DR650 mini-backfires - normal?

[scott785]

Hey there,

I've got a 2012 DR650SE that makes small backfiring type sounds (pop pop pop) when engine braking, or after closing the throttle when riding downhill (leaving the bike to coast in gear).

My 2007 KL250H (Super Sherpa) does the same but it doesn't stress me out as much because it's older and has much higher mileage. Oddly, my first bike - an abused 2001 KLR250 - hardly ever made such sounds.

Is this normal on a relatively new DR (only c. 5,000kms on the clock)?

Or, have I or the previous owner done something wrong?

Many thanks,
Scott
