Guys - Just off my ride in the NC mountains, and wanted to ask a question about backfiring. I have Muzzy Black Stainless midpipes and slipons, which has always had a nice, light popping on decel. I have no problem with that, and don't think the bike does either. But on my trip, one morning in northern GA, I fueled up, along with the 3 other guys, at the lone gas station in Suches GA. I seem to remember they had non-ethanol fuel, but I think it was 93 octane. From there, over the course of the next day or so, the bike backfired with a big loud boom/bang from time to time. Usually just once and it was done for a while. it happened ~20 times total. It even happened after fueling up at other stations. If I recall right Kawi calls for 90 octane fuel, so 93 was high.
I think I was the only one to fill up from the nozzle I used. And the other guys had no such backfiring.
My bike's ODO is at 9,400 miles, and I have not yet changed the original air filter.
Thoughts? Suggestions? Concerns??
Bad gas? Air filter? Something else?
Thanks all ...
