Normal or not normal for the 800GS

I have a 2012 f800gs with only 1400mi on it so far. I got it in Novemeber of 2012 and never had a BMW before. I noticed since I got it that it slightly crackles/pops/backfires ( not really a backfire but almost) from the pipe at low speeds when I let off the throttle. I never really gave it much thought because it seems to run fine but talking to my dad about it, he said he doesn't think it should be doing this. Haven't called the dealership but that was going to be my next step.

Just wanted to ask if anyone knows if this is normal to the 800 or should it really not be doing this? Maybe the mapping is just not right? I would appreciate any input before I call the dealer and they tell me its normal or something...

Thanks alot.

Unfortunately it's normal for most modern bikes. The lean fuel/air mixture required to pass smog causes it. It can be remapped, if it bothers you, but it don't hurt anything.

I haven't heard one do that. It could be several things. I'd take it to the dealer to check out. You still have warranty so why not get it checked.

Mine is doing the same thing, shocked me the first time (a car was following me really close, thought it rammed me ) but it don't bothers me anymore, barely noticing it anymore.

It is normal. As you let off the throttle, the mixture goes mega lean ( naturally), and the hot exhaust now self ignites. If you have an aftermarket pipe, you notice this more, as they use a glass insulation, that tends to store a bit more of the gasses, than a baffle type, like the stock. It is quite normal.

Normal.... Especially on European bikes it seems. Heard its due too super restrictive EU emissions. They run very lean.

Some type of fuel management system might correct Issue, like a power commander.

Not every time and not loud, but it happens.

Thanks

Thanks for the input. I will probably call the dealer anyway and see what they tell me. I wish there was an easy way to remove what restricts the fuel mixture without going the power commander route. Big modifications scare me alittle.
