Hello, You guys are a wealth of information. Im still trying to sort out exactly what I have here. A mc18 rothmans with mc28 bodywork. I have rear linkage plates on the bike with all four holes in the picture in the plates. I dont believe the plate is installed correctly. the rear is real soft. I have the 70m holes on top with the 48mm hole at the front of the bike. The 69.7 mm hole is mounted to the suspension ...is this right. Thanks Guys.
