I took off the rear seat and also the metal plate attached to the front seat.
When I decided to put the back seat back on, I put a 2" wide strip of industrial Velcro across the rear portion of the front seat and matching hook/rug under the front part of the rear seat, so that they mate. Then I put the 2 screws back in the rear seat at fender.
So now if I want remove the rear seat, 2 screws only and I don't have that ugly piece of metal left over to deal with. If I want the front off, well that cost me another 2 screws.
I use to ride just solo seats on all my sleds. my kaw v2k, I took the seat off almost daily for mods or service, so I just velcro'd it in place. It worked great for 2 years. Until I put it on a trailer and hauled it to Salt Lake City. w/o somebody sitting on it at 60-70mph, the seat decided it wanted to be part of the mountain scenery. I had to order a new (used) one. so then I put a leather belt around it thru the frame to keep it from joining its cousin. it actually looked good and was ez to service and if ever I needed to slap theshit out of somebody, it was a handy tool to have quick access to. so many great ideas! poncho
