103,000 miles until a seal leak - wow! My left fork seal started leaking at ~25,000 miles. Anyways, I replaced my fork seals with an SKF kit and here's my experience. I found a small scratch on the fork but very minor. I went ahead with the seal replacement. The new seal leaked as well (although a lot less and only a slight film on the fork) for around 1,000 miles. I kept wiping it down every so often to make sure that bugs or dirt doesn't get in. Surely enough the leak started to disappear and then the leak completely went away. I read on a Suzuki form that there is a "break-in" period and this turned out to be true in my case. I have since put another 1,000 miles and it looks good.
Hope this helps
