Spark Plug Gap Size

[cosborne]

I need to know what the gap size should be for my '02 400ex. Thanks. (its NGK)

NGK plugs come pre-gapped, should not have to gap them. but depending on the plg, most are around .28 or .30

i've never had a plug that was gapped right yet. all ways regap your plugs to make sure they are right.
