Kx 125 gearbox leak! Help

Hi i have a 2002 kx 125 thats leaking from the small sprocket area, its leaking oil and drips about a half a cup a day! Please help!!

Step 1 buy yourself a repair manual.

Step 2 buy yourself counter shaft o-rings.

Step 3 open manual.............................................

Yep thanks i dont know where to buy a manual tho.. Also i looked it up online thanks so much. If you could give me a link for a manual that be great!

And a new out put shaft seal too. There easy to change out and also check the out put shaft bearing too. I blew a shaft bearing before. Yours might be worn out a little to start to leak.. And a repair manual will be a huge help in you fixing years to come.
