    You know the answer to that Bob.

    At the very least, should be checked.

    How do you figure out where to set the timing, other than factory settings? Is there a way to check other than running the engine,obviously you cant use a timing light. so how do you know its right?

    How exactly do you use a timing light, I'm sure there is already a thread about this, but I dont really feel like searching.

    i mark the flywheel with different color markers before i put it on and then time it through the little hole in the flywheel cover . but if it's off you have to take the front cover and flywhell off again to reset it . it's easier on the domestics you need to remove the cover and not the flywheel .
    I also have bendix holders so i don't have to remove the cover each time

    CDI timing

    You should check the timing with a light. All the specs are in the factory manual, and you will need a dial indicator. (I have kits available).

    Most STOCK CDI's will be fine, as they are timed using the same reference curve at PVL, but if it has been re-programmed by myself or Polaris you should check it. (also a Hotseat, etc,CDI). If I re-programmed it, the factory timing adjuster most likely has been disarmed and will not work.

    Check the timing at 3000 Rpm, and at WFO just before it hits the rev limiter.. Follow Lugs instructions. A difference of two degrees can make or break a good performance package.

    Regards,
    Randy
