I think I found the speedometor sensor. Is this it? I removed the one bolt holding it in, but it seems to be frozen in place and I'm afraid I'll break it or something else if I try to force it out. My speedo goes in and out and I'm hoping this solves the problem. I'm hoping to remove it and get a good look at the unit to find the right part. I'm afraid I won't be able to find a new one so I don't want to damage it. Does anyone have a picture of the unit once it is removed? I went to the 3sx site and I don't see one for sale. I searched on-line and some vendors advertise the part for like $20.00, but I don't want to spend the money only to find they sent me the wrong part!
