Backfiring

[Rosey]

Hey guys

Does backfiring cause any damage to the bike? It doesn't happen very often but it's pretty loud when it does and only when I'm going down gears to slow.

Thanks

Are you sure it's backfiring and not just popping?

If the exhaust has a leak it will suck in air on over run and pop off any excess fuel, if the butterflies are closed then airflow is reduced and fueling richer...

You can blow the guts out of a muffler if it's really bad, try maintaining a small throttle opening and rev match the downshift, see if that has any effect otherwise check for vacuum and exhaust leaks.

I get some popping out of my akrapovic when I trail throttle on overrun.

I play with the throttle to make it happen as much as possible. I have been doing so since 2007, about 80,000km ago.

It's still fine. :-P


If you have some shitty can like a 2 brothers ymmv. :-P

As a flag marshal I've observed that 2 bros cans also have a tendency to detach themselves at Wanneroo
