Disabling AIS on my FZ1

Took half day off work today for 2 purpose: 1st, to clear my remaining leave from last year before the company forfeits them and 2nd, to use this time to do something to my bike: disabling the Air Induction System.

Why do I need to remove something that is designed by the manufacturer to be placed on the bike? According to what I have read, it is to aid in the complete combustion of leftover fuel that is left unburnt in the combustion cycle. However the drawback will be getting popping sounds during deceleration. While the stock exhaust will absorb most of the popping sound and more evident in aftermarket slip-ons, I still feel uncomfortable knowing that there is popping sound occurring in my ride. The solution to this? block off the air supply to prevent the AIS from functioning.

Took me a while to remove the tank and airbox cover for the first time. Compared to my previous bike, Yamaha did not provide a way for me to hold the tank in its lifted up position (which means either you remove the tank totally or hold it with your hand) Honda however provided a way for me to hold the tank in its lifted position without removing the tank at all. That's a downer for me....upon opening the airbox cover, it is easy to find the AIS air hole as shown in the picture.

The little hole next to the filter

As opposed to what some did by using a marble ball to block off the air hose, I had decided to use a 20-cent coin, blu-tack and duct tape to do this job, since I had a very hard time trying to find a marble ball from most of the provision shops I had came by.

Securing with duct tape

Covered the airbox and put everything back into place after that. At current state I probably will not see much difference at the moment but will monitor what other benefits/issues I will get from this DIY mod.
