DIY Air Intake System (AIS) Block Off Install

We've all seen those really cool AIS block off plates, and they're not that expensive or difficult to install. Why do we need them? Some will say weight, but they weigh naff all so I call that a wank. I fitted them to the FZ1, and immediately that annoying popping on deceleration was completely gone. It's no surprise that the R1 with the GYTR pipes is popping and carrying on like the guns of Navarone.

Yamaha's AIS - pumps fresh air into the exhaust to cheat CO emissions testing

Time to fix all that popping. But I couldn't be bothered waiting days (more like weeks) for the parts to turn up... and I had some stuff in the shed I figure I can achieve the same result.

This is all you'll need:

Pliers, #2 Phillips, flat blade, stumpy flat, 5mm hex key, 
1/2" carby bungs (x3), stainless steal hose clamps (x3), zippy tie
As always, you'll need a rag (not shown)
