Lining up the points can right?

    I was wondering how to line up my points can. I recall back when I had points on my old CB450 that you had to hook up a light with alligator clips to the points and the other end to the + on a battery. Idea was that when the points closed the light would come on. I don't see why I can't do this with the G/S bean can?

    Hook it up, turn the flywheel to S, and rotate the can till the lite comes on. In theory it would be perfectly timed, no?

    I'd say it was adequately timed , ready to be strobed.

    I think this would give a more accurate time than a strobe?

    Not necessarily since things can be different when in motion.

    Also, check the full advance since that's more important than the retarded setting, and that's difficult to set statically with the points-in-a-can system.

    I did that when I hooked up my can. Datchew called it 'statically timing'. We did that, then checked it with a strobe and it was right on.

    No, since the coil fires when the points open, it's correct statically when the light goes off.

    At idle or close to, yes. But worn advance mechanisms will change that fact. So when the engine spends most time at full advance, that is where you want the timing spot-on.

    Edit:
    Read your post incorrect Anorak.

    I installed the points can today and wanted to verify that the install was done correctly. As the bike is not ready to fire up yet, I used the static method.

    This is what I did.

    Ohm meter set to ohms. One lead on the can output, the other to ground

    rotated engine until S was in the window timing mark. Then rotated the can until I lost continuity. Tightened it with no continuity and less than a millimeter to make contact again.

    Is this right?

    Sounds right and will start the engine no matter what. But you need to check with a timing light once you have the engine running, at idle and full advance.

    I also ran a single wire up to where the coil will live. Probably 16ga. Is this where the wire is supposed to go?

    If you're talking points wire then yes. And originally it is a black wire.
