In our first video, we installed a top end kit on our Honda Grom. In this installment, John will show you how to install an aftermarket throttle body on the Honda Grom. Pay attention here, because we’ll need to make a few unexpected modifications along the way to make the Koso throttle body kit work on the Grom.

Once we wrap up the throttle body, we’ll install a Yoshimura exhaust system on the Grom. This, along with the throttle body on the other end, will help the motor breathe better. To accommodate that additional air, we’ll also install a Koso Hurricane air filter on the Grom. Like with the throttle body, this will require some extra modifications to make it work, and John will show you how to modify the airbox.
