Anyone have 200x knowledge

[stevo3176]

I picked up a 200x recently with a smoked clutch. I have to take the clutch plate off to change the plate but it has a nut that I am not familiar with. It is a circle with 4 grooves on it top and bottom and both sides. Is this a common socket or is this a honda part?

Ask over at www.3wheelerworld.com They are very helpful! BTW, you need a special socket to get that nut off. 3WW should tell you how to make one. ;)
