I have a 04 Volusia that ran fine but needed a new air filter. So put in new Bikemaster af only thing I changed now it runs rough and feels real cold blooded on start up. Goes to a certain rpm then feels like it runs out of gas missing and popping. Shift to next gear and it pulls again.Only thing changed was the filter.The holes on the filter seemed like loose fit so I put o-rings on to try to get a better seal and seemed to help some.The filter looks like it seals good.Not sure what I am missing.:idea: Any ideas.
