The clocks are working OK. In fact it was all working OK until I touched it, downhill from there.There is a guy in Washington who can rebuild your clocks. Does great work but he has a "Real job"and it takes time. You can contact him at g.poirier.ohc@att.net. He has done several for me.
Check and see if the stud that is next to the pushrod tunnel has broken through. Easy enough to fix if that is the problem. I had one on a bike I bought with low mileage. I first thought that there was a head gasket leak but that wasn't the case it was a casting flaw and when they drilled and tapped the hole it broke into the pushrod tunnel. Good thing I bought 2 head gaskets.
If you want to you can contact me off list at Norton_je@yahoo.com
Cheers
