alf03 Posted October 30, 2009 Share Posted October 30, 2009 I am about to put the bike back together and I am changing the air filter. Would it be worth it to change out the plugs to the iridium plugs at 15k miles? I am not looking for more power just not sure how long the factory plugs are good for other than what the owners manual says. The tank is off so that part is out of the way already.

redxxrdr Posted October 30, 2009 Share Posted October 30, 2009 The manual shows inspection at 16K miles, replace at 32K. I screwed up and replaced at 16 because I couldn't read. At $17.00 per plug, I would inspect and reuse. REMEMBER, you can't gap or mechanically clean these plugs without damaging them. Quote Link to comment Share on other sites More sharing options...
