Been meaning to post this for ages. Found this on the garage floor months ago, it's off my '77 Blade but I don't know where from.
Its a rubber stopper that goes underneath the riders seat at the front, there should be 2 of them attached. Yes, i need to get out more!
That is what I thought because I found it after poncing about with various stuff under the seat but couldn't see where it/they go. Poor design for Honda. Anyway thanks. (Stay in, don't go out more I might have other queries like this)
