I believe my Cbr600rr uses a different specialty tool than the tool posted in the US instructions. Does anyone have the 008amy002 tool? It look like it’s going to pretty much be a 36 mm Allan wrench. If you do could you measure it for me? I was going to make a tool with some hex bolts, but need to get the bike together asap. So I’ll probably refresh it at a later date. Attached pics. US instructions, instructions I found online with different tool, picture of the clutch

If you have not solved your issue for this yet I just put one of these on yesterday and I used the Racetech tool for a 636 suspension. https://www.partsgiant.com/p354405-...8UY23A2EgfzLnIZGJBUCpSZqFW4Qnx_xoC_L0QAvD_BwE
