SOURCE: Hi I have a 1995 heritage softail

sounds like you may have an intake leak. with the bike running spray a little starting fluid on the intake manifold but make sure you dont spray it into the back of air cleaner as this will give you a false reading. if the idle changes when you spray starting fluid on the intake manifold then you have an intake leak and need to replace the intake manifold gaskets. God luck let me know what you find

Here is a list of things you can start with:

1. Spark plugs in poor condition or partially fouled.
2. Spark plug cables in poor condition and shorting or leaking.
3. Spark plug gap too close or too wide.
4. Faulty ignition coil, ECM, or sensor.
5. Battery nearly discharged.
6. Damaged wire or loose connection at battery terminals,
ignition coil or ECM connector.
7. Intermittent short circuit due to damaged wire insulation.
8. Water or dirt in fuel system.
9. Fuel tank vent system plugged.
10. Air leak at intake manifold or air cleaner.
11. Loose or dirty ECM connector.

14. Weak or broken valve springs.

SOURCE: What is the correct air

Correct tire pressure - 30 PSI in the front
36 PSI rear single rider
40 PSI rear two up riding

Always refer to the side wall of the tire for air pressure. You may not be running Dunlop tires.

SOURCE: were is the fuel filter

Filter is in the fuel tank attached to the fuel petcock. Check your intake gaskts for an air leak. Get the bike running and squirt some brake clean near the intake seals and see if the bike dies or idle increases, but dont squirt too much to get sucked in the air cleaner. Also check the vacuum lines going from the fuel petcock to the carb for dry rotted or loose connections.

SOURCE: I need to see a

I doubt you're going to find a video of the oil being changed on a Softail. To change the oil on your Softail, look at the oil tank from the right side of the bike. At the lowest point on the backside of the tank, you'll see a large hose coming from the tank and running down behind the transmission. The hose comes back out from behind everything at the lower part of the frame behind the exhaust pipe and looks like it connects to a crossmember of the frame at the bottom. Feel underneath the crossmember directly underneath the hose and you'll feel a drain plug. Remove the plug and the oil drains out of the tank.

Good Luck
Steve

1) Throw a full or 1/2 can of Seafom (found in most auto stores) into the tank, then go riding.
2) if that doesn't clear this up, drain the tank and add new gas, plus half a can of Seafom, then go riding.

Good Luck, Bob

Hi Kmeyer6595, and the usual suspects are:
1. Idle speed improperly adjusted.
2. Intake manifold air leak.
3. Loose low speed jet.
4. Contaminated or plugged low speed system.
5. Enrichner valve not seated or leaking.
6. Leaking accelerator pump.
Good luck and have nice day.

Multiple miss-fire and miss-fire on #5. I would first change the sparkplugs then replace the distributor cap and rotor. There is a good chance this will fix the problem, but no guarentees.
