So it has been about +5,000 miles since I redid some of my 1977 KZ1000A.
Mainly for this discussion, a W 1075cc 10.25:1 piston kit and head rebuilt valve job with parts.
I also bought a couple new 3 ohm Dyna coils and a new electronic DYNATEK ignition system.
I installed the new coils, 8mm plug wires and 4 new spark plugs right after assembling the engine,
But I did not install the DYNATEK pointless SS system.
I just cleaned the points, realigned the gap and set timing with my strobe to break in the engine.
couple years layer:
The engine still runs fabulously after all this.
No leaks, no nothing, GREAT fuel economy... etc... so I never got around to putting the DYNATEK in.
Yesterday I decided do it! Yes, after over 5000 miles of not checking anything in the ignition.
BUT... I did check it yesterday and found this...
No burned points after those + 5000 miles.
I burnished them anyhow.
The two snubbing condensers checked at .235uF to .265uF. ( I do electronics as a job and have a very good capacitance meter).
BUT.... the 2-3 cylinders points visibly arc a bit with the engine running.
Points gaps were both still around .32mm to .35mm so I did nothing there but 1-4 cylinders were retarded about 3-5 degrees from 2-3 at around 2500 rpm-3000 rpm.
Bur the timing marks of 1 and 4, as viewed with the strobe light, jump all around at east 5-7 degrees!
The engine has a little blubber with no load on it at around that same speed.
If I rev the engine the timing marks stabilize to within the thickness of the timing marks.
.
Does this sound like a worn out advance mechanism, a bad retard spring, shot pivot points.... worn out pins, elongated holes... bad points them selves?
Other then that... this engine runs beautifully!!
And I did not install the DYNATEK yet. I won't until I further check out this advance thing.
One more thing... I an stunned at how well the engine ran and has been running on the factory KAW points and condensers for over 5000 miles...when simply set up the way the manual suggests.
