THIS IS ONE CARBURATOR REPLACEMENT 

DIAPHRAGM FOR THE KAWASAKI FX400R VACUUM VALVE

Some years have different types of carbs for the same year listed

 

so look closely at the measurements in the photos and part number.

 PLEASE CHECK YOUR PART NUMBER TO MAKE SURE 

THIS IS THE ITEM YOU NEED. 

EMAIL WITH ANY QUESTIONS.  

  

YOU GET WHATS IN PHOTO. 

You can find many guides and videos on the internet of how to change 

these but it just looks easy but it is not. The parts are very fragile and 

delicate so I strongly advise the change to be done by a professional. 

If you are not sure about the sizes of the diaphragms you need or you 

have any doubts please get in contact with me and I will discuss it to 

avoid any problems. The diaphragm itself does not have separate 

part number and the reference KAWASAKI part number for the entire 

Diaphragm Valve Assembly is 16126-1159 . So according to that 

number the diaphragms above should fit the following models:

Kawasaki 16126-1159 VACUUM (DIAPHRAGM ONLY) and can be used on these models and components:
