Well.......i call it the mongrel as its a bit of a collection from a few different models but i believe the frame is early MC18 so yes 2J but im fitting late MC18 R5k fairings and ive no idea if there different to early 2J.
I think i have them all sorted now bar the 2 S shaped brackets that attach to the lower panels and the engine somewhere im guessing although i must be missing something as i cant for the life of me work out where there meant to fix to.
