    On my phone so prob going to be lots of typos.
    Going to be a pain, but that mark needs to be as close to dead nuts on as you can get it. At that point you could create a mark and pointer on the other end to show tdc. Once you have it, rotate the engine in direction of rotation only until your at tdc. If you miss it, dont back up, just keep rotating until your back to it. The zero movement of the piston at tdc is one reason a piston stop and a degree wheel is used to degree a cam, and chain slack is the reason for only turning in direction of rotation.
    I was studying the pictures again is why i said that about the mark.
    Is the cam rotor keyed to the cam or to the adapter that appears to be pinned to the cam ?

    Cam rotor is keyed to the cam directly.

    I believe the adapter you're referring to is 13061 in the schematic below. If so, that piece acts as the female mate to the bolt that holds the rotor on. It is held in by a little pin, but it does not affect the rotation of the rotor itself.



    Reference the picture of the rotor (below) to see how it is keyed to the cam.

    There is only one trigger wheel available for 15f? Iím not steeped deeply in that level of Kasa Kaw lore but an engine in a box does open these questions

    Interesting idea. There are two different part numbers for the cam rotor (21007-1356 and 21007-3742). I don't know the difference between them.

    21007-3744 and 21007-3746 are the crank rotor part numbers.

    nmpeter - I think you nailed it! part no. 1356 (picture found online) appears to be 135 degrees different than what's on my engine (I'm assuming 3742). I'm going to run with this.

    It's very possible because it was a box of parts as stated. Might run your hin on Kawasaki's website to see if it come up as a jt1500aaf or adf. The 1356 looks to have been used on the adf engine along with the 21007-1346 reluctor.
    Oh the joys of toys.

    I just looked at the cam on an older 1500cc 15f or LX engine I have in parts and the reluctor has a "618" stamped on the end, like yours does.. No other ID numbers.

    I have confirmation on this fix. I ground the nub off the rotor, marked another spot at 135 degrees (retarded), and remounted it. Fired right up.

    New part is on the way. $15.

    Guys (and gals?), thanks so much for the dialog here. Couldn't have done it without you.
