Hey, quick question before I go to the dealership for a manual. I need help on getting the rear sprocket off this old beast. We are stripping it down and reverse engineering it using Pro-Engineer software and it seems like the sprocket is almost permanently assembled to the damn thing! Which I know can not be. I will post some pictures later from my BlackBerry when I get home from class. Hopefully someone on here tinkered with one before. Thanks!
