Back fire

[Skippernick]

Haven't used the bike for a couple of weeks started up fine on sunday didn't rev well until the stale fuel had been used, used it a couple of hours later no problems.
Started up today, no choke fired first time but backfired for the first time i've had, a couple of years now.
Is this nothing to worry about or the precurser to something else? Never had a problem before.
02 model.

mine backfires occasionally - nothing to worry about - did it the first time 3 years ago - just unburnt petrol mate

OK thats just what I thought but i panic when something weird happens as i just see the wife's face when i tell about the amount to fix.

The trick is to lie
