Plug Gap?
Hey everyone, need a little help, it's an easy one.
First let me say I'm new to the forum and I am not a mechanic, I'm a computer guy, but I'm eager to learn. Title says it all. Starting with a little simple maintenance before I take her out for the season, going to change the spark plugs and need to know the plug gap.
Got a 1996 FLSTF, bone stock as far as I know, was told it may have been jetted (?) when the previous owner installed V&H short shots but not sure.. I've searched the forums and Google and can't get a straight answer. Hoping my fellow EVO owners can shed some light.
Thanks!

First welcome to the forum.
Second get a Harley service manual for your bike if you plan on working on it.
Set your gap at about 40.
If the bike is running good I wouldn't worry about the jets.
If this bike is new to you I suggest you change all the fluids so that you know what is in there and that it is good.

I kinda figured he would get that as all plug gap tools that I have seen are marked in thousandths.
If you have seen one marked in mm, inches, or BitCoin I would be very interested in seeing it.

When I first got my '96 Evo I pulled the plugs to check them. They were auto-lite plugs gapped at front .025, rear .030. The bike started and ran fine. I set them to .040 and didn't notice any difference. I guess it's not as critical as the manual would have you believe. As plugs wear the electrode wears down ,so you gap gets bigger. I would think a smaller gap would give you a hotter spark, as the electricity doesn't have to jump the bigger gap. Either way it didn't seem to matter on my bike.,,
