SOURCE: Adjusting timing on Harley Davidson 1976 sportster

The advance timing should be 35° before Top Dead Center. This is how you find out which mark this is.

Get the rear wheel of the bike off the ground, remove the spark plugs, shift the bike into fourth gear, and remove the timing plug from the left engine case.
Now, take an ordinary PLASTIC DRINKING STRAW and insert it into the front spark plug hole. Do not use anything else or you stand a chance of it breaking and then you'll have to pull the head to get it out. The plastic straw will bend but not break.
Bump the rear wheel in the direction that it turns while riding down the road until the piston pushes the straw all the way up and just barely starts going back down. Look into the timing hole. You should see a timing mark. This is the Top Dead Center mark. Now, bump the rear wheel BACKWARDS until you see another mark. This should be the ADVANCED TIMING MARK. The piston should 7/16" down from top dead center.

On this model Sportster the timing is advanced by a mechanical advance mechanism. These units are notorious for wearing out and not contolling the timing very well. You must remove the breaker plate to inspect this mechanism. Mark the position of the plate before you remove it. If the pins and holes in the flyweights are worn, replace the unit. Replace it with a good needle bearing unit. Replace the points and reset the gap at 0.018 - 0.020".

The starter on a late model Harley is a typical Nippondenso gear reduction type starter. They are all basically the same except for size.
To replace the starter clutch inside the starter assembly requires disassembly of the starter assembly.

I you will contact me directly, I will scan the procedure and drawings out of a service manual for you.
