I'm not proficient in BoyerBrasden, but many others here - including Jan - are, so...But I could hear a clicking sound, so I continued to do it, and then at least one of the plugs started to spark, but not the other.

If it currently has all-thread for the cam (advance) rod, I'd want a original or reproduction rod too and new cam bushings. The reproductions are available from Mike's - seen statements they're a bit long in stock application, so you'll want to properly shim it - with 1/2" ID shims - for clearance on the BB rotor (yours was hitting).Since this is my first XS650, I really don't know what original parts I'm missing from the Boyer conversion or what I'd need to buy to make sometime else work. Guessing at the bare minimum the original rod.
Yes; on stock 360degree motor, Left is at TDC exhaust and Right is at TDC compression with the cam dowel @ 12 O'clock
Learning everyday: Thanks Jan, I've not tried to retrofit an advance rod in late-model cam and didn't know there could be an issueRegarding going to points.. -->
I'm thinking that the bore in these later cams may not have been finished or sized as exactingly as the earlier ones because Yamaha knew they weren't fitting bushings in there anymore.
