try a fresh set of plugs first to make sure the ones you got aren't bad if you haven't already, then start testing the electrical stuff backwards from there. plug wires, ignition coil, CDI, switches, wires, etc. look of broken wires, loose connectors and so on. might be something as simple as a connector came off as you reassembled everything. you didn't say if ya still got the TORS still on, so if ya do, check all that stuff too cause if a part of that went bad that will kill the electrical system on ya too, like it was designed to.
