I have both 09zx10r and 2012 zx6r on my zx10r i removed secondary butterflies in the throttle body and it gave a better throttle responce in lower rpm has anybody heard of doing this with a 2012zx6r I hate throttle response below 8000 rpm on zx6r
What it is you cut a piece of pvc piping and glue it on your throttle tube where the throttle cables rest. In doing so you cut the throttle movement in half. It's a cheap easy mod that takes about 30 minutes. Some people remove the tube all together. But I did it just fine with the throttle tube still on the bike .
