Power commander does not get rid of the popping. I had it on my Fz8 without blocking the hose and it was there.From what I understand get a Power Commander and you'll get rid of the popping with the proper map. Also keep in mind that designs by manufactures are done so for many reasons such as market placement in categories such as insurance, wide variety of customers, etc. if they came out with the most powerful bike possible it would eliminate potential customers. Bikes are designed with specific targets like the FZ8 is designed as a commuter bike. This fact doesn't mean that a user of this specific bike shouldn't modify the bike to meet their desires. Just realize that if you modify one thing that it will effect others and additional mods may be necessary to take full advantage.
