I took the cover off one of my 160sx motors and it is plumbed just like the picture Dave posted. I was always told that line and restrictor assembly was metering fuel to lube the motor bearings. Harry...your motor must have a mod done to it, if you find out why it was done and how the bearings are being oiled please let us know.
