oil chance

  1. Mechanical / How To
    Hi I'm wanting to change my gearbox oil on my 1982 yz 125 J. It's been sitting in the shead for 8 years. First which way does the sum plug turn? Second I've cleanned the tank, carb and horses and replaced air filter. Is there anything thing else I should check before I try and start it? Any help plz
