from Slingmods with Ryker Rally that has max mount.  The you tube from Slingmods shows putting the backrest on a Ryker with the max mount but the Ryker does not have a fender.  My Ryker Rally has fender and a pan under the seat to protect the seat from spray.  It looks like I have to totally disassemble the whole fender and seat and cut a hole in the plastic pan under the seat to have this driver back rest work.  But, I am not real keen on cutting holes in the pan.  So thought some one else might have run into this problem too.
