Hi Anonymous, This one is a tuffy since I don't know what year your bike is. If you have an early model you could have a bad run/stop switch, ignition sensor, ignition switch, ignition module. If you have a late model could be crank positon sensor,electronic control module, but on the late stuff you can pull up trouble codes on the odometer and that would at least point you in the right direction. Good luck

SOURCE: REPLACINGTHE REAR TIRE ON A HARLEY DAVIDSON 2008 HERITAGE SOFTAIL

Down and dirty way - take it to the dealer and have them install a new tire....

The hard way: place bike on bike jack and remove rear wheel by removing the axle nut and drifting the axle out of the wheel. Derail the belt/chain and drop the wheel out of the brake caliper. Remove valve stem to deflate the tire. Get a set of tire spoons and a 12 pack of COLD brew cause working with tire spoons is no FUN! Pry the bead loose with one spoon and the work your way around the wheel prying the tire beed to the outside of the wheel. Repeat this process for the back side of the tire (in the same direction as the first side so the tire will come off the wheel. Reverse and repeat to install new tire.

By now you will be loading your wheel into the truck and heading to the HD shop. It just really isn't worth the hastle to save the $25 or so to have this job done.

Align wheel with new tire on it with the brake caliper so that you have one shoe on each side of the rotor (you may have to actually remove the caliper if your pads are thick. Install your belt drive/chain drive and then lift the wheel to insert the axle through the swing arm, the chain tensioner and wheel. Reverse
on the other side. Place axle nut on axle and torque to about 80lbs.

Good to go.

The fork oil is a very specific job needing a manual and a special tool, I don't want to insult anyones mechanical knowledge but if you have never done it before, best to take somewhere else. Engine oil on the other hand is easy, the drain tube to any softail is on the right side by where the frame meets the swing arm, has somekind of plug in it. Start and run bike for a little while, long enough to get it warm but not hot. Remove fill plug and then remove plug in drain line. Using a peice of cardboard or something put in between filter and frame , directing the oil to your drain pan instead of where ever it goes. Put 1 qt oil back in (after everything is reinstalled) start the bike and make sure the oil light goes out, when it does shut bike off and fill to the point that when it is standing upright you get a little oil on the tip of your finger, over filling may result in loss of oil cap from pressure (been there)

1999 harley davidson softail standard won't start back fires


You have a wasted spark system and you are getting fuel. Probably you need new spark plugs as even if the old ones look good and might spark out of the engine it appears they will not spark properly under compression pressures and the fuel that remains unburned is ignited when the spark plug fires on the exhaust stroke when there is not pressure and therfore teh backfires.

2004 FXSTI softail standard fuel pump does not come on when I turn key on and when I try to start It has no spark.


Hi Anonymous, the CKP sensor needs compression to send correct signal to the ICM/ECM, make sure both spark plugs are in heads and use a grounded third plug to check for spark or hold spark plug cable close to spark plug in head. If still not getting spark the usual suspects are:
1. Fouled spark plugs.
2. Battery voltage below 8.7 volts, loose or broken battery cables especially ground cable to frame.
3. Loose connection at ignition coil or plug between ignition sensor and module.
4. Spark plug cables in bad condition, shorting / leaking, spark plug cable connections loose.
5. Faulty ignition coil or ignition / electronic module
6. Failed CKP, CMP, MAP or BAS sensor.
7. Faulty ignition switch.
