59bisquik Posted May 31, 2011 Report 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
mongo Posted May 31, 2011 Report Posted May 31, 2011 (edited) i would clean the carbs , put new gas in and try it again . did you put new plugs in her ? if not you need to do that also Edited May 31, 2011 by mongo Quote
sleeper06 Posted May 31, 2011 Report 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
