What exactly is backfire. What causes it to happen. Is it preventable. Is it harmful to the bike. Every now and then my 09 SE5 drops a bomb , mostly on the left. Other than that 7800 miles running like a charm.

There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

From historical postings, I would guess the "Y"gaskets are going bad. My SE5 started backfiring at about 8 thousand miles.
Cause can be from a bad Y gasket(s) to lean mix (performance pipe and/or high flow air filter). Too much of it will ruin your muffler and premature need to repack the muffler (or it just gets louder ... which is not exactly a bad thing
