No, under the seat there are two "spark units" , The oem label on them are "Oki mps-200". Not entirely familiar with the whole system but the most basic explanation is that the pulse generator sends a signal to the spark units and the spark units send a signal to the coil. There are 2 of them...

I think my issue is going to come down to the carbs running too rich. I got a spark tester and all 4 were able to bridge 20,000v gap on the test so i think that rules out my weak spark/ pulse generator theory. Next week im getting a new valve cover gasket so ill check my valves then too just to...

Could always use some new parts!
