What should the gap be on a Harley Davidson spark plug?
Never use a coin or disc style tool which can damage the electrode, especially on Iridium plugs. Most Harley models with electronic ignition call for a range of 0.38 to 0.42 (0.40 average) gap, but consult your owners manual for your specific model. CV Performance carries a full line of spark plugs for Harley and Buell models.
How big is a spark plug on a motorcycle?
A decent tool kit will have them. Don’t get confused between thread size and socket size. Motorcycle spark plug socket sizes are usually 16mm, 18mm or 20.6mm (21mm will do). Whereas the threads are usually 10mm, 12mm or 14mm. When it comes to motorcycles, access is usually tricky, so my tip is to buy a magnetic spark plug socket like this one.
What should the spark plug gap be on a NGK?
The recommended gap is the “sweet spot” for most riders, excluding heavily modded engines and aftermarket ignition systems. We have witnessed evidence on engines that carry a ccp north of 180, or so, that .035″ on the NGK’s we use, will show more power, across the board.
Why are spark plugs given a ” range “?
I {Heart} Hookers. This is why you’re given a “range” for your gap. The plug will work fine in that range, but begin to falter, outside of that range. If the gap is too small, there isn’t enough room for enough of the air/fuel mixture to get between the electrode and ground strap, so when the plug does fire there is a chance nothing will ignite.
