Richride's mid range issues appear to stem from charging system issues rather than any issue with the Gonzo or electrical noise.
The Gonzo box is not something that was cobbled up by a tinkerer in his workshop. It was designed for and used on the Lochin 300 built under license from Suzuki . SE Asia is flooded with the things. If there are problems with the igniter the net would be flooded with complaints about it.
My View Respectfully I don't do this to complain or so Input was asked for and input is given
I don't seek to upset anyone. .. Input is the seed for development
If I understand it right
We have a system A XS650
We have a system B the Gonzo
A has components A(1,2,3.. .n ) Alternator / Wiring / Charging / Ignition and so on
B has the same B(1,2,3... n) Alternator / Wiring / Charging / Ignition
The B system in present days has been tested in a shop some where ,,and mostly there are protective measurements done
against the problems arising in that system B shielding programming decoupling and so on
A -- System has been tested in a shop in Japan in the 70 ies
What happens here as I understand it is that B(4) is taken out off its design situation
B and are moved into the System A . A(4 ) IS replaced with B(4) with 40 years design differences if not 50
which can be entirely different in terms of fex electrical power
Brushes damping and so

If the alternator ( I am not claiming is so but if ) are sparking like a weld at the brushes fex ..It is not necessarily so that the
Micro controller in the Gonzo Box ever was designed never tested to cope with that.
You gentlemen are experienced enough to know these problems
You don't take it for granted that a carburetor from a System C can be installed .
And / Or don't install it without Re jetting Some tweaking
So if you are honest most of you realize that there are perhaps problems involved in doing what you are
doing.
And fine ...nothing strange or Disqualifying .. These issues happens in Many development Projects
If not all .. Some tweaking and adjustments and the solution is ready Plug and Play
I am no expert but i Know a little and know that micro controllers are sensitive.
The facts are
Two different systems
A and B Both work
Taking ignition box from B and hook up on A --> There are at least 2 bikes I have seen --> Having problems
I have not read it or analyzed ... But There is where I am at .. If the explanation is clear and known
fex Worn brushes or whatnot then it is no problem I got it wrong with poor reading.
If it is right so far then a development engineer would notice those situations and trying to figure out what is going on.
I have not seen any figures on the number of working installations
I know of Jim but not much more and seen 2 different with Problems
Rich has tested rather extensive strategies .And appears to be experienced, Still with problems
