My friend just got a beat up 87 250x that needs a lot of work. One thing we can't figure out is the chain adjustment. Are we not seeing something, or is something missing/broken? The bearings are SHOT so we haven't really concentrated on it, but any help is greatly appreciated.

 

the chain adjustment is gonna be on the right of the sprocket.you gotta loosen the bolts below it before it turns.i was confused also at first

 

2 metric HEX bolts on the back of the swingarm, loosen these then there is a round tensioner on the right of the sprocket like he said. slide somthing into one of the three grooves and push down this will spin it and tighten the chain.
