PETCOCKS
 

This document will help you to see the differences with the original CJ petcocks and the poor quality ones that just look like it and can cause you some troubles.

This picture shows 2 petcocks : the one on the right is the original CJ one, the one on the left is the poor quality one. Look the same ? Wait to see what’s next…
 

Picture 2 gives us some tips to recognize the good one from the bad one : As you can see they have little differences in shapes. Another tips is that the poor quality petcock(on the left) has been painted with a silver paint, when the good one(on the right) has a natural color, no paint.
 

Picture 3 shows us another difference of shape between the knob that allows us to open/close the petcocks. The bad one has a more beautifully made knob, when the good one has a very rough made one. Some of the good one come with a different type of knob.
 

Picture 4 shows us a Chinese character sported by the bad quality petcock. It is not found on the good one.
 

You can see clearly that the reserve on the good quality petcock (right) will allow you to drive longer than the one on the poor quality petcock (left).
 

Picture 6 shows us the differences between the good petcock (right) and the bad one (left) after removal of the bowl. The good quality one is brass the poor quality one is painted over and it is not a brass pipe.
 

Picture 7 shows us the differences between the fuel strainers located inside the bowl. It is clear that the brass screen on the right (from the good quality petcock) is of much better quality than the one found in the poor quality petcock (left).
 

Picture 9 shows us inside the petcock after removal of bowl and fuel strainer. What we see is that the poor quality one (left) has the inside painted and the good quality one (right) is natural color. Also note the poor quality of the casting on the poor quality one.
 

Picture 10 shows the sealing ring for the bowl : obviously the one on the right from the good petcock is of far better quality than the one on the left from the poor quality petcock.

The conclusion is :

The poor quality petcocks are painted inside and outside and that paint peels off in contact with gasoline and it will clog the petcock and your bike will not work properly. The poor quality of the sealing ring for the bowl will make it leak and as its reserve is smaller than on the original petcock, you’d better be near the gas station if you do not want to push your bike!
