    I did have a little bit of a rough idle but nothing jerky. Wound up dropping one so I decided to replace them anyways. TR6's gapped at .035. . Ill see how it runs. Fun figuring out the easiest way to get the rai on and off. I think taking the filter off everything else is best. Took about 40 mins start to finish

    Please tell me that chip in the top left one was the result of the drop. Lol. Are those in the correct firing order?
