Hey all, I was hoping that someone would be able to help me out here. I have recently purchased a Pista, and I haven't ridden it very much because I have been waiting on parts. I finally got it all put together and was able to ride it around. I noticed that it is making an unusual sound whenever I am using a lot of pressure. When I am going faster and not using as much force, I don't even hear it. I think it is coming from the chain. It sounds like a clicking noise....does anyone have any clue what this might be? Has anyone else had any experience with this?
