I'm at about 6000kms since recall and plan to change them. I usually toss a new set in at the beginning of each season if I need them or not. Once you go to the trouble of pulling them, might as well change them.
Well, It seems the more we ride this monsta, the more it gets less of a monsta, the more often we need to replace plugs, tires, and go for all the performance mods, starting from BAK and PC3, going on with HC pistons, and ending with turbo and some other stuff.. .Not that the Warrior will not keep on making us happy for long years ahead. . .but it's like in the story with St.Andrew with the Dragon, Shakespeare's "Taming of the Shrew" and so on. . .
One Kaw ZX-12 rider said that "the Warrior is a brutal bike". He never rode one. The only one that rode my bike is a fat guy who's really a twisties wizzard. He rides an Aprilia RSV Mille. So the word goes around the sport bikers. .Hehe
No wonder we got 2 plugs per cylinder. I mean, it's part of nature. The harder you ride it, the faster you deplete the plugs. Lol, this should be the Quote of the Day on Discovery Channel. . too bad they do not have anything on Evolution and Darwin lately.
