How To Set Timing On Harley Evo

The Harley-Davidson Evolution engine — also known as the Blockhead — was introduced in 1984. It replaced the Shovelhead engine that had been in production since 1966. The Evo, as it’s commonly called, powered every Big Twin model until 1999, when the last of the Twin Cam 88 engines rolled off the assembly line.

The Evo is a two-valve V-twin with pushrod actuated overhead valves and hydraulic lifters operating in an oil bath. Valves are adjusted by means of screw-type adjusters located at the base of each rocker’s arm.

  • Harley Evo has a timing setting that is specific to the model and year of the bike
  • The best way to find out what your bike’s timing should be is to consult your owner’s manual or a professional mechanic
  • Once you know what the correct timing setting is, you will need to adjust the engine’s idle speed so that it is in line with the new setting
  • This can be done by turning the adjusting screws on the carburetor or fuel injection system until the desired idle speed is achieved
  • With the engine idling at the correct speed, you can now set the timing by loosening the distributor cap and rotating it until the mark on the rotor lines up with where it needs to be according to your manual
  • Once everything is lined up, tighten down the distributor cap and enjoy your newly-timed Harley Evo!
How To Set Timing On Harley Evo

How Do You Set a Static Time on a Harley Davidson?

Assuming you would like tips on how to set the time on a Harley Davidson: There are two ways that you can set the time on your Harley Davidson.

The first way is by using the up and down arrow buttons located on the left side of the instrument cluster. You can use these buttons to scroll through the different options until you find the one that says “Clock”. Once you have found this option, you can press the right arrow button to enter Clock mode.

From here, you can use the up and down arrow buttons to adjust the hours and minutes. Once you have set the time, you can press the left arrow button to exit out of Clock mode. The second way that you can set the time is by using your voice.

If your Harley Davidson is equipped with Voice Recognition, then you can say “Clock” after pressing the VR button located on your handlebar control module. This will take you into Clock mode where you can use your voice to adjust the hours and minutes.

To do this, simply say “Hours” or “Minutes” followed by a number (for example “Hours 12”). You can also say “Set Time” once you have finished setting the time in order to exit out of Clock mode.

How Do You Set a Plug Timing?

Assuming you are talking about a spark plug: Spark plugs fire before the piston reaches the top dead center. The timing is set so that the spark will ignite the air/fuel mixture just as the piston starts its downstroke.

If the spark fires too early, it will create excessive pressure in the cylinder and could cause engine damage. If it fires too late, the mixture may not ignite at all, or may only partially ignite, which can lead to engine knocking.

To adjust the timing on a car with an internal combustion engine, you’ll need to adjust the distributor. The distributor is what sends electricity to the spark plugs in order to create a spark.

To do this, you’ll need to loosen the screws holding down the distributor cap so that you can rotate it. Then, rotate it clockwise or counterclockwise until you hear a change in engine sound.

Clockwise will advance the timing and make the engine sound faster, while counterclockwise will retard (delay) it and make the engine sound slower.

How Do I Set the Static Timing on My Electronic Ignition?

If your car has an electronic ignition, you may need to set the static timing at some point. This is not a difficult task, but it is important to do it correctly. Here are the steps you’ll need to follow:

1. Find the specifications for your particular engine in the owner’s manual or online. You’ll need to know the correct position of the crankshaft and camshaft for your engine, as well as the firing order.

2. With the engine off, disconnect the negative terminal of the battery. This will prevent accidental electrocution while you’re working on the ignition system.

3. Remove any covers or shields that are blocking access to the distributor cap and spark plugs.

4. Locate Top Dead Center (TDC) on the No. 1 cylinder of your engine by turning the crankshaft until the piston is at the highest point in its stroke and then aligning the timing mark on the pulley with TDC on the block surface or head gasket surface where it meets the block deck. In most engines, TDC will be marked on the harmonic balancer or flywheel; check your owner’s manual to be sure where it is marked on your particular engine model before proceeding further. If you can’t find TDC visually, you can also find it by feeling it by rotating the crankshaft back and forth until you feel compression in that cylinder when you turn it over by hand with a wrench (be careful not to get pinched!).

How Do You Adjust Ignition Timing on a Motorcycle?

The ignition timing on a motorcycle is adjusted by changing the position of the spark plugs in relation to the piston. The timing is measured in degrees before or after the top dead center (BTDC). To adjust the timing, you will need to remove the spark plug and insert a feeler gauge between the plug and piston. Adjust the position of the spark plug until you achieve the desired timing.

Harley Evo Timing off

If you have a Harley with an Evolution engine, you may find that the timing is off. This can be caused by a number of factors, including:

1. Incorrect valve clearance. If the valves are not properly adjusted, they can cause the timing to be off.

2. Worn or damaged camshafts. Over time, the camshafts can become worn and damaged, which can affect the timing.

3. Worn or damaged crankshaft bearings. Like the camshafts, the bearings can also become worn and damaged over time, affecting the timing.

4. Loose or damaged timing belts/chains. If the belts or chains are loose or damaged, they can cause the timing to be off.

Harley Davidson Timing Mark View Plug

Harley Davidson Timing Mark View Plug: If you’re a Harley rider, then you know that one of the most important aspects of maintaining your bike is keeping an eye on the timing. And, while you can do this by removing the timing cover and inspecting the marks on the gears, it’s much easier (and less messy) to simply use a timing plug.

With a timing plug installed, you can simply glance at your engine to see if the timing marks are lined up correctly. There are a few different types of Harley Davidson timing plugs available on the market, but our favorite is the clear acrylic plug from JIMS. This particular plug has an O-ring seal that helps keep oil and debris out, and it also has a built-in magnifying lens so you can easily see the marks on the gears.

Plus, it’s easy to install – simply remove your old timer cover gasket and screw in the new plug using the provided hardware. Whether you’re performing a routine check or making adjustments to your ignition timing, having a Harley DavidsonTiming Mark View Plug is essential for any serious rider.

Harley Evo Points Timing

Harley Davidson’s Evolution engine, also known as the Evo, was first introduced in 1984. It was a V-twin, four-stroke engine that replaced the company’s Shovelhead engine. The Evo provided increased power and reliability over its predecessor and would go on to power Harley’s motorcycles for nearly two decades.

One of the most important aspects of maintaining a Harley Evo is proper points timing. This refers to the timing of the spark plugs firing in relation to the position of the pistons in the cylinders.

If the timing is off, it can lead to engine damage or poor performance. Points timing should be checked periodically, and adjusted if necessary. Instructions for how to do this can be found in your Harley’s service manual. With a little time and patience, you can keep your Evo running strong for many years to come!


If you have a Harley Davidson Evolution engine, you may be wondering how to set the timing. The process is actually quite simple and only takes a few minutes to complete. First, find the top-dead-center mark on the flywheel.

Next, locate the timing pointer on the left side of the engine. align the TDC mark on the flywheel with the timing pointer.
