59bisquik Posted May 31, 2011 Report Share Posted May 31, 2011 I just bought a Banshee thats been sitting a few years. It only had a little gas in it, and I added just a bit of fresh gas to get it to start and run. It has some old Answer or Toomey pipes, supposed to have a newer top end on it with a dune port. Carbs look to be stock and it has a cone filter in the air box. When I start it up, it backfires out of both pipes while its running. Sometimes even while kicking it over. I used the search function and everything I found was related to one cylinder backfiring. Any ideas on where to start looking for both cylinders backfiring? Could it have something to do with the old gas? Or am I looking for an air leak or electrical gremlin? Quote Link to comment Share on other sites More sharing options...

sleeper06 Posted May 31, 2011 Report Share Posted May 31, 2011 IO would do a pressure test and a compression test to make sure the motor is tight and the rings arnt frozen,seals go bad if something sits 4 long periods and rings can get stuck in the lands Quote Link to comment Share on other sites More sharing options...
