I was wondering if the rockers on my kawasaki ninja zx6r are adjustable?(2001)?

Answer 1

The valve clearance is adjusted by removing the camshaft (s) and installing a smaller or larger shim under the bucket as stated in the above excellent answers. Intake clearance is .15 -.24mm and exhaust is .22 -.31mm.

To check the clearances you must remove the valve cover and rotate the motor with a wrench on the crankshaft. To change the clearances you must remove the camshaft (s). Critical attention must be paid to cam timing, locking down the tensioner and not dropping anything down the motor! It would take me a page of typing to give you all the details but a photo or two in the shop manual is worth more than my description.

Get the manual if you are going to give this a shot at home. It will save you money in the long run. Tools needed would be feeler gauges, a small torque wrench that reads inch pounds, and a metric micrometer is handy in case the shim numbers are worn off. You can cut a piece of rubber mat or heavy cardboard to insert in the engine cavity to keep any stray shims or bolts from trying to escape. A magnet is handy for pulling up the buckets by the way. Be careful of the plug caps and wires. The later versions were not as hardy and could break if you abused them. Good luck.

Answer 2

That model doesn't have rocker arms.
It has shim under buckets.
To change the valve clearance, different thickness shims are installed.
The camshafts have to be removed to adjust the valve clearances.
Not a job for newbies.
Special tools are required.
Micrometer & torque wrench - preferably 1/4" drive

Answer 3

Get a service manual for your bike. It will tell you exactly how to measure clearances.

It comes with a chart showing exactly what thickness of shim to install to gain proper clearance.

It's really not that hard if you follow the instructions carefully. It took my all day though to do mine --- I'm slower than most though.
