400ex PLUG GAP

[tahoe97]

What should the spark plug gap be set to on a 2001 400ex with the below mods????

thanks

I believe it's 0.6-0.7 mm. Plug gap has nothing to do with mods. Most motorcycle plugs come already gapped, at least that's what I was told. Every plug I've ever bought was correctly gapped, but I always check to be sure.

For the metric impaired it's .024 - .028 inches.
