2007 Honda cbr stop running while riding and smoke coming from exhaust
Light flickering may be clue. Probably shorted or loose wire somewhere.
Most likely up-stream from lights and ECU since it affects them both.
Start at battery and measure each junction to lights and ECU
1. pull headlight fuse to not kill battery, put trickle-charger on battery
2. battery-voltage with everything OFF = ???
3. key ON, start/stop = RUN
4. battery-voltage = ??? This is baseline control measurement
5. measure voltage of red wire going into fuse-box, volts = ???
grab both battery-cables and shake them, any changes in meter reading?
grab red wire at starter-solenoid and shake it, working your way to fusebox, any changes in reading?
6. measure voltage of blk/red wire at right-controls connector (start-button input), volts = ???
grab blk/red wire at fuse-box and shake it, working your way to start-button, any changes in reading?
7. measure voltage at blk/wht wire at lo-beam bulb socket, volts = ???
grab blu/wht wire at right-controls connector and shake it working your way to left controls, any changes in meter reading?
grab blk/wht wire at front harness conector and shake it working your way to lo-beam bulb socket, any changes in meter reading?

hey I did a few test today.Before I dig into it I changed the gas out to make sure they’re was no water.It didn’t change anytning.I tested to see if the battery was charging and it was.so we can rule out bad gas and stator or rectifier issue.Could this be a bad fuel pump I hear to prime but could it be possible it is not delivering enough gas.any ideas.
That sock on bottom is not filtre. It's just strainer that filters out big stuff that'll damage pump. Real filtre that removes particles that can clog injectors is built into pump housing after pump (pink below).

New pump may be pushing petrol into clogged filtre. Only way to know for sure is to actually measure flow-rate coming from pump-assembly. This tests entire assembly: filtre sock, pump, FPR and fuel filtre itself.

No big deal mixing. Mobil-1 4T oil has worked well for me. Used it on my VFR since '86. Got over 100K-miles on it now! 
For heavy-duty track use, I like Motorex.Only oil that didn't drop pressure 14-minute into race on ZX10R
