I need to remove the clutch from my pit bike so I can replace a broken spring. I have the right springs but I can't get them on without removing this centrifugal clutch. Only problem is I can't seem to get it off. What tool should I use for this thing http://imageshack.us/photo/my-images/809/moar128.jpg/ Front on view http://imageshack.us/photo/my-images/862/moar129.jpg/ So what you guys think? I don't want to pay a mechanic since it's a small job and don't want to have to spend anymore money on this play thing. It really is just a 50cc pit bike that I keep around for kicks and giggles. It's not worth anything. So how can I pop this thing off so I can fix her???
