Due to the hot weather, and lack of a decent air conditioned shed, I have been a little, nay, very dis-interested in even popping the seat off the bike to check the air box.
So, let me tell you the funny story...
Scenario:
Launched off from traffic lights quickly. Note: This means big throttle openings. Bear with me, I'm building a picture.
Engine almost died, like it instantly went massively lean, but recovered a couple of seconds later and got on with it.
However, this was accompanied with sudden serious loud induction roar on opening the throttle.
Rode carefully home as I suspected something had come off the airbox. Too hot to do anything. Park her up and ride the Honda for a while.
It's the end of February now and is getting closer to reasonable riding weather and after all, I'm tired of the cruiser-style of riding.
Great idea

So my punishment for being a lazy bugger and not popping the seat and pulling off the air box cover was obviously having to pay someone else to do the work. I'm starting to sound like Intrepid Ken now...

So, onto the problem

I've been around engines in bikes, cars, trains, earth-moving equipment, chain saws, ships, trucks for a long time, but I have never heard of an engine inducting a plastic bag which subsequently blocked the air filter completely. No air flow... felt like extreme leanness to me...

Due to the high throttle opening at the moment of the induction of said plastic bag and the associated high air flow, the engine sucked the entire paper filter element and the offending plastic bag into the air box. This of course allowed the air flow to suddenly continue unabated into the engine, but with a loud induction roar. The engine recovers and gets on with going.
Thankfully I was sensible enough

And so the story ends.
So if you're happily accelerating away with high throttle openings when your engine suddenly dies on you like it was suddenly extremely lean, then an instant or 2 later it recovers, but is suddenly spruiking a loud induction roar, check your air box for a plastic bag and make sure your air filter is still where it is supposed to be.
