Tips

• Make sure engine is cold
• Always lubricate the rubber o ring with the waste oil on the new oil filter
• From empty, bike should have 1.13 liters of oil. NEVER FILL ALL THE WAY!
• Never start motor while the oil is drained
• Don't let anything other than oil in the oil tank pump or filter
• This should be performed every 10-13 hours of riding
• If oil is grey or milky this is due to water or burning the clutch when this happens the clutch basket gets so hot the metals start to break up into tiny shavings leaving you with a grey colour in your drained oil
• This procedure should take 10 minutes when you get comfortable with these steps

Warnings

• Engine should always be cold possible burn risk

Things You'll Need

• 13mm wrench or socket (lefty loosy, righty tighty)
• 1.13 liters of 10w/30 oil
• New oil filter (correct one for the bike)
• Oil drip pan
• Allen key set for the oil filter cover
