You mention PVC storage.
When I got my Intruder I slung a piece of 4" PVC under the back for hose storage... Imagine my feelings when the fittings on the end of the hose would not fit in the pipe (I now use it for other stuff) So I slung a length of six inch right beside it. This is slung transverse about 8 feet long, with caps on each end, one permenate one with a clean out plug They bolt to existing holes in the frame (no drilling of frame) and on each one I drilled a pair of holes in the BOTTOM of the pipe (in line with the holes in the top where the bolts go) big enough to pass the wrench socket to reach the bolts.
When done I reamed that bottom hole out just a bit and solvent welded (PVC PIPE "Glue") 90 degree elbows in pointed back (Drain holes should any water get in the storage pipe)
Nothing adds excitement like something that is none of your business.
