ok bike wont start.
89GS500
- Valves all adjusted
- Carbs cleaned 3 times now
- new mikuni jets, stock and suggested jets for stock pipe and air cleaner.
- current jetting is stock, air screws 2.5 from bottomed
- float height is set at float bowl gasket level
- floats and seats are brand new
- Both cylinders are getting spark when I ground the plug to the side of the motor
- bike has been rewired to have no key or side stand safety switch
- Bike has run before on this wiring configuration
- vacuum petcock has been removed
- single gravity petcock straight from tank to carb
- vacuum ports all capped off
- Tried three different cdi boxes
- After cranking plugs will either be sooty or wet. Also getting intermittent backfiring through carbs and exhaust
