How do you set the satic timing on a 74 Norton 850 comando?

Answer 1

it's been so long since I did that. i think you'll need a TDC gauge, a timing disk and a meter so you can detect when the points have opened.

If you are careful you can use something else instead of the TDC gauge but if it breaks it is a head-off job to remove it!

Static timing should get the bike running then you'll do a strobe light timing to get it accurate. full advance 28 degrees

Answer 2

I don't know about your Norton. This is how you do it on a Jap bike with points.
-First adjust the point gap on each set of points.
-Turn the motor until the points are open the widest.
-Adjust the point gap. 0.014" - 0.016"
-Repeat the process for other sets of points.
-Connect a test light or multi-meter (set at same voltage as battery on bike) between the points and coil (in series - as in points, test light, coil).
-Remove spark plugs so the motor turns easier.
-Turn on key.
-When the points are closed, the light is on, or meter shows battery vlotage.
-Turn motor in same direction as when it's running.
-The light should go off, or the meter drop to zero volts, exactly when the timing mark lines up.
-Adjust the point's timing plate to achive this.
