Had a bit more time to look at things. F5Dave came round and we started it up and looked and poked a bit and lit it up with a timing light. Dave made suggestions and went home to finish his bike and I got into following the suggestions. With the multiple minor tweaks done I fired it up again. Runs pretty sweet. Revs up OK, too slow on the back-off but that could change with timing/advance curve/jetting changes. It all looks close. Lack of money says ...
