Hey I have a 2007 zx6r I’m pretty new to riding. Anyways my question is when I use to give gas to my bike like full throttle my bike use to pull you can feel the power but now I tried giving it full throttle it’s not the same as before it’s more smooth it feels slow. What do you think the reason is my rear tire pressure is like 26 psi which is pretty damn low and my battery is low to I need to trickle charge it what do you think the reason is that my bike feels slow is it the tire pressure being low or could it be something else I’m new to riding btw really appreciate it if you let me know what you think the problem is.
