electronic ignition issue (2014)

Thanks to every one for all the help, great forum with great people.
The bike is running quite well now, turns out that when I put the tank on it was pulling the throttle cable on the right cylinder hence it was never going to be set up correctly.
The only issue I have now is that I am getting the odd flame from the right cylinder and it sounds as if its missing a little bit.
Carb is set up the same as the other, timing is correct, any ideas ?

Some electronic ignitions vary the revs that they reach full advance at, eg could be in the range of 3500-4000, so when setting the timing at full advance, do it when you see that the ignition stops advancing, rather than looking at the rev counter.
+1 on resistor plug caps, the NGK ones are cheap as chips.

Electronic ignition systems have to be timed static at the full advance position and it is then up to the system to retard ( delay ) the timing dependant on the rpm.
I have never understood why Commando timing is 28º full advance when for many years the Atlas & 650SS were 32º. Commandos are only an Atlas engine with the 650SS compression ratio. The other confusion is that on all my Commandos I have carefully checked the timing marks with a dial test indicator and degree plate and found that the actual 28º timing shows about 31º on the primary cover degree plate, a simple manufacturing error or did the development engineers find the engine ran best at the displayed 28º which is really about 32º and left it that way ?
