Well, I won't ask why but you can purchase an aftermarket kit to do this with. You'll have to take the sensor plate and "timing cup" out of the timer cavity on the right side of your engine. Replace the timer cup with a mechanical advance unit. Then, you put the points breaker plate in and set the points to 0.020". Set the timing by bringing the front piston to top dead center and align the timing mark in the timing hole on the left side of the engine. Adjust the breaker plate so that the points just barely break at this point. This is close enough to get the engine started but you still need to set the advanced timing using a strobe light. You'll have to change the ignition coil as well. The coil on your bike is intended for use with an electronic ignition. The coil for a points system must have a primary coil resistance of 5-6 ohms. Simple purchase one for an early model bike like a 74 model Shovelhead. A word of advice. If you're going to do this, purchase the needle bearing mechanical advance unit. The others only last a couple of years before they're worn out.

Good Luck

If my 1981 flt has points ignition, then I don't have to purchase a centrifugal advance to convert to electronic ignition. Is this correct?

Hi, Douglas it all depends on the cost of electronic ignition that you purchase most brands use a mechanical advance for cost reasons on some of its models and then offer straight electronic ignition without a mechanical advance for more money if you upgrade to a stock Harley electronic ignition no problem do your homework and find something that you and your wallet are comfortable with check out Crane, Dynatek and Compufire for more information about your issue and free downloads that you will need please visit the websites below, and for specific information or questions, please feel free to contact me at Good luck and have a nice day.

I have a 1979 harley davidson ironhead sportster 1000 cc . I have had 3 condensors, 2 sets of points installed this riding season. What might be causing this issue ?

The '79 model came with electronic ignition and someone has converted it back to a points type ignition system. I'm betting that they did not change the coil. Check the resistance of the primary of the coil. It should be between 5-6 Ohms of resistance for use with points. A coil designed for use with an electronic igntion uses a coild with 2-3 ohms of resistance in the primary winding.

good luck

We have a 93 fxrs with points . we have burnt up 3 coils in the last 200 miles no coveron the coil, new solid wires any one have an idea need help

That's because you have to use a different coil with points type ignition systems rather than electronic. The coil for an electronic ignition system has a primary resistance of 2-3 Ohms. For a points type ignition system, you must use a coil with a primary resistance of 5-6 Ohms. I assume you have a reason for converting to points ignition. I'd rather have gone to a Crane HI-4 system unless the price was prohibitive then I'd went with a Crane HI-1 system for about the same money as the points conversion setup. Don't forget to service the mechanical advance unit about once a year. You need to take it out and lubricate the bearings on the flyweights.

Good Luck

How does the firing system work step by step from the battery to the plugs on a 1994 road king v-twin motor points /condensor

To begin with, a 1994 Evolution powered Road King did not come from the factory with a points type ignition. It came with a solid state ignition system. Harley went to a solid state ignition in their Big Twin engines in 1979. If your's has points in it, it has been converted to that system. So, I'll simply explain how an ignition system works in a general manner.

When you turn the ignition switch on, voltage is supplied to the primary windings in the coil. This voltage builds up a magnetic field. When the points, or the Hall effect sensor in the case of an electronic ignition system, breaks the circuit ground, the magnetic field collapses inducing a high voltage low current pulse in the secondary windings of the coil. This pulse goes to the spark plug via the spark plug wires where it jumps the gap between the spark plug's center electrode and the ground electrode.

Now, in a points type system, the ignition timing must be advanced by means of a mechanical advance unit where the electronic ignition uses electronic circuitry to advance the timing according the RPM of the engine.

I am seeking the points setting/gap for a 1962 auston 6 cyl 4ltr 2.45ton truck hope you can help thanks gary.

If it still has a breaker point ignition system then gap the spark plugs at .032 inch, or .81 mm, and if the distributor has been converted over to an electronic ignition system then gap the spark plugs at .040 inch, or 1.0 mm.

Distributor shaft run-out with point system

I'm a bit confused here. The 1979 Sportster didn't have a distributor. I think 1969 was the last year that Sportsters had a distributor in them. On a '79 model, the first year that had the electronic ignition system, it was quite common to see them converted back to points type ignition. The original electronic system was unreliable and often failed. It was much more expensive to repair the electronic system than it was to replace it with an older points type system.

With that being said, most all the early Sportsters as well as the Big Twins had another weak point in their ignition system, the mechanical advance unit that is behind the breaker plate. The pivots for the fly wieghts will wear out and cause the ignition system not to return to it's proper retarded timing. It is best to simply replace the entire unit. Make sure you get one with the needle bearings in the flyweights. These will last a pretty good while. The standard unit will usually start to give problems within about two years if you ride very much. Before you take the breaker plate out of your bike, make sure you mark it so you can get it back in nearly the same position once you replace the mechanical advance unit. It would still be advisable to check the ignition timing once you get the point back in and set.

Connect your tester to the big thick spark plug lead and crank the engine. You should see a nice big fat blue spark. If you don't disconnect the engine kill button. If there still is no spark you will need to determine if the engine has points or electronic ignition. Most (but not all !) bikes built before 1980 have points ignition. Most bikes built after 1980 (but not all !) have some sort of electronic ignition system. If in doubt pull one of the crank end covers (Usually 2-3 screws) and look ! If you have a battery and coil points system see the points page If you have a points magneto system see the Magneto page. If you have an electronic ignition system see the electronic ignition page. ,,,
