Difference between similar model ignitors

[salty_monk]

Who knows what the differences are apart from plugs/connections??
For example between the 84/85 700 & 83 750 part numbers are different but connectors and box are the same. I cannot see that there can be any major difference between the two....

I can't see that even the 1100 are very different....

Thoughts please

700/750 the same.
1100 shafty box has different leads.
8v. bikes have more timing than 16v.
not the same animals.

My thinking (from looking at the Dyno 2000 setup) is that pretty much any 16v Gs ignitor would work on any other (with electronic advance) as long as you can make the connections.

Same with the 8v but not interchangeable between the two engine types.

Presumably number of pistons needs to match too....

there lies the problem.
fixed advance boxes.
just between you an me and the wall...
700/750/1150 boxes all interchange.
the 700/750 box has a little more lead and will add "some" performance to an 1150.
the 8v. fixed advance boxes to my knowledge are the same boxes.
long story short..
nothing to be gained here.
please don't tell anyone my "interchange" secret on the 700/750/1150 boxes.

secrets safe with me! Thanks. This is pretty much what I expected to hear.
