Driving to work this morning my VTX 1300 just started doing decal backfiring. Not the super loud 'CRACK!' sound, but just a noticeable amount of soft popping every time I decal. Since I've read enough about this symptom, my first reaction for what to check is a possible leak in the exhaust head connection causing a lean condition.
When I get time this weekend I'll see what I can do to fix this. I invite anyone to comment with their knowledge of this symptom/issue.
Lastly, I read some people saying they did a pair valve mod and it 'fixed' their backfiring, however I don't understand how that would fix a situation where the issue is air being sucked into the exhaust heads due to a loose pipe/seal condition, but maybe in those cases where the pair valve fixed the issue they had other issues than an exhaust leak?
I have the stock acorn nuts on my exhaust connections, so I plan on buying new gaskets and using some washers when I tighten the acorns down to ensure good closure. Those acorns have a reputation of not holding the flanges down as tight as they should.
I'm hoping this is all I need to do because I'll be stumped if it's still backfiring after I make sure the exhaust has no leaks.
