 Well, let's think about it... 
 
 What causes engine backfire?
 When the exhaust valve opens, the
 mixture isn't done burning so it ignites
 the unburned fuel in the exhaust system
 and causes a loud bang. ... As with
 backfiring, coughing or spitting can
 also be caused by a bad ignition
 system, such as cross firing, which
 sends a spark to a cylinder that has the
 intake valve open.
 
 If the engine misses during a switch
 operation, while running, then perhaps
 the coil is not getting enough current
 to charge the coil momentarily.  That
 give a moments time to flow a little
 unburned fuel air into the exhaust
 system and then ignite when spark is
 restored. The white blue wire, running
 back to the solenoid to provide full
 voltage to the coil during starting is
 not in play. But the wire that comes
 from the tach to switch position 2 is
 as that is what provide coil charging
 power when running normally.  What
 could drop the voltage enough to fail
 to charge the coil to sufficient
 voltage to fire? The ignition switch is
 in the run position so that comes
 directly from the B post on the voltage
 regulator, The B post has the
 generator to battery charging wire, the
 main lighting switch and panel light
 switch via a connection to the 
 main light switch.  Looks to me like the
 best trouble shooting would be to
 remove the red wire or power that runs
 between the main light switch to the
 panel light switch. Start the engine
 and let it come to temp and then switch
 on the panel light. If it does not
 backfire as it did then the source is
 somewhere in that panel light system.
 The before shutting the engine off try
 the mail light switch. If it
 backfires then, the problem is in the
 main light circuit somewhere. Next
 step, while running is to remove the
 dimmer switch blue wire. That will take
 the dimmer switch and head lights out
 of the equation. If it still runs when
 the lights are turned back on then that
 means the problem is from the dimmer
 switch to the head lights
 somewhere.   Put the blue wire back on and try the
 main light switch again. If it fails
 then the part of the wiring at fault is
 from the dimmer outward, maybe the
 dimmer has a short internal of a lamp
 connection that fails momentarily after
 powered then opens again. 
 
 Once the area has been isolated then
 get after the search for failed parts
 or connections. 
 
 Hope this helps!

 Group----Electrical problem for
 sure?????  My tiger backfires when I flip
 any switch on the dash.  I think
 it might be the ignition switch shorting.
 It also dies when idling. Anyone have
 this problem before?  Cause?  You all
 have been a great help in the recent
 past for me  and I am looking forward
 to someone being of help now. 
 Thank you.  Russ
