you need everything. I beleive your grips will work but you will need the throttle button, tach, hood harness, smoothing coils and all regulators and relays. if you can, get the piece of metal that the relays mount to on the lh side, you need the thumb and grip switches. you could use your single bulb light and just plug one in but would look good to have dual bulb in a red sx, get the red sxviper seat as well. you need coil packs
I have a pod and headlight and windshield if you want to change the top to match
If you are missing anything let me know or have questions about conversion, I have done a couple here
