    Spark Plug Question

    So my bike has been running rather poorly lately and I finally found out why. During my recent move something must have fallen or smashed into my right side slightly bending the end of my #4 spark plug. So I've been running on 3 cylinders, go figure.

    Since I'm going to be replacing the plug I figure its a good time to just replace them all. I have a new set of Dyna Coils and should have changed the plugs back when I installed the coils. I'm looking for suggestions on plug types and gap spacing to match my coils.

    Thanks!

    Most folks that go to the hotter coils switch to the iridium plugs. I believe the gap on those is not adjustable.
    Life is what happens while your planning everything else!

    When your work speaks for itself, don't interrupt.

      Well seeing that I'm a very limited budget, I was thinking about using the some plain old NGK plugs. Any idea on which ones I should get? Or does it even matter at this point? I know people change the gap with the coil modification, I'm just not sure how much.
