Default Backfire

Hi All,

I have a 2011 700R and when i open her up and give it some it often makes a back fire / cracking noise from the exhaust as i am changing gear or when i let off the gas. I wondered if this was normal? I thought it may be something to do with over fueling of some sort but i just wanted to ask you guys opinion. It is totally stock by the way.

Thanks

Its not burning all the fuel your giving it. Check the spark plug if its dark its running rich. If its tan its ok. If its white its lean. You running with or without the air box lid?

Is the air filter dirty?

Mine backfires a little sometimes same as what your saying when riding and changing gears but its really lightly and not an issue for the very little amount it does. Im not even worried!

Can you post a vid?

Mine does it quite often and really really loud!! I will give the spark plug a check and see how it looks. I am running it with the airbox lid off, but filter is clean.

That will cause it to run lean! Rich is better than lean anytime of of the week! Put that lid back on and see if that fixes the loud backfiring.

Mine is also stock the lid is on and No Loud BackFires at all. Just some little pops from time to time nothing to worry about at all in my case but your loud backfiring is cause for getting that lid back on pronto!

Ill be here watching for your reply!
