    I was going to change out my plugs and also keep an extra on hand in case I need it. Anything special I need to be aware of? In the cowling they state which NGK plug and then I believe I read tighten to 18nm. My current plugs have some corrosion and there is some salt spray under the cowling with slight rust on a bolt or two.. I was going to change plugs, rinse salt off then use Corrosion Block under the cowling.

    opinions?

    Make sure to gap 'em according to the specs before installing.
    Other than that, sounds good to me.

    All yamaha ngk plugs are pregaped. No gap-ing needed.

    I stand by my previous recommendation.
    Doesn't take but a few seconds to be sure.
