250rBeast, So yours has one to maybe, this one was a clean cut but seems way to big for a greese nipple, I had 1 85 swing arm no hole, 2 86 ones and no hole, and then the one that was on the 87/86 had it, I used it for shooting penetrating oil into it, the chain adjuster always worked better on this one, I am trying to think but I beleve my westcoast swing arm has a greese fitting on it.
But how the hole was on the factory swing arm was cut really nice, or stock, it had factory paint on it and on the side of what would have been cut was the stock paint as well.
