Unburned fuel in the exhaust system-- igniting . well all is fine and good until that exhaust system blows the mufflers apart, exhaust gaskets, blows back threw the intake and burns out sensor--okay I guess not all well and good. have seen it blow the intake apart---really not a good thing to do.

WTF? Why are you 'high revving' for? Dumping fuel into the system that doesn't have the chance to be properly burned will cause a flow through to the muffler(s) and ignited from heat in exhaust pipe. I have a scooter that has a similar problem, but it back-fires when it's low on fuel, causing the engine to run lean and foul plugs.................it does provide a nice flame for lighting my smokes though.
OH, one more thing, it has blown the baffles out of my pipes also.

Theory is it allows unburnt fuel through into your exhaust, when you restart this fuel ignites & causes loud back fire.
Although lots of fun it won't do your bike any good, I have seen a triumph trident blow all the baffles out of its exhast after doing this too many times!! Expensive repair bill highly likely!!

Don't worry, Setting off explosions in your exhaust system will make the bike run better and people will think you're really cool and smart.

yes...............the practice of intentionally causing a backfire during operation [while it may seem fun] can cause piston or cylinder damage ,.........the theory?..........when you cut your ignition during hi rev.....you load up your cylinder & exhaust system with fuel/air mixture...upon reignition you cause that mixture to ignite.....with a loud backfire......yes it can cause engine damage, to say nothing about your exhaust system!
