hey wolfie,
The rack/rest combo you see on some of the gallery pics, ie yamaha slider sets are more rare than totally stock bikes .
i saw the set ups a few of the founders of the forum have , ron g.,Lucky and others . I downloaded the pics of the bikes they ride, the enlarged them enough to get a good idea of what i would need.
the rack from a honda cb-750 will fit on a vision, but you will need four 1/2 inch spacers ,8 flat fender washers, and 4 nut bolt sets, grade 8,1/4 inch by 2 1/2 inches .
the back rest can be made up at any area machine shop,,
you will need a 4 ft section of steel pipe, 3/4 inch outside diameter, and two sections of steel pipe 4 inches by 13/16 inside diameter .
have the 4 ft bar cut in half, then get it bent on a mandrel to an 85 degree inside angle(for the rear lean back)the bed should be about 8 inches of upright,the rest is slider
make a 6inch high by 9 inch wide block of plywood and cover with your choice of covering, drill the two uprights to bolt back pad onto (2 bolts per post )
the two short pipes are the welded onto the bottom of luggage rack crossbars,then have a 1/4 inch hole drilled 1 inch in from each end and have the welder tack a square nut onto each tube (to secure the sliding section of backrest .
The only down side to this arrangement is the rear grab handle has to be "chopped " just cut off the ears 1/2 inch from the end of top plate. if i can ever get my camera back from my kids, will get some pics of my set up for you ,, then you can download them, take to machine shop with you ,, if they see it , i bet they can make it . or, if you are planning any travel up i-85 , let me know, can meet you and let you see this for your self . give you a chance to see the set up, how is bolted, and how to mount the seca II saddlebags when you find those,, lol .(@30.0 to 50.00 on e-bay )
