When I shut off my BA there is a "poof" in the exhausts after a couple of seconds. Sounds like a gas BBQ going out. One of the members mentioned this was a vacumm leak. How do I find the leak and how do I stop it?

Mine has always done that, increased when I put on new pipes.

On my bike it seemed to have started after I drilled out 2 sets of baffles.

Mine has always done it also, before and after mods. A soft "thump thump" when I shut it down.... I keep waiting for a cymbal but haven't heard that yet.
More flags
More fun!

Mine did that with cross over lines on the the carb vaccum ports. I removed them and just plugged them and viola "thump, thump" gone. Interesting result

Probably just more noticable.

Mine did the same, but I thought it was "cool". After the big bore and carb kits, mine just says "f you" then gets a cold beer.
