I just picked up a 2015 F6B Deluxe. The previous owner put a backrest for the driver on it, I'm a bit short (only 5'5" with a 29" inseam), I love that it had a back rest on the stock seat. However it is just a bit too far back for me (about 1.5" to 2") does anyone know of a bracket or extension that can push it forward just a bit? Thank you in advance.
