ninjette.org - View Single Post - DIY- Replace fork seals, dust seals and fork oil

A couple more questions: Are these a completely different type of fork than the pregen? I ask because the ninja250.org guide says that 5W fork oil is for a completely different kind of forks and that I should be using 10W oil at a minimum. It looks like everyone here is is saying to use 5w (common weight) or 8W (specified but generally unavailable weight), which both contradict the other guide if they aren't a different kind of forks.

Next, when I took it all apart, I found some rubbery substance around the bolts at the bottom of the forks. I cleaned it off thinking that it was bits of the paper towel I was wiping them with but realized afterwards that it was not. I will be monitoring them to see if they leak without it, but what do I use if I do have to reseal it? Is it some kind of liquid gasket? All this guide says to use is service-removable thread locker, which I assume is not a rubbery compound.
