Yes it will work you might have a different design which I doubt but the function will be the same

possible 3 and 4 pulsar coil bad.or a grounded coil wire.

most are in tight and 1 and 3/4 out

Under the seat, in the fuse box.

Have you checked the points? Be sure to clean the point contacts, also she may need a new condenser if it is not new (they break down with age). Did you clean the carbs? Did you mess with any adjustment screws? post back with what things you have done.

use a noid light to show pulse at plugwire,or just unplug a sparkplug wiire plug it to a extra sparkplug let it ground on metal(frame or engine) spin the engine over watch for a spark on the plug, red is a weak spark blue is good.

The 1981 Suzuki GS750L does not have contact points. It uses a signal generator instead.
