Backfire - anything to worry about?

[Wonko The Sane]

Just managed to backfire the ZZR when starting it

Had just ridden about 20 miles in rush hour traffic filtering and queuing before stopping for 10 mins and trying to re-start it.

My alarm's a bit dodgy so I tend to hold the starter while pressing the alarm remote a couple of times until it fires

ended up with a backfire, followed by an intermittent beeping from the alarm before the alarm went off (with the bike still running)

The alarm being daft I'm not worried about, I don't have a little lick of flame burning away inside my exhaust or anything daft like that?

Got a small lick of flame with the backfire

I regret to inform you that there's a fair chance that your balls have swollen by 2 sizes and you'll need new underwear.

I've seen videos of people getting a little jet of flame out of their exhaust and then a lick of flame coming out the end of the can and not going out, just want to be sure I'm not going to go out to my bike in the morning and find it burnt out against the end wall of my house

I did ride home after sorting the alarm

If you have a flame in your exhaust you need to blow it out, do this by blowing in the end of your exhaust. Otherwise the flame can travel up the exhaust into the engine, it can then jump into the carbs/fuel injectors, up the fuel line and into the fuel tank.

My bike spits back so badly at low revs no one likes to be behind me in pre-stage

Ive got a ZZR too, and I managed to get a backfire usually takes some choke to start but it wouldn't turn over. Turned choke off, tried the starter while revving to try force some fuel in and still. Nothing.

Anyway it soon became clear I was a dick and had my sidestand down, my neutral switch/light doesnt work, so of course it wouldnt turn over!

Knocked the stand up and pressed the starter and BOOM!!! Then I rode of feeling brilliant after scaring everybody within a mile radius.

So it probably went bang because you were trying to statt it for longer than usual, building up fuel ready to go kabang?

A few days after I got my ZZR, I was coming back from work at around 4am, there's a nice straight roman road on my route home, so I thought id see what i could get out of it. Going quite fast I flipped what i thought was the main beam switch, turned out to be the kill switch. Cue the biggest backfire of all time. I absolutely shit myself, thought me/a tyre/the universe had blown up. Cue 5 minutes on the side of the road trying to start the bike before i realised. Lesson learned there!

It's fine my bike backfires and sometimes spits a flame if I let off from full throttle in 1st and 2nd, pretty much every time, good fun

You guys never use your kill switch to do 'bangs' when you're out? It's exceptional fun when going past bus stops and BMW drivers.

Ride along with closed throttle, hit kill switch, blip trottle, kill switch on and BANG! a lot of the time you will also get a flame shooting out (length depends on how long a blip you give it).

Note - this doesn't work on FI bikes

You can also work on what my mates call a super-sonic-bang. This is where you do the above but have the throttle open when putting the kill switch back on. This results in a the massive bang and you accelerating away!

Man i need to get out more...

Worse than that, in fact. Mate of mine did one and not only did it tear his can open but a sizeable piece of shrapnel tore off and ripped a gaping wound in a baby's head. Could see the poor thing's brain pulsing within - the mother was distraught, went grey and fainted dead away. Godawful afternoon that was. But it's all part of the biker's lot. We soldier on - and, when trying to remedy electric problems, we solder on too!
