STOP! Soak the screws for a few days with KROIL (NOT WD40!!) and STOP trying to loosen the screws using a Phillips screwdriver! It will not work because they are NOT Phillips screws; the are JIS (Japanese Industrial Standard) screws! All you will do, as you are learning, is strip them because that is exactly what a Phillips screwdriver is designed to do.

Here is the lowdown on JIS screws and instructions for modifying Phillips bits so they will work in these screws. Follow these instructions and you will have more success:

You really need to throw the WD40 in the trash; it will not serve as a good penetrating oil, lubricant, or contact cleaner. About the only thing it works well at is removing gummy price labels from REAL penetrating oil containers. Kroil can be ordered from Kanolabs.com Here's the scoop:

Cool, thanks alot. Im new to kawasaki, so all the help I can get is great.

I meant to mention - Kroil can sometimes be found at gun shows or gun shops although most shops don't carry it. Ed
