EXCF 250, Cam chain tensioner oil leak (Tensioner question)

Recommended Posts

Hello, I have oil weeping out of the cam chain tensioner, I have tried nipping the 21MM bolt up but will not go anymore, the is also a 17MM bolt on the top of the 21mm, can I tighten that don't until it's snug or does that adjust the tension? As it's easily movable with a spanner at the moment, on the internet repair manuals don't show the tensioner having a 17mm bolt on top, is this tensioner on my bike aftermarket or genuine? pictures below!
