gs750 ran then wont start

[Guest]

So heres the dilemma I Picked up a nonrunning 1982 gs750 around Christmas time. The bike came with a 4 to 1 drag pipe and header and no airbox so I picked up some cheap chinabay pods for it. Got it to run but leaked fuel out the carbs very badly so cleaned carbs and installed 125 mains as well. As of a couple days ago ran but broke up a lil over 6500rpm. yesterday ran as it only had 2 and half cylinders and now today wont start at all. sounds like its not even trying at all. have spark out of every spark plug wire and valves were adjusted as well. Im just at a loss with this bike. She has really grown on me but its just getting to be more and more like a VDUB which I have also owned as well ugh.. I am almost positive the ignitor box is bad but then I figured I wouldn't have spark either. any and all help will be greatly appreciated

Look at wiring diagram. make sure plug wires go to correct plugs. If you got spark and fuel it should at least start.look at plugs for signs of fuel after cranking. With cheap pods, open exhaust, it will run poorly according to everything that I've read on here, but it will still start. (If carb passages are not gunked up)

What exactly did you do to clean the carbs?

There it is again, the $100,000 question.

I think you are thinking the same thing I'm thinking as the symptoms point in that direction don't they?

I am almost positive the ignitor box is bad but then I figured I wouldn't have spark either.

If it has sparks, the ignitor is igniting.

Clean and adjust the carburetors properly.

Do all of the other neglected maintenance, adjust the valves, take no short cuts. Your new bike is thirty years old, it needs some work.
