How hard is it to get to the spark plugs on the zx12

Hard to install spark plugs are a bit discouraging especially when you are trying to do the job yourself and save the most amount of auto maintanence repair bills you can, hard enough doing this, you encounter at least one if not more spark plugs that just seem to be too hard to get your socket and ratchet on for either removal or worse yet, you have it out and can't get the new plug back in.....WHAT DO YOU DO NOW........
case solved, always have available a length of vacuumn hose bought from your local Auto Zone or the like...bring a spark plug into the parts store and ask the folks to get you a size that fits real tight on the spark plug tip, once found buy at least a 6" lenght of it, you will be amazed how nice this works....it is like owning your own "Snap On" Speciality Flex Socket for difficult spark plug installations, great to get the spark plug threads started as well as it eliminates the worry of stripping the threads if the plug is installed cross threaded by means of starting it with a non forgiving steel socket, whether it be flexible or rigid.
Hope this helps you, I know for many years this little bit of advice has saved me time and time is money!!!
Have Fun!!!!
