Rotor Markings

Ever wonder what the rotor markings other than the "Lazy T" were for*?

I'd a thought center of keyway would have been TDC, but Edge of keyway is probably more accurate.

I guess that's what they intended. I'm pulling mine in a couple of days and intend to look at that. This was a picture I pulled off of the internet, not mine. I'm going to see if a straight edge laid across the center-line will line up perfectly.

edit: I guess I should probably set it up on the surface plate and check it with the height gauge to be more accurate. Geez, that's more work than I signed up for when I woke up this morning...

Try to move the ignition pickup coil a bit.

Yes that is the only way I have heard of also.
We can elongate the holes to see if we can get enough, but does it really make a big enough difference to worry about...that I do not know...?

With less than 37HP stock - 50HP "Built to the Hilt", I'll suggest, It Ain't Worth Messing With!

Tighten those trigger coil/pick-up coil/cps sensor screws Which You Did Apply some Loc-Tite Blue to, and Forget Them! Just my opinion.

I have not posted any truly useless information in a while; let this suffice.





Them Kawasakians is purty good at machinin' when they wants ta be.

The TDC mark on the rim of the rotor is keyed to the edge of the slot on the crankshaft...

Looks like them lines are even a degree or two out of line!

Even more reason for Willys to make more Degreeable sprockets!
But one should use a piston stop and properly mark / remark TDC.

In the top photo? That's parallax error from the camera angle. I drew the red line to show that the TDC mark was set right at the horizontal center-line, then scribed the mark on the hub.

I'd take a better picture for you, square on to the rotor, but I tore down the set up and installed the rotor. As an old-timey machined parts inspector, take my word for it.

Kawaski's marking is dead nuts. Not to say that the slot on the crank can't be misplaced, but I checked mine and it's correct. On my motor they did well with this.
