Hey loud (aka kz550 god) Or anyone else who knows

is that collar supposed to spin?

The above quoted picture shows the cam rotor in an older points ignition system.
But which uses the same advancer as used in later models.

Here's the advancer without any type of rotor:


Am thinking the 1981 KZ550 LTD has Kawasaki electronic ignition (located under the points cover) with I.C. Igniter (located under the seat or side cover).

Here's the Kawasaki mounting plate with two stationary pickup coils, which also shows the pointed rotor (instead of a cam rotor) that's attached to and spins with the crankshaft between the pickup coils.



Note the pointed rotor:


Good Fortune!

On engines where the ignition system located under the points cover has been replaced with a Dyna-S ignition, the same advancer is used along with the Dyna-S mounting plate which has two fixed pickup coils, and a Dyna-S rotor (with a small embedded magnet) that spins between the pickups.

When the Dyna-S ignition is used to replace the Kawasaki electronic ignition, the new Dyna-S backing plate is mounted and the Dyna-S rotor is mounted. And the I.C. Igniter is no longer used.







Good Fortune!

I still am unclear here as to what should turn

the spring'd weights should be the only thing to actually "move" ya? besides of course the crank

The crankshaft turns when the engine's running, and both the rotor and the advancer turn along with the crankshaft as the rotor spins between the pickup coils.

The pickup coils don't move.

The backing plate doesn't move because it's screwed into a fixed position.

As the advancer spins behind the backing plate, the weights on the advancer move outward with increased rpm, which causes the rotor's cam/point/magnet to reach the pickup sooner and thereby advance the spark in relation to the crankshaft position.

All I can say is WOW... fucking WOW!

The advance r was rusted a bit, after a night of 3-3-6 and a little coaxing by hand I got the advance r to spin/actuate slapped it back in my bike and went for a test run... and lost a mirror! lol holy smokes the power difference is UNREAL 55-60 in 3rd WHAT! lol redline snaps are NUTS too Loud your are the man... without a doubt thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you

Patton thanks for clearing up my confussion

Now for the fun bit, i'll need to source a new advancer at some point in time as one of the tabs that help rotate the cam is broken off but it seems to run fine as is...


Phreak

Did I say thank you?

That is great to hear...

And many thanks to Patton for picking up the ball and running with it (advancer-photo-wise).
