ignition advance unit missing

[japonetza]

Hi XS650 fans, I am new here but i ran out of search options on google. I have 1892 XS650 that i bought as a barn find. This is my first xs650 so there is some learning curve for me. I have two manuals and both say that i have to remove the ignition advance unit, the rod and so on. I want to do some engine work on the head, but when i removed the covers, my engine does not have this unit. Also the port where the wires would go is plugged. the shaft seems rusty like never was anything ever attached there. I believe it came like that from the factory, but nowhere did i find any mentioning that this unit is not needed for my engine. Can someone please tell me if they have some models that do not have this unit?

Thanks

1980 and later have TCI electronic ignition and advance is handled by the TCI box.

'80-'83 US model XS's have a crank timed ignition - nothing under the cam covers

Mike, thanks a lot. For a second i was really confused. I have Clymer manual and they do not mention anything about these differences... bummer... i spent two hours researching this. thank you for the shared knowledge.
