Side oil drain plug
Since I have been working on my son's and my 750s I have been using 0-rings from the big box set(s) at Harbor Freight. It seems as though there are 2 in each, metric and SAE that "fit" the drain plug. Since we are replacing the tie rod and now the oil pump chain among other odds and ends I ordered a stock Kawasaki o-ring for the drain plug. It is nothing like the ones from Harbor Freight. It is really thin, about 1/2 as thick but pretty much the same outside diameter.
I was wondering what one others have been using? I have been going with the 219 or 220 from either box (red or blue) and other than having to re-tighten it after changing have no real complaints. Although my 03 leaks more than my son's newer model. I am afraid it is a case leak not a drain plug. A project for another day.
