Hi Guys & Gals,
I am a fairly new lady rider and in love with my FZ-07. I installed an M4 slip on exhaust which sounds amazing. There is some popping and backfire now and then and am wondering if I need to address that. I am not one to take my bike apart and work on it, just not that knowledgable. I have heard either ECU flash or EJK?? What do you experts recommend? The salesman at Yamaha says I don't need to do anything?!

From what I've heard is that's common. The popping and backfiring happen with the regular pipes you just don't hear it as bad. I think the salesman is probably right. I'm not an expert though you can ask around

I got the ECU flashed at 2wdw and it was well worth it. The bike is running great and a lot happier.
