I've been looking for the adjustment on the balancer. Thanks!
I've been through Toby's site and there is a ton of good info there, but I couldn't find any actual adjustment procedure. The on-line fische show the differences, but I haven't taken mine apart to see it in person.
I went through the rest of the motor adjustments and made a simple wiring harness to start it up without frying anything. It started and ran well yesterday. Got a quick adjustment done on the carbs and it idled fine, had good response and seemed smooth. The motor is smoking a bit, but it hasn't run in who knows how long and I did add a fair amount of oil in the cyclinders for the compression test. Also, I do not know if these bikes are prone to wet-sumping like the old brit bikes.
I've got the extended oil sump so hopefully I've also got the balancer mod
