Update…
Well, the seat nose did start moving down towards the tank because it was too long, which was mentioned. This seat also moved me about two inches forward which wasn’t quite right for me. Couldn’t use the factory back reset due to the seat had moved forward. Bottom hamstring area had pressure them when sitting at a light. When riding, you had a two by four line on your lower back. That locked you in the seat, but after 60 miles the two by four got old.
Well I made an appointment and took my bike to Guy’s to have custom work to the seat. When he sat on the bike and noticed right away the two by four lower back pressure and that it kept pressure on your legs from coming down easy while holding the bike up. I made a second appointment to ride the bike with the new foam changes. This moved me back in the seat more and got rid of the two by four. No more pressure on the hamstring area when sitting at the light, and the nose was cut back off the tank. He nailed the seat for me. I only requested to shave the new foam down a little on the back rest. He then recovered the seat and both back rest, which I’m EXTREMELY happy with. The seat is very comfortable now!

I do not recommend this Mustang model 75486 unless you want a good base to start with and make it your own. Maybe I should have gone with the Sundowner Smooth Part Number 51929-01??
