If you jumped at the stator then that means the sator,cdi,trigger and coils are good. If you plug it all back in and there is no spark, then there is an issue with the switches or the wiring harness. First just start by bypassing the TSS/kill switch. I show how to do that in this video:
If it still runs poorly there is always the chance that the key switch is bad. Lastly, if it still runs bad then you need to bypass the whole wiring harness. Wire your key switch directly to the stator's 2-nonyellow wires that would normally plug into the wiring harness. Then turn the wiring harness plug 180 degrees and just plug in the 2 yellow wires from the stator to the 2 plugs that are supposed to go into the wiring harness. The 2 other plugs on the wiring harness (the ones that would have plugged into the other 2-nonyellow wires coming from the stator where your key switch now goes into) plug into nothing. Watch this video to the end and I show how to do it:
