Hiya, sorry I'm new to this, I've got a Yamaha DT R 125 2001 and no I'm no expert but I've got some knowledge on the basics, and very concerned as haven't found nothing on the internet about it, the thing was making me concerned is its bone dry theres no oil leaks, water leaks etc coming out of this hole, I'm trying to upload a pic as its hard to explain where it is exactly, but its not letting me upload anything bigger than 0.49 mb if you could help you'd be a great help cheers Brad
