I have a 06 cbr 1000. It has arta full system, pair mod, power commander. I having a problem with deceleration popping almost like backfires. It sounds like a grand finale. I brought the bike from a good friend I cant remember if it always made the popping or if it started with the pair mod. If it was warmer out I would post a vid. It almost sounds like a super bike. Is this bad or hard on the motor. Has anyone else had this problem. Also the bike has about 6,000 miles on it.

 

I hear it all the time when downshifting for a corner at the track. Don't ride that hard on the street but if you hitting the redline then down shifting while breaking you are going to get a pop. Don't know if it is bad for it or not though.

 

No I don't hit the limiter or red line. It will don't it any time over 10,000 rpms. It will also do it if I ride the same speed around 70 mph. For along pried of it right when I cut gas (pop).

 

is it custom mapped?

 

sounds like you need it mapped

 

+1 to both above posts. Need to take it to a performance shop and have it mapped.

 

+1 on a good fuel map. My friend's bike did that for the longest time until he had it tuned. It was actually kind of cool to see the flames shoot out every time he let of the gas. Shame he got it fixed.

 

popping is usually (not always)caused by the engine running to lean.

When you have it wide open and then cut the throttle,Think of it as your bike taking in a huge breath of air (especially with your mods) and just as your halfway through your big breath someone hits you in the stomach... You cough... Basically when it is open throttle tons of air is coming in then you cut the throttle, as a result the ECU says wait STOP the fuel flow, but the air is already there, causeinga greater air to fuel ratio...
and more air+less fuel = explosion instead, of "fast burning"

You could fix most of this with a good custom map. Keep in mind though If it is too lean you will ruin a motor. Remember this is good for PROS because Lean=HP but...When they run it lean they burn through motors, and i am pretty sure most of us don't have a factory sponsor to give us new motors when ever we want.

 

Are you sure it has the PAIR mod done to it?

 

Am sure about the pair mod. Why do you ask? Im also so that the bike is not leaning out.
