Which spark plugs do people recommend to use? Stick with the factory ones or should I change to a different type? Do the stock spark plugs require gapping or are they pre gapped? |

I like the iridium ones, some people say they don't notice difference, when my bike was stock, i did notice a slight difference, they are supposed to last longer, and cost double the price. |

I just got NGK iridium plugs at NAPA. $2.50 for regular NGK, $7.50 for NGK iridiums, so they are expensive. Haven't tried them yet, so I don't have an impression. I did have to adjust the gap slightly. I would check the gap on any new plug. |

Al Lighton cautions to be VERY careful if you adjust the gap on iridium plugs. The center electrode is so small it's very easy to bend which is not a good thing. |

My '06 has nearly 20k miles on a set of NGK Iridium plugs; bought from American Sport Bike. Hot or cold (ambient or engine), the engine starts and runs fine; still get 50 MPG consistently. |

I use the regular NGK's. 20K on them. Just pulled them the other day and cleaned them up(some light sanding) put'em back in. Bike runs great. |
