    Fuji Flywheel Questions

    I have pictures here of two different fly wheels from two Fuji engines of different years and sizes. Both engines have the same timing at 3000 rpm, 24*. Both flywheels pictured have the keyways lined up exactly. My question is why don't the magnetic trigger blocks line up? Why does the bottom flywheel have a longer trigger block? My last question, why does the bottom flywheel have the extra, small trigger block and in only the one spot? I know that "trigger block" probably isn't the correct terminology but I think you get the picture.

    Thank you, Clayton G

    The top one with the smaller blocks is for a analog CDI, the one on the bottom is for a digital CDI.

    The one on the top is from 93 or 94 and earlier, the one below is from 95ish and on... Theyre not interchangeable.

    So if I were to use a CDI box from a 96 SLX 780 I would need the flywheel from the 96 SLX 780 also?
