I recently bought a 1991 zx11, C2 with 20k. The seller told me that the previous owner before him did the 3rd oiling line mod. I removed the motor last week to inspect all the plain bearings and was not surprised to see the 3rd rod bearing with a big scratch. Just ordered an OEM bearing to replace it.

***How can I tell if I have the oil bypass mod installed?***

My oil pan, I have 4 holes in it that hold a total of 5 oil lines, one hole holds two lines. I just can't tell if I have this 3rd oil line mod done or not? I also have a few pics of the oil pan. I can email you the pics. Please respond or email me at lifeisgreat189@yahoo.com
