I have a 1973 R75/5 and I noticed a fork oil leak at the bottom left fork. I went ahead and replaced both sides fork oil and crush washer. The right side is good/dry but the left side keeps weeping. I have tightened the nut snug then tighter, (holding with an allen wrench at bottom) I have tried different size crush washers but the left side still weeps. Why is right side good/dry but not left, any thoughts, what inside the fork might cause this?
thanks

My bike is a /7, so I might be off - did you replace the washer inside the fork leg (on the bottom of the damper tube), or just the external washer under the nut? To my knowledge, it’s the internal washer that is actually the seal. If you haven’t been in there, there is also a hard plastic bumper ring that resides at the bottom of the fork leg. These typically decompose into a broken-gooey-mess over the years. I’d plan to replace those as well.
