I have a question about the stock plug, it came with one of those special racing NGK's. This is the same plug as the RM's but it's a #9 not a #8 R-16918B-9 is stock. On kawasaki.com partsdiagram it lists an optional plug R7376 in 8-10 heat ranges. Anyone know the difference? '03's has B9EIX's why the change from this plug?

because bad things happen- lots of 03s had the plugs come apart and ruin the engines- just ask marcus, but be aware, it might make him mad :eek: - there is a thread in this forum somewhere if you search it! ;)

I would use the plug reccomended by Kwak, the 03 had problems with the BR9EIX and the 04 has more compression than the 03.
