I am having a weird issue in the front. I had a similar problem awhile back. It is basically feeling "bumpy" in the suspension up front. Almost like when I had a chopped tire awhile back. I replaced it about a month ago with a michellin power pure and it fixed it then. This just started a day or two ago. Basically when I ride, no matter how smooth the surface, every few seconds it will act like I am hitting a small bump. Nothing really major but I can definitely feel it, and its starting to get a bit annoying. I am wondering if maybe it has something to do with the front forks, I noticed a small bit of oil coming from the bottom of the left front fork, and it seems when I lean into a corner the bumps get a little bit more noticeable. I am thinking maybe the oil is leaking out and causing the suspension to get a little weaker on one side, or if there is any kind of alignment adjustment on the front? I am not sure about that but I suppose it could cause it. It is not like a balance issue, and I still have all the weights on from when it was balanced about a month ago so I highly doubt that is it. Any ideas? Maybe front bearing?
