Lightbulb Backfire in low rev's

Hi there guys, I'm kinda new to your forum and i am having a small issue with my beemer.


Well everything started a month ago, i purchased some folding levers and fitted them on the bike.So when i went for ride the bike did a really weird thing,While in low speed like 1st or 2nd and low revs like 2k to 4k when i was closing the throttle something with the iddle wasn't going right.I mean it was about to die and sometimes it did.
So my first guess was the small switch under the clutch lever (and since i have shift assist i knew something was wrong). So i adjusted the metal plate to hit the switch at aproximatly 44 to 50 mm as i read somewhere.I had no luck with it so i checked the air filter (that was my second guess).Nothing there either the air filter was good as new.
So my next guess was the injection and since i have 10k kmh on the bike i bought today an injection cleaner fluid and went for a ride.It seemed better so i pussed a bit , i've started to accelarate and braking hard and fast, and in first gear it started backfiring in really low revs like 2k to 3k and then it died .There wasn't any flames out of the slip on but i could hear' em in the pipes.It sounded more like a snorring actually but it was backfires in the pipes,Really weird :S.
I don't know if this has anything to do with the battery since i have xenons on the bike and i still haven't check the battery.Btw the bike iddles great just like a clock and this thing occurs only when i pull the clutch and i already have gear on the bike and the rev's drop.
i Have stock exaust and an akra slip on and the oem air filter.
Any suggestions ? I could really use some

I say it's the stealership's problem. Maybe that's just because I don't know much about diagnosing the problem.

Id say the back firing is from the injector cleaner...run the rank low and put some fresh 92 in and see if the problem persists, if so, have your dealer diagnos
Good luck and let us know what you find...

If you turn the key on with the bike in gear and side stand up will the bike start when you hit the start button. Then try it by pulling the clutch lever in. Does it start then? If it does start without pulling the lever in you have a problem--be careful as the bike will lurch forward--it shouldn't start this way. If it starts when you pull the lever in then you should take it to the dealer and have them work on it. If it doesn't start with the lever pulled in then you have a clutch switch issue. This needs to be rectified.

If the bike thinks the clutch is pulled in it can do all kinds of weird things.

I agree with both,
Run the injector cleaner out and try with fresh gas.

If your clutch switch is messed up you oughta be careful.
