Here's my 2 cents on the seat mod.
I didn't like the flexibility of the seat (plastic pan), so my bracket adds stiffness in that area.
Also, I didn't have to move or remove anything so it's reversable.
What I don't like is that I'm sitting quite a bit higher.
LS 650 Sportster Seat Mod ala Verslagen1
Required ingredients: Suzuki LS650, 27" Sportster Seat, 12x12" Framers Tee bracket, various screws and (2) Ø1/4" x 3/4" Speed Pins.
First bend the bracket to match the frame.
The seat has molded in part number RDW-92/61-0067
Now attach the bracket to the seat. I used a 1/4-20 bolt and held it inplace with a funky wrench while I tightened it down.
Notice the speed pin for attachment to the frame.
Also, the rear clip is made from the original HD seat front bracket. Cut one hole off, cut the ramp down and wrap it with some electrical tape to keep it from rattling.
You'll need to bend the stock seat brakets up until they are verticle. And then drill a 1/4" hole into the frame on each side for the speed pins.
To install: hook the rear tab on the seat to the metal loop and drop the seat until aligned with the seat brackets insert the speed pins, one on each side.
Finito!
