I think my bike's already been geared up by a previous owner, it does top out over 90, someday somehow. I don't feel comfortable holding the throttle wide open all day though, that can't be good on anything. It just cant pull the gear. I'm going to count the teeth.
Re-jetting it? Will do. I suppose the EPA had something to do with this.
I like that link.
Someone actually lowers the bike half an inch? You must be short!
