I bought some new plugs for my 140cc 3W twin and was wondering if I should gap the new plugs. Anyone know what the proper clearances are for the them? I assume its manufacture spec.

i gap all my ngk-6m plugs at .018" i believe the range is .015 to .020


*edit I got that info from Flying Giants http://www.flyinggiants.com/forums/f...-plug-gap.html

The default range is .020 min to .024 max unless there are instructions with the ignition. These instructions should be followed.
