Hi, I just installed a Yoshi CF full system exhaust on my 2013 Ninja 300. I could only get a two brothers CF full system map. I'm using it now, but the bike's exhaust backfire/pops every now and then on decel. It seems to pop more at above 3500 rpm with the throttle closed and then slightly opened. That is when I can hear it pop. It's not bad, but I think it's because I'm not running the MAP.

Let me know if anyone has that MAP or has one that will work.

Did you remove the Kleen-air system when you installed a full exhaust? If not, that's the source of your popping.

Oh, no I did not. The instructions made no mention about that. I didn't even know the bike had one. I will look into it.

Thank you

Good catch chone!

Not sure how similar it is to the Kleen system on the 250R, but this should give you some idea of what to look for when taking everything off:

Thank you, I will look at this today. I guess the fuel tank has to come off again.
