What years were Evo engines?
The Evolution engine (popularly known as Evo) is an air-cooled, 45-degree, V-twin engine manufactured from 1984 by Harley-Davidson for the company’s motorcycles.
Where are the timing marks on an Evo?
Your instructions for static timing call for this in the timing hole. My electronic ignition module static timing called for TDC (vertical line). So just modify the steps I indicated above looking for the advance timing marks rather than TDC.
When do you set the dwell on a point engine?
You read above that the ignition timing is the last thing to set when tuning the engine. Your dwell, and thus your points gap, needs to be set before you get out the timing light. To set the dwell, remove the distributor cap and rotor, ground the coil wire and remove all the spark plugs from the engine.
What’s the difference between a Sportster Evo and an Evo?
There are few differences in the construction of the 883 and 1200 cc Sportster Evo engines, the main one being a smaller bore on the 883 cc version.
Is there a rev limit on an Evo?
But be aware you have no rev limit so make sure you have a kill switch on your handlebar, just in case. The instructions you have are the same as mine, and I would recommend setting the timing with a light after you have it static timed and running, but not 100% necessary.
Where is the reference mark on an Evo?
Point the timing light into the timing inspection hole. If the ignition is properly timed, the timing bar will align with the circular timing reference mark. The reference mark on a correctly timed Evo will appear as a vertical bar through the center of the circle. Remove the timing cover from the right side of the motor.
Where is the timing light on an Evo?
Connect the negative terminal of the timing light to the negative terminal of the battery. Connect the inductive pickup probe of the timing light to the front cylinder spark plug wire. Start the engine, and run it at idle. Point the timing light into the timing inspection hole.
What are the strengths and weaknesses of the Evo?
Acutally, there were a few, John. Post 1991 engines had the always-failing INA inner cam bearing. Pre-1996 engines had the thin axle tappets that failed and ruined engines. Hence the “B” lifters that came out, to fix the issue. Then there’s the pre 1996 base gasket leakers……
