i got champion ra6hc plugs, that m,r put in wen i got it serviced, just wondered what the ngk plugs would be, and also wondered what make of plugs have u got in ur monnie?

Why not use the irridium (EIX) ones - many motorfactors have them in stock & they will cost you the same as a dealer charges you for Chumpion ones.
We run them in all ours (road & race bikes with no probs) - and they are the same for all the 2 valve monsters

Well have just had a brand new NGK plug fail on me, so went back to the old iridium ones gapped to 1mm.
