Old HD guy; Multistrada noob here. Please go easy on me. I purchased a used 2017 1200S a couple months ago. The seat was in the low configuration. I added the three brackets to raise it in an attempt to keep me from constantly sliding into the gas tank. Pic from workshop manual is below. The eccentric is missing from my bike. Is it something I need with the raised seat? Any idea why the manual reads like the eccentric is an option? Thank you.
