I am new to this site and have a question. I am replacing the rear sprocket on my 1998 Xplorer 300 and have hit a snag. I tried removing the bolts holding the sprocket on and found that the bolt head is round and is recessed in a round hole. Either something is broke/wrong or I am missing something. I have no idea what to do next... Thanks for the help.

I have to cut them off the nut that is with a wizzer or you can try a good impact and tap with hammer on head of bolt when spinning impact ot jam a old screw driver or punch in beside head of bolt or just grind off nut

Okay. It's looking like I'll have to cut them off.

If it helps, the sprocket is attached to a hub and the bolt heads are recessed in to the hub, not the sprocket.

You have to take the bolts #20 loose to get the sprocket guard #17 and spacer # 18 off first. The sprocket #19 is mounted to the sprocket hub #22 by studs #21 that are press fit into the hub like wheel studs. There shouldn't be any reason to have to grind or cut them off. Use a little JB Blaster to soak them or maybe a little heat on the nuts #16 after removing the guard. They probably have thread locker on them that needs to be softened up to let them turn.
