I got some NGK Iridium spark plugs for the Heritage.
There was a warning not to gap these plugs as it would
break the tip. Had never heard of this and I'm uncomfortable
not checking the gap . Has anyone had experience with
this . The plugs were ordered specifically for the '04 Heritage
but how can you be sure of the 0.040 gap other than sticking
it in and seeing if/how long it works.
Thanks .
