Water can enter the oil in your 2000 KTM 65SX due to several reasons, such as a faulty water pump seal, a damaged head gasket, or condensation forming within the engine. If the bike has been running hot or if there’s been heavy rain during a ride, moisture can also accumulate. It's important to check for any visible leaks and to regularly inspect and maintain the bike to prevent further issues. If water contamination persists, it’s advisable to consult a mechanic for a thorough inspection.
40-1 is what i would run 50-1 is what AMSOIL recommends. Less smoke, cleaner plugs, great lubrication. Use what the manufacturer of the oil says for your application. That would be 50:1 with AMSOIL Dominator or Interceptor 2 cycle oil.
KTM recommends Motorex Top Speed 4T 15W50.
