I don't think that would be easy. From what I've read, the 86 sensors might fit the 87-89 engines, but you'd need to drill and tap the 4th...
Something doesn't sound right here. Are you sure your 87 is supposed to be 450-550? That's what the 86 bikes are and I could swear the 87-89 bikes...
How can you have 2 spark boxes? The 2nd gen 86-89 have a single spark box in the tail section. Are you refering to something else? The 1st gen...

The ignitor box could be the source of your bad running and not the carbs at all. :) I had a similar problem with an old Virago I used to own....
Have you checked your idle mixture/pilot screws? I recall experimenting with mine and when I turned them out only 1.5 times I got a weaker...
