2000' ZX9R Valve Adjustment Symptoms?
How can you tell if your valves need adjusting? Lately, I've been hearing a little noise, only while driving, from my engine. Also, taking it up to redline, doesn't seem as smooth as it used to be. It seems to be struggling a bit taking it up to the high RPM's. I am wondering, how do you know when the valves need adjusting? The engine is not making the chattering noise when I throttle it up in nuetral, but when I drive it, is seems to chatter a little and is worse when cold.
What happens it the valves don't get adjusted?
