Just like factory, but you only get one install, bowl gaskets will expand.
Rubber gaskets for the bowls are great fit and quality. 2.0 on valve needle seats which is correct for 94 zx9r.
Well follow up, bowl gaskets will expand and not fit after removing the bowls to replace main jets. The gaskets are ok if your gonna replaced them but once you go back in the carbs later if your rejetting, your one sick puppy. Do not throw away your originals orings!
The rubber in this kit is incredibly cheap and is horribly out of tolerance, complete waste of money, float valves and needles are the only thing usable, unfortunately I purchased them because I needed the rubber... update.... needle valve and seats failed and fuel locked my engine... will be looking for another supplier other than k&l.
