I have a 2006 trailblazer 250 I hear a clicking noise down by my front sprocket I think it might be a gear messed up I'm looking for a parted out 250 so I can just change the hole thing Maybe that will be cheaper? any input? thanks

 

Replacing your existing sprocket with a used one from another bike, I personally have never cared for doing this as the sprockets and chain tend to wear together. My advise is replace your existing sprocket with a new one.

If you are hearing a clicking noise put the bike up on blocks and test, make sure its not coming from the suspension or elsewhere. I would also look carefully behind the sprocket as there may be a stick wedged up there that is hitting the chain/sprocket as it rotates. I've had that happen before.

 

you sure it's not just the spoket or chain worn out or loose wherere the chain is not seating on the spoket correctly. like mentioned above it's not that hard to check and replace it if you have too. imo.
