (like plug 4 according the the labels on mine) then there shouldn't be a huge fuss about having to get the engine out etc and labour costs should be reduced.
